Hide command in ABAP Objects

Hi everybod,
i got a small Problem with the HIDE command in ABAB Objects. I got a Method called
write_on_screen( ). in this method i  got code like this:
DATA:
    test TYPE c.
test = 'Hello'.
WRITE: /0 sym_minus_folder AS SYMBOL HOTSPOT.
WRITE: /5 'Im a dummy line'.
HIDE test.
Then i got this message "You cannot use HIDE with a local field."          
If i change the code like this
WRITE: /0 sym_minus_folder AS SYMBOL HOTSPOT.
WRITE: /5 'Im a dummy line'.
HIDE _test.
_test is an Attribute of the class with the type c. "HIDE is not supported with the attributes of classes.     "
Maybe someone got an advice for me.
Greetings

  • HIDE Command in ABAP

    What is the exact purpose of using a HIDE statement while making an interactive report? I know it is needed , but what purpose it exactly solves.

    F1 help.....
    HIDE
    Basic form
    HIDE f.
    In an ABAP Objects context, a more severe syntax check is performed that in other ABAP areas. See Constants not allowed in HIDE area.
    Effect
    Retains the contents of f related to the current output line. When the user selects the line from the list f is automatically filled with the retained value.
    The selection can occur in:
    AT LINE-SELECTION
    AT PFx
    AT USER-COMMAND
    READ LINE
    The contents of the field do not have to have been displayed using WRITE in order for you to retain them.
    The HIDE statement does not support deep structures (structures that contain internal tables).
    Useful system fields for interactive reporting are listed in the System Fields for Lists documentation.
    Note
    Lines or components of lines of an internal table that you address using a field symbol (see ASSIGNING addition to the READ and LOOP statements), cannot be retained using HIDE. You can store them using a global variable instead.

  • AT NEW command in ABAP Objects

    Hi everyone!
    Is there an equivalent of the AT NEW command in abap oo? When I try to use this command inside a BAdi, I get an error message.

    Hi,
    Thank you for your response

  • Abap objects and selection screen

    Hello everybody,
    I am interested in your ways of implementing selection-screens in the style of ABAP Objects.
    In earlier times (when I used to implement ABAP objects in a procedural way) I just put the selection-screen commands in an include or a form routine of my ABAP report. So it was possible to run the report in background.
    Now I read something about selection-screens/dynpros and "separation of concerns" in the book "ABAP Objects" written by Keller. He advises using function groups to encapsulate presentation from logical matters. (Selection-screen commands are in an automatically generated include now). I implemented this way. (ABAP report with a local class, which has a main method, where function module of the function group is called). It works, but i see no chance to run my report in background now.. but I need to run the report in background.
    Does anybody know a solution without deleting function group?
    What do you think is the best way of using selection-screen-commands and ABAP Objects, especially regarding running in background?
    Thx for your advise in advance.
    Kind regards,
    Anne

    Hi Naimesh,
    thx for explanation. I am not sure, if I understood everything in the right way.
    Where do you write the code for building the selection-screen? (PARAMETERS, SELECT-OPTIONS etc.)
    If you write these commands in a class method, you will get a syntax error ( because it's forbidden per definition of ABAP objects). So, am I right assuming that you put the coding just at the beginning of the ABAP report ? And after START-OF-SELECTION-event you start the processing... ?
    Furthermore, I don't really understand why you create an separate class for ALV. I found your "SAP abap help"-blog, where you explained the concept of MVC ((By the way, well done!), but you didn't mention an "ALV class" there..
    Mh.. another question - have you ever combined MVC with object services?
    At the moment I'm working on a software project where I use object services. I created 2 persistent classes via SE24 and one local class in my ABAP Report.
    I don't really see possibility to implement MVC in this project without change very much of coding and class structure...
    In my opinion the M (data&business logic) are my existing global classes and my local class is kind of Controller class?!
    Thx in advance,
    Anne

  • Logical Database in Abap Objects

    Hi to All
    I want do it a program report using a Logical Database.
    Is this possible ??? But when I make a GET <node>, occurs the following error:
             "" Statement "ENDMETHOD" missing.  ""
    I'm doing the following:
    CLASS MONFIN IMPLEMENTATION.
           METHOD TRAER_DATOS.
                   GET VBRK.
           ENDMETHOD.
    ENDCLASS.
    Please, somebody tell me how I use the logical database in Abap Objects.
    Thank you very much
    Regards
    Dario R.

    Hi there
    Logical databases whilst of "some use" are not really part of OO.
    If you want to use a logical database in an abap OO program I would create a special class which just does the get data from your DB and pass this either at record or table level.
    Techniques such as GET XXXX LATE aren't really part of any OO type of application since at Object Instantiation time you should be able to access ALL the attributes of that object.
    As far as OO is concerned Logical databases are a throwback to "Dinosaur Technology".
    Since however modules such as SD and FI are still heavily reliant on relational structures (i.e linked tables etc)  then there is still some limited life in this stuff but for OO try and solve it by another method.
    If you really must use this stuff in OO then do it via a FMOD call and save the data in a table which your method will pass back to your application program.
    You can't issue a GET command directly in a method.
    Cheers
    Jimbo

  • How to implement Strategy pattern in ABAP Objects?

    Hello,
    I have a problem where I need to implement different algorithms, depending on the type of input. Example: I have to calculate a Present Value, sometimes with payments in advance, sometimes payment in arrear.
    From documentation and to enhance my ABAP Objects skills, I would like to implement the strategy pattern. It sounds the right solution for the problem.
    Hence I need some help in implementing this pattern in OO. I have some basic OO skills, but still learning.
    Has somebody already implemented this pattern in ABAP OO and can give me some input. Or is there any documentation how to implement it?

  • Begin-of-transaction in ABAP Objects

    Hi,
    I have a question regarding the (implicit or explicit) begin of a transaction (read: SAP LUW) in ABAP Objects. In this piece of code
    CREATE OBJECT mapping.
    TRY.
      mapping->delete_all_embraced_mappings( ).
      mapping->merge_with_begda_overlap( ).
      mapping->merge_with_endda_overlap( ).
      mapping->store( ).
      COMMIT WORK.
    CATCH /my/mapping_exception.
      ROLLBACK WORK.
    ENDTRY. 
    I need a all-or-nohting logic, i.e. I'd like all the methods <i>delete..(), merge..()</i> and <i>store()</i> to run in a single transaction. If any of the methods throws a <i>/my/mapping_exception</i> I want all DB changes (carried out in the methods) rolled back.
    Now, how can a mark the <b>begin-of-transaction</b> (the counterpart of the commit work)? I couldn't find information about this in the docu or in the SDN. To prevent misunderstandings: I am building a web application with ABAP Objects, so no dialog steps, PBO-PAIs, function modules, performs etc. are involved!
    Regards,
    Sebastian Kamp

    Maybe by using
    SET UPDATE TASK LOCAL
    I think this command acts as a BeginOfTransaction command, it especifies that, till the next CommitWork, all the process has to be done as part of a Transaction.
    You could try something like this:
      TRY
          SET UPDATE TASK LOCAL
          <YOUR_PROCESS_HERE>
          COMMIT WORK
       CATCH
       ENDTRY
    Hope it helps.

    RFC is an SAP interface protocol. Based on CPI-C, it considerably simplifies the programming of communication processes between systems.

    RFC is an SAP interface protocol. Based on CPI-C, it considerably simplifies the programming of communication processes between systems.

    Methods in ABAP Objects - Example
    The following example shows how to declare, implement, and use methods in ABAP Objects.
    Overview
    This example uses three classes called C_TEAM, C_BIKER, and C_BICYCLE. A user (a program) can create objects of the class C_TEAM. On a selection screen, the class C_TEAM asks for the number of members of each team.
    Each object in the class C_TEAM can create as many instances of the class C_BIKER as there are members in the team. Each instance of the class C_BIKER creates an instances of the class C_BICYCLE.
    Each instance of the class C_TEAM can communicate with the program user through an interactive list. The program user can choose individual team members for actions. The instances of the class C_BIKER allow the program user to choose the action on a further selection screen.
    Constraints
    The ABAP statements used for list processing are not yet fully available in ABAP Objects. However, to produce a simple test output, you can use the following statements:
    WRITE [AT] /<offset>(<length>) <f>
    ULINE
    SKIP
    NEW-LINE
    Note: The behavior of formatting and interactive list functions in their current state are not guaranteed. Incompatible changes could occur in a future release.
    Declarations
    This example is implemented using local classes, since selection screens belong to an ABAP program, and cannot be defined or called in global classes. Below are the definitions of the two selection screens and three classes:
    Global Selection Screens
    SELECTION-SCREEN BEGIN OF: SCREEN 100 TITLE TIT1, LINE.
      PARAMETERS MEMBERS TYPE I DEFAULT 10.
    SELECTION-SCREEN END OF: LINE, SCREEN 100.
    SELECTION-SCREEN BEGIN OF SCREEN 200 TITLE TIT2.
      PARAMETERS: DRIVE    RADIOBUTTON GROUP ACTN,
                  STOP     RADIOBUTTON GROUP ACTN,
                  GEARUP   RADIOBUTTON GROUP ACTN,
                  GEARDOWN RADIOBUTTON GROUP ACTN.
    SELECTION-SCREEN END OF SCREEN 200.

    ENDCLASS.
    Note that none of the three classes has any public attributes. The states of the classes can only be changed by their methods. The class C_TEAM contains a static constructor CLASS_CONSTRUCTOR. C_TEAM and C_BIKER both contain instance constructors.
    Implementations
    The implementation parts of the classes contain the implementations of all of the methods declared in the corresponding declaration parts. The interfaces of the methods have already been defined in the declarations. In the implementations, the interface parameters behave like local data.
    Methods of Class C_TEAM
    The following methods are implemented in the section
    CLASS C_TEAM IMPLEMENTATION.
    ENDCLASS.
    CLASS_CONSTRUCTOR
      METHOD CLASS_CONSTRUCTOR.
        TIT1 = 'Team members ?'.
        CALL SELECTION-SCREEN 100 STARTING AT 5 3.
        IF SY-SUBRC NE 0.
          LEAVE PROGRAM.
        ELSE.
          TEAM_MEMBERS = MEMBERS.
        ENDIF.
      ENDMETHOD.
    The static constructor is executed before the class C_TEAM is used for the first time in a program. It calls the selection screen 100 and sets the static attribute TEAM_MEMBERS to the value entered by the program user. This attribute has the same value for all instances of the class C_TEAM.
    CONSTRUCTOR
      METHOD CONSTRUCTOR.
        COUNTER = COUNTER + 1.
        ID = COUNTER.
      ENDMETHOD.
    The instance constructor is executed directly after each instance of the class C_TEAM is created. It is used to count the number of instance of C_TEAM in the static attribute COUNTER, and assigns the corresponding number to the instance attribute ID of each instance of the class.
    CREATE_TEAM
      METHOD CREATE_TEAM.
        DO TEAM_MEMBERS TIMES.
          CREATE OBJECT BIKER EXPORTING TEAM_ID = ID
                                        MEMBERS = TEAM_MEMBERS.
          APPEND BIKER TO BIKER_TAB.
          CALL METHOD BIKER->STATUS_LINE IMPORTING LINE = STATUS_LINE.
          APPEND STATUS_LINE TO STATUS_LIST.
        ENDDO.
      ENDMETHOD.
    The public instance method CREATE_TEAM can be called by any user of the class containing a reference variable with a reference to an instance of the class. It is used to create instances of the class C_BIKER, using the private reference variable BIKER in the class C_TEAM. You must pass both input parameters for the instance constructor of class C_BIKER in the CREATE OBJECT statement. The references to the newly-created instances are inserted into the private internal table BIKER_TAB. After the method has been executed, each line of the internal table contains a reference to an instance of the class C_BIKER. These references are only visible within the class C_TEAM. External users cannot address the objects of class C_BIKER.
    CREATE_TEAM also calls the method STATUS_LINE for each newly-created object, and uses the work area STATUS_LINE to append its output parameter LINE to the private internal table STATUS_LIST.
    SELECTION
      METHOD SELECTION.
        CLEAR BIKER_SELECTION.
        DO.
          READ LINE SY-INDEX.
          IF SY-SUBRC <> 0. EXIT. ENDIF.
          IF SY-LISEL+0(1) = 'X'.
            READ TABLE BIKER_TAB INTO BIKER INDEX SY-INDEX.
            APPEND BIKER TO BIKER_SELECTION.
          ENDIF.
        ENDDO.
        CALL METHOD WRITE_LIST.
      ENDMETHOD.
    The public instance method SELECTION can be called by any user of the class containing a reference variable with a reference to an instance of the class. It selects all of the lines in the current list in which the checkbox in the first column is selected. For these lines, the system copies the corresponding reference variables from the table BIKER_TAB into an additional private internal table BIKER_SELECTION. SELECTION then calls the private method WRITE_LIST, which displays the list.
    EXECUTION
      METHOD EXECUTION.
        CHECK NOT BIKER_SELECTION IS INITIAL.
        LOOP AT BIKER_SELECTION INTO BIKER.
          CALL METHOD BIKER->SELECT_ACTION.
          CALL METHOD BIKER->STATUS_LINE IMPORTING LINE = STATUS_LINE.
          MODIFY TABLE STATUS_LIST FROM STATUS_LINE.
        ENDLOOP.
        CALL METHOD WRITE_LIST.
      ENDMETHOD.
    The public instance method EXECUTION can be called by any user of the class containing a reference variable with a reference to an instance of the class. The method calls the two methods SELECT_ACTION and STATUS_LINE for each instance of the class C_BIKER for which there is a reference in the table BIKER_SELECTION. The line of the table STATUS_LIST with the same key as the component ID in the work area STATUS_LINE is overwritten and displayed by the private method WRITE_LIST.
    WRITE_LIST
      METHOD WRITE_LIST.
        SET TITLEBAR 'TIT'.
        SY-LSIND = 0.
        SKIP TO LINE 1.
        POSITION 1.
        LOOP AT STATUS_LIST INTO STATUS_LINE.
          WRITE: / STATUS_LINE-FLAG AS CHECKBOX,
                   STATUS_LINE-TEXT1,
                   STATUS_LINE-ID,
                   STATUS_LINE-TEXT2,
                   STATUS_LINE-TEXT3,
                   STATUS_LINE-GEAR,
                   STATUS_LINE-TEXT4,
                   STATUS_LINE-SPEED.
        ENDLOOP.
      ENDMETHOD.
    The private instance method WRITE_LIST can only be called from the methods of the class C_TEAM. It is used to display the private internal table STATUS_LIST on the basic list (SY-LSIND = 0) of the program.
    Methods of Class C_BIKER
    The following methods are implemented in the section
    CLASS C_BIKER IMPLEMENTATION.
    ENDCLASS.
    CONSTRUCTOR
      METHOD CONSTRUCTOR.
        COUNTER = COUNTER + 1.
        ID = COUNTER - MEMBERS * ( TEAM_ID - 1).
        CREATE OBJECT BIKE.
      ENDMETHOD.
    The instance constructor is executed directly after each instance of the class C_BIKER is created. It is used to count the number of instance of C_BIKER in the static attribute COUNTER, and assigns the corresponding number to the instance attribute ID of each instance of the class. The constructor has two input parameters - TEAM_ID and MEMBERS - which you must pass in the CREATE OBJECT statement when you create an instance of C_BIKER.
    The instance constructor also creates an instance of the class C_BICYCLE for each new instance of the class C_BIKER. The reference in the private reference variable BIKE of each instance of C_BIKER points to a corresponding instance of the class C_BICYCLE. No external user can address these instances of the class C_BICYCLE.
    SELECT_ACTION
      METHOD SELECT_ACTION.
        DATA ACTIVITY TYPE I.
        TIT2 = 'Select action for BIKE'.
        TIT2+24(3) = ID.
        CALL SELECTION-SCREEN 200 STARTING AT 5 15.
        CHECK NOT SY-SUBRC GT 0.
        IF GEARUP = 'X' OR GEARDOWN = 'X'.
          IF GEARUP = 'X'.
            ACTIVITY = 1.
          ELSEIF GEARDOWN = 'X'.
            ACTIVITY = -1.
          ENDIF.
        ELSEIF DRIVE = 'X'.
          ACTIVITY = 2.
        ELSEIF STOP = 'X'.
          ACTIVITY = 3.
        ENDIF.
        CALL METHOD BIKER_ACTION( ACTIVITY).
      ENDMETHOD.
    The public instance method SELECT_ACTION can be called by any user of the class containing a reference variable with a reference to an instance of the class. The method calls the selection screen 200 and analyzes the user input. After this, it calls the private method BIKER_ACTION of the same class. The method call uses the shortened form to pass the actual parameter ACTIVITY to the formal parameter ACTION.
    BIKER_ACTION
      METHOD BIKER_ACTION.
        CASE ACTION.
          WHEN -1 OR 1.
            CALL METHOD BIKE->CHANGE_GEAR
                              EXPORTING CHANGE = ACTION
                              RECEIVING GEAR = GEAR_STATUS
                              EXCEPTIONS GEAR_MAX = 1
                                         GEAR_MIN = 2.
            CASE SY-SUBRC.
              WHEN 1.
                MESSAGE I315(AT) WITH 'BIKE' ID
                                      ' is already at maximal gear!'.
              WHEN 2.
                MESSAGE I315(AT) WITH 'BIKE' ID
                                      ' is already at minimal gear!'.
            ENDCASE.
          WHEN 2.
            CALL METHOD BIKE->DRIVE IMPORTING VELOCITY = SPEED_STATUS.
          WHEN 3.
            CALL METHOD BIKE->STOP IMPORTING VELOCITY = SPEED_STATUS.
        ENDCASE.
      ENDMETHOD.
    The private instance method BIKER_ACTION can only be called from the methods of the class C_BIKER. The method calls other methods in the instance of the class C_BICYCLE to which the reference in the reference variable BIKE is pointing, depending on the value in the input parameter ACTION.
    STATUS_LINE
      METHOD STATUS_LINE.
        LINE-FLAG = SPACE.
        LINE-TEXT1 = 'Biker'.
        LINE-ID = ID.
        LINE-TEXT2 = 'Status:'.
        LINE-TEXT3 = 'Gear = '.
        LINE-GEAR  = GEAR_STATUS.
        LINE-TEXT4 = 'Speed = '.
        LINE-SPEED = SPEED_STATUS.
      ENDMETHOD.
    The public instance method STATUS_LINE can be called by any user of the class containing a reference variable with a reference to an instance of the class. It fills the structured output parameter LINE with the current attribute values of the corresponding instance.
    Methods of Class C_BICYCLE
    The following methods are implemented in the section
    CLASS C_BICYCLE IMPLEMENTATION.
    ENDCLASS.
    DRIVE
      METHOD DRIVE.
        SPEED = SPEED  + GEAR * 10.
        VELOCITY = SPEED.
      ENDMETHOD.
    The public instance method DRIVE can be called by any user of the class containing a reference variable with a reference to an instance of the class. The method changes the value of the private attribute SPEED and passes it to the caller using the output parameter VELOCITY.
    STOP
      METHOD STOP.
        SPEED = 0.
        VELOCITY = SPEED.
      ENDMETHOD.
    The public instance method STOP can be called by any user of the class containing a reference variable with a reference to an instance of the class. The method changes the value of the private attribute SPEED and passes it to the caller using the output parameter VELOCITY.
    CHANGE_GEAR
      METHOD CHANGE_GEAR.
        GEAR = ME->GEAR.
        GEAR = GEAR + CHANGE.
        IF GEAR GT MAX_GEAR.
          GEAR = MAX_GEAR.
          RAISE GEAR_MAX.
        ELSEIF GEAR LT MIN_GEAR.
          GEAR = MIN_GEAR.
          RAISE GEAR_MIN.
        ENDIF.
        ME->GEAR = GEAR.
      ENDMETHOD.
    The public instance method CHANGE_GEAR can be called by any user of the class containing a reference variable with a reference to an instance of the class. The method changes the value of the private attribute GEAR. Since the formal parameter with the same name obscures the attribute in the method, the attribute has to be addressed using the self-reference ME->GEAR.
    Using the Classes in a Program
    The following program shows how the above classes can be used in a program. The declarations of the selection screens and local classes, and the implementations of the methods must also be a part of the program.

    The program contains three class reference variables that refer to the class C_TEAM. It creates three objects from the class, to which the references in the reference variables then point. In each object, it calls the method CREATE_TEAM. The method CLASS_CONSTRUCTOR of class C_TEAM is executed before the first of the objects is created. The status TEAMLIST for the basic list allows the user to choose one of four functions:
    When the user chooses a function, the event AT USER-COMMAND is triggered and public methods are called in one of the three instances of C_TEAM, depending on the user’s choice. The user can change the state of an object by selecting the corresponding line in the status list.

    HI
    <b>1. what is abstract class.</b>
    Abstract classes are normally used as an incomplete blueprint for concrete (that is, non-abstract) subclasses, for example to define a uniform interface.
    Classes with at least one abstract method are themselves abstract.
    Static methods and constructors cannot be abstract.
    You can specify the class of the instance to be created explicitly: CREATE OBJECT <RefToAbstractClass> TYPE <NonAbstractSubclassName>.
    Abstarct classes themselves can’t be instantiated ( althrough their subclasses can)
    Reference to abstract classes can refer to instance of subclass
    Abstract (instance) methods are difined in the class , but not implemented
    They must be redefined in subclasses
    CLASS LC1 DEFINAITION ABSTARCT
    PUBLIC SECTION
    METHODS ESTIMATE ABSTARCT IMPORTING…
    ENDCLASS.
    <b>2. give me some example program using inheritance.</b>
    The following simple example shows the principle of inheritance within ABAP Objects. It is based on the Simple Introduction to Classes. A new class counter_ten inherits from the existing class counter.
    REPORT demo_inheritance.
    CLASS counter DEFINITION.
      PUBLIC SECTION.
        METHODS: set IMPORTING value(set_value) TYPE i,
                 increment,
                 get EXPORTING value(get_value) TYPE i.
       PROTECTED SECTION .
        DATA count TYPE i.
    ENDCLASS.
    CLASS counter IMPLEMENTATION.
      METHOD set.
        count = set_value.
      ENDMETHOD.
      METHOD increment.
        ADD 1 TO count.
      ENDMETHOD.
      METHOD get.
        get_value = count.
      ENDMETHOD.
    ENDCLASS.
    CLASS counter_ten DEFINITION INHERITING FROM counter.
      PUBLIC SECTION.
        METHODS increment REDEFINITION .
        DATA count_ten.
    ENDCLASS.
    CLASS counter_ten IMPLEMENTATION.
      METHOD increment.
        DATA modulo TYPE I.
         CALL METHOD super->increment .
        write / count.
        modulo = count mod 10.
        IF modulo = 0.
          count_ten = count_ten + 1.
          write count_ten.
        ENDIF.
      ENDMETHOD.
    ENDCLASS.
    DATA: count TYPE REF TO counter,
          number TYPE i VALUE 5.
    START-OF-SELECTION.
       CREATE OBJECT count TYPE counter_ten .
      CALL METHOD count->set EXPORTING set_value = number.
      DO 20 TIMES.
        CALL METHOD count->increment.
      ENDDO.
    The class COUNTER_TEN is derived from COUNTER. It redefines the method INCREMENT. To do this, you must change the visibility of the COUNT attribute from PRIVATE to PROTECTED. The redefined method calls the obscured method of the superclass using the pseudoreference SUPER->. The redefined method is a specialization of the inherited method.
    The example instantiates the subclass. The reference variable pointing to it has the type of the superclass. When the INCREMENT method is called using the superclass reference, the system executes the redefined method from the subclass.
    <b>3. Some sample programs using events.</b>
    Events in ABAP Objects - Example
    The following example shows how to declare, call, and handle events in ABAP Objects.
    Overview
    This object works with the interactive list displayed below. Each user interaction triggers an event in ABAP Objects. The list and its data is created in the class C_LIST. There is a class STATUS for processing user actions. It triggers an event BUTTON_CLICKED in the AT USER-COMMAND event. The event is handled in the class C_LIST. It contains an object of the class C_SHIP or C_TRUCK for each line of the list. Both of these classes implement the interface I_VEHICLE. Whenever the speed of one of these objects changes, the event SPEED_CHANGE is triggered. The class C_LIST reacts to this and updates the list.
    Constraints
    The ABAP statements used for list processing are not yet fully available in ABAP Objects. However, to produce a simple test output, you can use the following statements:
    WRITE [AT] /<offset>(<length>) <f>
    ULINE
    SKIP
    NEW-LINE
    Note: The behavior of formatting and interactive list functions in their current state are not guaranteed. Incompatible changes could occur in a future release.
    Declarations
    This example is implemented using local interfaces and classes. Below are the declarations of the interfaces and classes:
    Interface and Class declarations
    INTERFACE I_VEHICLE.
      DATA     MAX_SPEED TYPE I.
      EVENTS SPEED_CHANGE EXPORTING VALUE(NEW_SPEED) TYPE I.
      METHODS: DRIVE,
               STOP.
    ENDINTERFACE.
    CLASS C_SHIP DEFINITION.
      PUBLIC SECTION.
      METHODS CONSTRUCTOR.
      INTERFACES I_VEHICLE.
      PRIVATE SECTION.
      ALIASES MAX FOR I_VEHICLE~MAX_SPEED.
      DATA SHIP_SPEED TYPE I.
    ENDCLASS.
    CLASS C_TRUCK DEFINITION.
      PUBLIC SECTION.
      METHODS CONSTRUCTOR.
      INTERFACES I_VEHICLE.
      PRIVATE SECTION.
      ALIASES MAX FOR I_VEHICLE~MAX_SPEED.
      DATA TRUCK_SPEED TYPE I.
    ENDCLASS.
    CLASS STATUS DEFINITION.
      PUBLIC SECTION.
       CLASS-EVENTS BUTTON_CLICKED EXPORTING VALUE(FCODE) LIKE SY-UCOMM.
      CLASS-METHODS: CLASS_CONSTRUCTOR,
                    USER_ACTION.
    ENDCLASS.
    CLASS C_LIST DEFINITION.
      PUBLIC SECTION.
      METHODS: FCODE_HANDLER FOR EVENT BUTTON_CLICKED OF STATUS
                                 IMPORTING FCODE,
               LIST_CHANGE   FOR EVENT SPEED_CHANGE OF I_VEHICLE
                                 IMPORTING NEW_SPEED,
               LIST_OUTPUT.
      PRIVATE SECTION.
      DATA: ID TYPE I,
            REF_SHIP  TYPE REF TO C_SHIP,
            REF_TRUCK TYPE REF TO C_TRUCK,
            BEGIN OF LINE,
              ID TYPE I,
              FLAG,
              IREF  TYPE REF TO I_VEHICLE,
              SPEED TYPE I,
            END OF LINE,
            LIST LIKE SORTED TABLE OF LINE WITH UNIQUE KEY ID.
    ENDCLASS.
    The following events are declared in the example:
    The instance event SPEED_CHANGE in the interface I_VEHICLE
    The static event BUTTON_CLICKED in the class STATUS.
    The class C_LIST contains event handler methods for both events.
    Note that the class STATUS does not have any attributes, and therefore only works with static methods and events.
    Implementations
    Below are the implementations of the methods of the above classes:

            LINE-IREF = REF_TRUCK.
            APPEND LINE TO LIST.
          WHEN 'DRIVE'.
            CHECK SY-LILLI > 0.
            READ TABLE LIST INDEX SY-LILLI INTO LINE.
            CALL METHOD LINE-IREF->DRIVE.
          WHEN 'STOP'.
            LOOP AT LIST INTO LINE.
              CALL METHOD LINE-IREF->STOP.
            ENDLOOP.
          WHEN 'CANCEL'.
            LEAVE PROGRAM.
        ENDCASE.
        CALL METHOD LIST_OUTPUT.
      ENDMETHOD.
      METHOD LIST_CHANGE .
        LINE-SPEED = NEW_SPEED.
        MODIFY TABLE LIST FROM LINE.
      ENDMETHOD.
      METHOD LIST_OUTPUT.
        SY-LSIND = 0.
        SET TITLEBAR 'TIT'.
        LOOP AT LIST INTO LINE.
          IF LINE-FLAG = 'C'.
            WRITE / ICON_WS_SHIP AS ICON.
          ELSEIF LINE-FLAG = 'T'.
            WRITE / ICON_WS_TRUCK AS ICON.
          ENDIF.
          WRITE: 'Speed = ', LINE-SPEED.
        ENDLOOP.
      ENDMETHOD.
    ENDCLASS.
    The static method USER_ACTION of the class STATUS triggers the static event BUTTON_CLICKED. The instance methods I_VEHICLEDRIVE and I_VEHICLESTOP trigger the instance event I_VEHICLE~SPEED_CHANGE in the classes C_SHIP and C_TRUCK.
    Using the Classes in a Program
    The following program uses the above classes:
    REPORT OO_EVENTS_DEMO NO STANDARD PAGE HEADING.
    Global data of program
    DATA LIST TYPE REF TO C_LIST.
    Program events
    START-OF-SELECTION.
      CREATE OBJECT LIST.
      SET HANDLER: LIST->FCODE_HANDLER,
                  LIST->LIST_CHANGE FOR ALL INSTANCES.
    AT USER-COMMAND.
      CALL METHOD STATUS=>USER_ACTION.
    The program creates an object of the class C_LIST and registers the event handler method FCODE_HANDLER of the object for the class event BUTTON_CLICKED, and the event handler method LIST_CHANGE for the event SPEED_CHANGE of all instances that implement the interface I_VEHICLE.
    <b>4. Narrow casting & wide casting.. And describe the use of it.</b>
    <b>Narrowing Cast</b>
    The assignment of a subclass instance to a reference variable of the type "reference to superclass" is described as a narrowing cast, because you are switching from a more detailed view to a one with less detail.
    Description up-cast is also used.
    <b>use</b>
    A user who is not interested in the finer points of cars, trucks, and busses (but only, for example, in the fuel consumption and tank gauge) does not need to know about them. This user only wants and needs to work with (references to) the lcl_vehicle class. However, in order to allow the user to work with cars, busses, or trucks, you generally need a narrowing cast.
    <b>Widening cast</b>
    The widening cast logically represents the opposite of the narrowing cast. The widening cast cannot be checked statically, only at runtime. The Cast Operator ?= (or the equivalent MOVE ... ?TO … ) must be used to make this visible.
    It changes from a less detailed view to one with more detail.
    <b>use</b>
    The client, the car rental company  wants to execute a function for specific vehicles form the list (vehicle_list).  For example, the client wants to ascertain the truck with the largest cargo capacity.  However, not all vehicles are in the trucks list, it also includes references to cars and busses.
    <b>5. How to declare internal table in ABAP OOPS.</b>
    BEGIN OF LINE,
              ID TYPE I,
              FLAG,
              IREF  TYPE REF TO I_VEHICLE,
              SPEED TYPE I,
            END OF LINE,
    <b>6. What is the use of table type.?</b>
    Please check the SAP help , as all these things are provided in detail in it .
    In case you find it difficult to find it or search for it here is the link
    http://help.sap.com/saphelp_nw04/helpdata/en/90/8d7304b1af11d194f600a0c929b3c3/frameset.htm
    <b>7. What is instance.?</b>
    Instance methods are called using CALL METHOD <reference>-><instance_method>.
    Static methods (also referred to as class methods) are called using CALL METHOD <classname>=><class_method>.
    If you are calling a static method from within the class, you can omit the class name.
    You access instance attributes using <instance>-><instance_attribute>
    <b>8. Explain friend class.</b>
    In rare cases, classes have to work together so closely that they need access to their protected and private components. To avoid making these components available to all users, there is the concept of friendship between classes.
    To do this you use the FRIENDS additions to the CLASS statement, in which all classes and interfaces that are to be provided friendship are listed
    In principle, providing friendship is one-sided: A class providing friendship is not automatically a friend of its friends. If a class providing friendship wants to access the non-public components of a friend, this friend has to explicitly provide friendship to it.
    Classes that inherit from friends and interfaces that contain a friend as a component interface also become friends. However, providing friendship, unlike the attribute of being a friend, is not inherited. A friend of a superclass is therefore not automatically a friend of its subclasses.

  • How to Create an XML using Abap Objects

    Hi there,
    who has an example how to create an XML Document from an internal table using abap objects
    e.g. Class CL_XML_DOCUMENT_BASE ?
    any feedback is welcome.
    thanks
    Johann

    Hi Johann,
    You don't need a class to do the job if you are on a 6.10 or higher system. Use command CALL TRANSFORMATION to create an XML from an internal table.

  • ALV Tree using ABAP Objects

    Can anyone tell me how to Copy a node on an ALV Tree using context menu ?

    Hello Vidya
    The sample report ZUS_SDN_ALVTREE_CTXMENU demonstrates how to copy nodes on an ALV tree.
    Before showing the entire coding I would like to point out a few crucial parts of the coding:
