  • The use of interface in abap object

    hi,
    what is the use of interface in class? can have a simple example with explanation? i have read from help but not quite understand its purpose.
    thanks

    Hi El,
    Interfaces are pure abstract classes. The interface methods will have only definitions but no implementations.
    The classes which will implement interfaces has to provide the implementation to the methods.
    Interfaces will provide the common definition and the classes which implements these interfaces will provide them different implementation to the methods as per their requirements. This achieves Polymorphism of Object Orientation.

  • Interfaces in ABAP Objects

    some body please tell why this code snippet is giving a syntax error

    Try out with this code and let me know if it works.

  • Looking for an ABAP Objects e-learning course

    Does anyone know of any abap objects e-learning courses that are available? I checked with sap university, and they only offer the BC 401 customer course. I'm looking for a course for beginners. I found an advanced course that has been recoreded in Germany, but it is an advanced course for developers with experience in abap objects.  Thanks! Allison McCloskey

  • Hook methods in ABAP Objects

    Hello,
    i discovered that method calling in the class-inheritance of ABAP Objects doesn't work similar to other OO languages.
    Example:
    1 Superclass named "Z_CLASS"
    1 Subclass of "Z_CLASS" named "Z_SUB"
    Z_CLASS defines a method "initialize" and has a constructor which calls "initialize".
    Z_SUB redefines the method "initialize" assigning some values to instance-attributes.
    If i instantiate a new "Z_SUB"-object then the contructor of "Z_CLASS" is called which calls ITS OWN "initialize" not the one of the subclass. For comparison: Java would call the initialize of the subclass.
    I have to implement a constructor in every subclass of "Z_CLASS" which calls the super constructor and the own "initialize" after that to solve this problem. This isn't the proper OO way!
    Did i miss something or am i right?
    Thanks in advance,
    Stefan

  • Overriding attributes in ABAP objects

    Hello,
    I currently want know if it is possible to override attributes in ABAP objects. i know it is possible with methods. I have extend a previous class functionality and want to change the refrence type of an attribute from the parent class, but only on the child. Is this possible in ABAP object or even in normal object oriented techniques.
    Thanks
    Brendan

    Hi,
    ususally you can achive this with other technics. You can e.g. use the class hierarchy for this:
    The attribute is of type REF_SUPERCLASS. Within the superclass it should be working when you set subclasses of REF_SUPERCLASS as attribute.
    Another way is to use interfaces as reference type for your attribute.
    Please refer to [ABAP Objects|http://help.sap.com/saphelp_nw70/helpdata/EN/ce/b518b6513611d194a50000e8353423/frameset.htm]. Especially the chapters about Inheritance and Interfaces.

  • 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?
    Thanks and regards,

  • Throw statement equivalent in ABAP Objects

    Hi All,
    I am trying to raise an exception and use a throw statement after catch inside try endtry in ABAP objects. Later i understood that there is no throw statement defined in ABAP objects. Could anyone help me out to understand the equivalent throw statement in ABAP and how to use in raise exception. I am pasting my code below for reference.
    try.
        CATCH Zxx_EXCEPTION into err.
         write:/ err->local_text.
        message err->LOCAL_TEXT type 'I'.
         if err->local_text = ZIF_XXXX~BUSOBJLOCKED.
          throw CX_AI_APPLICATION_FAULT.
    endtry.
    Thanks

    Hello Deno
    The TRY/CATCH logic of ABAP-OO is pretty much the same like in Java. Instead of throwing exception we have to raise them.
    Method execute somewhere raise an exception of class zcx_myexception.
    method execute.
      if ( condition = abap_true ).
      else.
        RAISE EXCEPTION TYPE zcx_myexception
          EXPORTING
            textid = ...
            <parameter> = ...
      endif.
    endmethod.
    TRY.
      call method go->execute( ).
      CATCH zcx_myexception INTO lo_error.
    * Do error handling
    ENDTRY.
    If the method that calls go->execute does not surround the method call by TRY/CATCH then it must define the exception class in its interface and, thereby, propagate the exception to the next higher level calling method.

    Hi,
    Sending ABAP Objects questions is not an option but normally, your concepts are tested for:
    - Classes and objects
    - Inheritance
    - Casting
    - Interfaces
    - Events
    - Global classes and interfaces
    - Exception handling
    - Dynamic programming
    You can use help.sap.com to take a look at these topics one by one. Hope this helps.
    Good luck.

  • Overloading+ Abap objects

    Hello
    Is overloading possible in abap objects. if so can u pls help me with the sample code.
    regards!
    arun

    hi arun ,
    overloading is not possible in abap objects . Some other object-oriented programming languages permit the overloading offunctions or methods. This means that a separate, changed parameter interface
    can be defined for an overwritten or redefined method. ABAP Objects does not currently support this mechanism.
    Thanks
