Error accessing constnt public attribute of a class in an overwrite method.

Hi Gurus,
I am facing an error while accessing a constant public attribute while using it in the overwrite-exit of a methods.
The constant which is declared as public in the attribute section of the class is not available in the overwrite-exit of the method.
Please suggest me how to access the public attributes in the overwtire exits of the methods.
Thanks.

Hi Ramneek,
Let me explain you the entire scenario:
Actually we are trying to ehance the SAP standard class : CL_FITV_POWL_FEEDER_TRIPS in ECC 6.0 EHP 5 .
We tried to create and overwrite-exit of the method "IF_POWL_FEEDER~GET_ACTIONS".
Overwrite-exit of a method is just like a method which will be called instead of the standard method : IF_POWL_FEEDER~GET_ACTIONS.
But the problem which we are facing here is that the Attributes which are defined in the class CL_FITV_POWL_FEEDER_TRIPS, are getting accessed from the overwrite-exit method.
Becuase of this we are not able to implement our custom logic.

Trying to access a private attribute of a class in the same package

Hi,
I have defined a private attribute in a class
class Sample {
     private String newString = "hello";
in another class I am trying to access newString attribute using reflection api. It is throwing hte following exception
java.lang.NoSuchFieldException: value
     at java.lang.Class.getDeclaredField(Unknown Source)
     at refletionpack.mainclass.main(mainclass.java:20)
any ideas how to do it exactly? Should stringclass.getDeclaredField("value")
have the field name(newString) as a parameter?
public class mainclass {
     static Class stringclass = Sample.class;
     static Field stringCharsField = null;
     public static void main(String args[]){
          try{
               stringCharsField = stringclass.getDeclaredField("value");
               stringCharsField.setAccessible(true);
               char[] stringChars = (char[])stringCharsField.get("newString");
               System.out.println(stringChars);
          }catch(NoSuchFieldException ex){
               ex.printStackTrace();
          }catch(IllegalAccessException ex){
               ex.printStackTrace();
}

Hi,
to obtain the value of your private attribute you have to change two lines of code. At first you have to tell your class and not the field that private attributes can be accessed by using stringClass.setAccessible(true);After that you have to specify the name of the attribute to obtain which is called newString in your class which results in
stringCharsField = stringClass.getDeclaredField("newString");For the invocation of the method get(Object) you need an object first that is an instance of the analyzed class by calling Object sample = stringClass.newInstance.
Then you can retrieve the actual data of the requested field by calling String string = (String) stringCharsField.get(sample);A simpler solution would be when you make your attribute newString static. Then you can omit the necessary object for the retrieval of the attribute data and the line would result in String string = (String) stringCharsField.get(null);.
For further issues considering reflection you should read the appropriate API.
Hope it helps.

Accessing a public array from extra class.

I am trying to access a public array that I declared in my main class from a separate class. I am a bit confused about why this is not working.

Accessing the attributes of a class using field symbols?

An option to pulll a variable into a user exit that otherwise would be out of reach is detailed [here|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/208811b0-00b2-2910-c5ac-dd2c7c50c8e8]
Can a similar approach involving field symbols or otherwise, be used to pull in the attributes of a class into the exit? For now, I'm trying to access the A_FRONTEND_INDEX attribute of the class CL_HRXSS_REM.
any ideas?
~Suresh

Hi,
Have you already tried (PROGRAM)(OBJECT)->A_FRONTEND_INDEX in your code? I prepared small testing scenario with two programs and it works.
REPORT zmv_test1.
FORM test.
FIELD-SYMBOLS: <fs> TYPE ANY.
ASSIGN '(ZMV_TEST2)zip->crc32_map' TO <fs>.
IF sy-subrc EQ 0.
<fs> = 'Test'.
ENDIF.
ENDFORM. "test
REPORT zmv_test2.
DATA: zip TYPE REF TO cl_abap_zip.
START-OF-SELECTION.
CREATE OBJECT zip.
PERFORM test IN PROGRAM zmv_test1.
Cheers,

How to access Instance Attribute in a Class Interface from FM ?

Hi Experts
I have the following function module code, that passes the syntax, however in the class interface ABC, I have an attribute IJK that is Instance Attribute (Public). When I modify the code like ABC->IJK but it does not like it, the error is :-
Field "ABC" is unknown. It is neither in one of the specified tables nor defined by a "DATA" statement. "DATA" statement.
Question : How do I declare the Class Interface ABC in my Function Module that will allow me to access the Instance Attribute ?
Thanks in advance.
FUNCTION XYZ.
if not ABC=>EFG is initial.
output = ABC=>EFG.
shift output left deleting LEADING space.
endif.
ENDFUNCTION.

Hello
You question only makes sense if
(1) the class / interface is part of the FM's interface (i.e. an IMPORTING - or perhaps CHANGING - parameter)
(2) the class / interface is defined as global variable in the TOP include of the function group
If either of these two options is applicable then the coding may look like this:
" (1) IMPORTING parameter: e.g. IO_INSTANCE TYPE REF TO class / interface name
IF ( io_instance IS BOUND ).
io_instance->abc = 'New value'.
ENDIF.
" (2) Global variable of function group, e.g. GO_INSTANCE TYPE REF TO class / interface name:
IF ( go_instance IS BOUND ).
go_instance->abc = 'New value'.
ENDIF.
Obviously, the public attribute ABC must be changeable (i.e. not READ-ONLY).

Accessing a public variable between classes

Hi there,
I've got two classes running...one is a document class (EgoGame.as) and another is a class linked to several similar movie clips (Ball.as).
I'm trying to access a public variable from Ball.as which has been declared in the doucment class EgoGame.as.
When I run the test the outputs states the following...
1120: Access of undefined property _ballPlaced.

every place you have a ball reference you can access the lockBall() method. so, if ball0_mc is a Ball class member, you can use:

OOABAP-How to access the protected methos from a class

How to access the protected methos from a class..There is a built in class..For tht class i have created a object..
Built in class name : CL_GUI_TEXTEDIT
method : LIMIT_TEXT.
How to access this..help me with code

hi,
If inheritance is used properly, it provides a significantly better structure, as common components only
need to be stored once centrally (in the superclass) and are then automatically available to subclasses.
Subclasses also profit immediately from changes (although the changes can also render them invalid!).
Inheritance provides very strong links between the superclass and the subclass. The subclass must
possess detailed knowledge of the implementation of the superclass, particularly for redefinition, but also in
order to use inherited components.
Even if, technically, the superclass does not know its subclasses, the
subclass often makes additional requirements of the superclass, for example, because a subclass needs
certain protected components or because implementation details in the superclass need to be changed in
the subclass in order to redefine methods.
The basic reason is that the developer of a (super)class cannot
normally predict all the requirements that subclasses will later need to make of the superclass.
Inheritance provides an extension of the visibility concept: there are protected components. The visibility of
these components lies between that of the public components (visible to all users, all subclasses, and the class itself), and private (visible only to the class itself). Protected components are visible to and can be used by all subclasses and the class itself.
Subclasses cannot access the private components particularly attributes) of the superclass. Private
components are genuinely private. This is particularly important if a (super)class needs to make local
enhancements to handle errors: it can use private components to do this without knowing or invalidating
subclasses.
Create your class inse24 and inherit this CL_GUI_TEXTEDIT
class in yours. You can then access the protected methods.
Hope this is helpful, <REMOVED BY MODERATOR>

Error While creating Security Attributes (QueryFilterPlugin)

Hi,
I am developing a QueryFilterPlugin. For this I need to define security attributes over documents fetched from remote repository(during crawl time). When I try to create a security attribute from an instance of DocumentAcl using method addSecurityAttribute("", "") I get following ProcessingException
EQG-31202: Security attribute not allowed in identity-based access control crawl.
What configurations should exist on SES before creating a security attribute.
Need help
Regards,
Shakti

Sorry about the delay in getting an answer on this...

It seems that your crawler manager class has to implement the "UserDefinedSecurityModel" interface. If it does that, then it will run in attribute-based security mode, whereas if it doesn't it will run in identity-based security mode.

So the declaration for your manager will look something like this:

 
public class MyCrawlerMgr implements CrawlerPluginManager, UserDefinedSecurityModel 
{ 
... 
} 

See: javadoc

I raised doc bug 6666752 for this issue, since it's not at all well documented. Our apologies for the difficulty this has caused you!

i have created a attribute mo_ch_instance of type YSRM70CL_CH_SW_MD where YSRM70CL_CH_SW_MD is the class which has the create_manufacturer method that i am using in my code.
Kindly let me know whats the issue.

Hi,
if   wd_this->mo_ch_instance is not initial.
CALL METHOD wd_this->mo_ch_instance->create_manufacturer

gi_manufacturer = ls_manufacturer
IMPORTING
lv_message = lv_status
endif.
Check wether you have created the object for that class r not.

When you write
class C
    var v;
you are defining a variable that lives inside each instance of C. In other words, you can write code like
var c:C = new C();
c.v = 1;
If you don't have an instance, you can't access v.
When you write
class C
    static var v;
you are defining a variable that lives inside the class itself, and you can access it without having an instance.
