ABAP Objects: Calling private Methods

Hi,
i would choose an private Method of an global class (for example class: CL_GUI_ALV_GRID private Method: SEARCH_START) in a local class.
class lcl_test definition for testing.
private section.
    methods test for testing.
data ref_alv type ref to cl_gui_alv_grid.
endclass.
class lcl_test implementation.
method for test.
    create object ref_alv ...
* How to call a private Method?
call method ref_alv->search_start( ). "not possible!
endmethod.
endclass.
Is this possible?
Regards,
Damir

Damir, of course you can call a private method of a class, if this class has made you a friend with the syntax element FRIENDS (available since Release 6.10). Here is a syntactically correct example, when my_method is a private class method:
REPORT test.
CLASS mytest DEFINITION FOR TESTING.
PRIVATE SECTION.
    METHODS test FOR TESTING.
ENDCLASS.
CLASS myclass DEFINITION FRIENDS mytest.
PUBLIC SECTION.
    CLASS-METHODS my_method.
ENDCLASS.
CLASS myclass IMPLEMENTATION.
METHOD my_method.
ENDMETHOD.
ENDCLASS.
CLASS mytest IMPLEMENTATION.
METHOD test.
    CALL METHOD myclass=>my_method.
ENDMETHOD.
ENDCLASS.
If my_method is not a class method, then you need to create an object of the class first, whose methods you want to test.
Kind regards,
Michael Kraemer

How to call a private method in a JFrame

I have a Frame which has some properties like its size, bgcolor plus other parameters, as instance variables. There is a button on the Frame with the caption : "set properties". When one clicks on that button, a new frame should appear via which a user can change the values of the parameters of the main Frame (i.e size, bgcolor,..etc). The user would input the new values in the textfields or radio buttons that are on the new frame, and then click a submit button, which has to exist on the same NFrame. How can I do that so that when the submit button is pressed, the parameters values are updated and so is the display view ?
I made it this way : I created 2 classes, the main frame and the new Frame. I made the new Frame an instance variable of the main Frame. When the user clicks the " set properties" button on the main Frame, the new Frame is shown. The user enters new values for some of the parameters and clicks submit. The parameters in the new Frame are updated. UP TO HERE EVERYTHING WENT JUST FINE. Now, there is a private method in the main frame that changes the color, size, ...etc of the main frame according to the values stored in the instance variables color, size,...etc. THE QUESTION IS: How can the new Frame display the changes after the values have been updated ? That is, how can it call the "private" method in the main class?? Should the new class be a child class of the main class to be able to access it's private methods ??

Error while usind Private Method of a global class

HI All..
I created a global class (ZLINE_GLOBAL) which has TOT_DATA private method. I have to call this private method in my report, I know that using Friend class we can do this.
But it is not working and showing the same error " METHOD "TOT_DATA" is unknown or Private or Public..

Hi Murthy,
Replace TOT_DATA with M2, you do not have any method by name "TOT_DATA" in your code.

Creation of a static class with private methods

I'm new to java programming and am working on a project where I need to have a static class that does a postage calculation that must contain 2 private methods, one for first class and one for priority mail. I can't seem to figure out how to get the weight into the class to do the calculations or how to call the two private methods so that when one of my other classes calls on this class, it retrieves the correct postage. I've got all my other classes working correct and retrieving the information required. I need to use the weight from another class and return a "double". Help!!!

Issue with CHECK_CHANGED_DATA method of CL_GUI_ALV_GRID class

HI,
I want to check whether my grid has any changes or not, for that i am using the CHECK_CHANGED_DATA method of CL_GUI_ALV_GRID class,
What i am doing is.... I am doing some changes in my grid data and clicking on SAVE . This time CHECK_CHANGED_DATA is saying the grid have changes ,and i am displaying a pop up whether to save the changes or not. And i am saving changes.
Till now Fine.
If i click on SAVE again CHECK_CHANGED_DATA is showing again the Grid has changes.
So how can i solve this problem.
Thanks in advance.

Hello Narendra
If you do not need to do any validations of the changed ALV list data then you can use a very simple approach which does not even require an event handler for event DATA_CHANGED.
The crucial part of the coding is shown below, followed by the entire sample report ZUS_SDN_ALV_EDITABLE_1A. Basically, the ALV list is stored as a "PBO" image of the data (GT_OUTTAB_PBO). And only if the user changed the data (i.e. GT_OUTTAB_PBO <> GT_OUTTAB) the save option including the popup is executed.

Private methods Importing parameter cannot be changed error

Hi Guys,
I have this scenario where I have a private method inside a class which is having an error "Field SAPMF02K cannot be changed".
here is the code for the private method call.
    call method create_bdc_dynpro
         importing IM_PROGRAM = 'SAPMF02K'
                    IM_DYNPRO = '0100'.
code of the method
data: wa_bdcdata type bdcdata.
CLEAR wa_bdcdata.
wa_bdcdata-program = im_program.
wa_bdcdata-dynpro = im_dynpro.
wa_bdcdata-dynbegin = at_true.
APPEND wa_bdcdata to at_bdcdata.
Hope you can help
Thanks!

Howdy,
I think you have your importing/exporting the wrong way round.
The method call should be:
call method create_bdc_dynpro
exporting IM_PROGRAM = 'SAPMF02K'
IM_DYNPRO = '0100'.
And of course in the method definition they should be importing parameters.
Cheers
Alex

Extending classes with private methods?

my understanding of extending classes is that you gain all the functions and methods of that class thus You could over ride any one of them. How ever I am confused on weather or not you inherit and can over ride private methods of the class you are extending or if you have to have all methods public in an extended class.
hope that makes sense, an example can bee seen bellow.
package
     public class Class1
          public function apples():void
               //some code
          private fnctuin bananas():void
               //more code
package
     public class Class2 extends Class 1
          override public function apples():void
               //i changed code
          //can I over ride bananas?

you can only override methods that would be inherited. a private method won't be inherited:

UnusedPrivateMethod - bug when using static private method?

Hi,
I get the following violation:UnusedPrivateMethod. This private method (createDefaultSolidColors) does not seem to be used.
For the foloowing code snippet:
private static const defaultSolidColors:Array = createDefaultSolidColors();
private static function createDefaultSolidColors():Array {
     var _a:Array = new Array();
     for each (var color:uint in defaultColors) {          _a.push(
new SolidColor(color, 0.8));     }
     return _a;}
Why is it a violation? the function is used by the defaultSolidColors property.
Is it a bug or am I missing something?
Thanks,
-ilan

This is a known issue, which has been fixed on trunk.
The fix will be in the next release:

Call Enterprise Bean (or Database) from private Method in Session-Bean

Hi Everybody,
I've a question regarding the possibility to call an dependency injected EJB in an private method of a session bean.
Imagine the following.
@Stateless
public class SomeBean implements SomeLocal{
   @EJB
   private AnotherLocal anotherBean;
   /** Will be called from a web-app via delegate layer */
   @TransactionAttribute(TransactionAttribute.RequiresNew)
   public void someBusisnessMethod(){
       String something = this.getSomeThing();
       //Do more
   private String getSomeThing(){
      return anotherBean.aMethodWhichCallsTheEntityManager();
}I've to refactor code with uses such Call-Hierachy and I want to know whether this is a correct way? Somebody told me that such stuff should not be made, and I quess he told me an explanation, why not to do such stuff, but unfortunally I've forgotten that. Do someone have a suggestion why not to do this? Could it blow the application to hell? Is there any difference to the following code (The way I would have done it)?
@Stateless
public class SomeBean implements SomeLocal{
   @EJB
   private AnotherLocal anotherBean;
    @Resource
    private SessionContext sessionContext;
   /** Will be called from a web-app via delegate layer */
   @TransactionAttribute(TransactionAttribute.RequiresNew)
   public void someBusisnessMethod(){
       SomeLocal self = this.sessionContext.getBusinessObject(SomeLocal.class);
       String something = self.getSomeThingBusinessMethod();
       //Do more
   @TransactionAttribute(TransactionAttribute.Required)
   public String getSomeThingBusinessMethod(){
      return anotherBean.aMethodWhichCallsTheEntityManager();
}

Found the answer by myself....
Here it is if someone might have the same question:
http://stackoverflow.com/questions/3381002 or if the link may down sometime the content of the answer...
>
The motivation here is that most EJB implementations work on proxies. You wouldn't be too far off in thinking of it as old-school AOP. The business interface is implemented by the EJB container, quite often via a simple java.lang.reflect.Proxy, and this object is handed to everyone in the system who asks for the ejb via @EJB or JNDI lookup.
The proxy is hooked up to the container and all calls on it go directly to the container who will preform security checks, start/stop/suspend transactions, invoke interceptors, etc. etc. and then finally delegate the call to the bean instance -- and of course do any clean up required due to any exceptions thrown -- then finally hand the return value over through the proxy to the caller.
Calling this.foo() directly, or passing 'this' to a caller so they can make direct calls as well, will skip all of that and the container will be effectively cut out of the picture. The 'getBusinessObject(Class)' method allows the bean instance to essentially get a proxy to itself so it can invoke its own methods and make use of the container management services associated with it -- interceptors, transaction management, security enforcement, etc.

How to access private method of an inner class using reflection.

Can somebody tell me that how can i access private method of an inner class using reflection.
There is a scenario like
class A
class B
private fun() {
now i want to use method fun() of an inner class inside third class i.e "class c".
Can i use reflection in someway to access this private method fun() in class c.

I suppose for unit tests, there could be cases when you need to access private methods that you don't want your real code to access.
Reflection with inner classes can be tricky. I tried getting the constructor, but it kept failing until I saw that even though the default constructor is a no-arg, for inner classes that aren't static, apparently the constructor for the inner class itself takes an instance of the outer class as a param.
So here's what it looks like:
 //list of inner classes, if any
 Class[] classlist = A.class.getDeclaredClasses();
 A outer = new A();
 try {
 for (int i =0; i < classlist.length; i++){
 if (! classlist.getSimpleName().equals("B")){
//skip other classes
continue;
//this is what I mention above.
Constructor constr = classlist[i].getDeclaredConstructor(A.class);
constr.setAccessible(true);
Object inner = constr.newInstance(outer);
Method meth = classlist[i].getDeclaredMethod("testMethod");
meth.setAccessible(true);
//the actual method call
meth.invoke(inner);
} catch (Exception e) {
throw new RuntimeException(e);
Good luck, and if you find yourself relying on this too much, it might mean a code redesign.

Error in private methods when implementing a BAdI

Hi,
I implemented a BAdI and added some custom private methods in my implementing class. When I looked at the object list, my private methods are marked with a color red circular shape, which I guess it means those have error. But, when I tried to activate and test the BAdI, it works fine. Any idea why it marks my private methods as error? Am I missing something here?

it denotes Accessibility / Visibility of those methods .

Private method in the comp controller

HI
How do ui declare the private method in the componenet controller and declare the parameter one as the node and other as structure, when i click on methods tab it declears the public method with green logo in the implementation view, while i need to define a private method that should reflect with the red like logo in the outline view , when i click implementation tabr

you can write the private method in hte end of the implementation in the other hooks

Does abap unit testclass can get acces to private methods of classes to tes

Hi,
I want to do a abap unit test inside a user program. the program calls my class and i want some of the methods there to be tested (i.e. db layer, some business logic etc).
My problem is, that I can define unit test very goog on program level or even for public methods of the class.
But what should I do if I want the maybe 3 private methods called by the public method to be tested standalone?
Does anyone have a idea for that?
THX
regards,
Jens

Hello Jens,
you may test private methods with the help of the FRIEND statement. For sample you place a local testclass in the class pool. In order to get friendship you may than use the following sequence of statements.
class ltc_Repository definition deferred.
class cl_Global definition local friends ltc_Repository.
class ltc_Repository                     "#AU Risk Level Harmless
    definition for testing.
    private section.
      methods:
        retrieve_Fails_For_Bad_Key   for testing,
        update_Fails_For_Dup_Key     for testing.
endclass.
or
interface lif_Unit_Test.
endinterface.
class cl_Global definition local friends lif_Unit_Test.
class ltc_Repository                     "#AU Risk Level Harmless
    definition for testing.
    public section.
      interfaces: lif_Unit_Test.
    private section.
      methods:
        retrieve_Fails_For_Bad_Key   for testing,
        update_Fails_For_Dup_Key     for testing.
endclass.
By this technique you can grant access to private members of the global class to any local class. Without exposing something to the outside world! This code can be placed in the local implementation include of the class pool, or in test class include from release 7.02 onwards.
Using transaction /nABAPHELP provides all details on the FRIEND statement.
Testing private methods can be useful but also tends to result in [fragile tests|http://xunitpatterns.com/Fragile%20Test.html]. That means changes to the implementation may make your test turn red without any violation of the outside contract.
