Modify Method in Class

Hi All,
In Txn SE24, we entered CL_OIURV01_RD_DRIVER to modify it. In "Attributes" tab we can edit many attributes but few are disabled and cannot be modified. We need to modify attribute "RD_BOOKINGS" but the Modify Button is disabled. Any suggestion how can we edit it ?
Warm Regards,
-N

Ok, I checked it in another system.
These attributes which don't have typing, have litte green icon on right. When you click on it you will see that this attribute is created not based on Dictionary types but is a structure definition. It has lots of fields.
I think you can't change it because you got acces key to class but there are many dependand objects which are repnsible for accessing its different parts (i.e public section, private etc).
Below a list of objects which you might need access too:

How can i run a special name method of class?

i dynamic created a obj
and i don't know the method of class,
so i use a String parameter as the method's name
but how can i run the method?
please give me a copy of code, thanks!

JVM crash when adding method to class

Hello,
I am getting some kind of problem with the virtual machine. The JVM crashes when making a class (with new). It happened when I was adding some functionality to the class, I worked my way backwards and discovered it crashes when I add any new methods, if I comment them out again everything works, adding a method by any name causes to crash.
I went in debug to find out where it was happening, and it happens on this line:
public PerspectiveActionToolBarHeader createPerspectiveActionToolBarHeader() {
     PerspectiveActionToolBarHeader ret = null;
     ret = new PerspectiveActionToolBarHeader(this); // << here
     return ret;
}The PerspectiveActionToolBarHeader is the class where adding methods causes it to fail. For example, it has the method
public Container getContainer() {
     return this;
}and works, but if I add:
public void anything(){} it causes a crash on the new PerspectiveActionToolBarHeader(this);
When stepped into with the debugger it goes to the (source not found) ClassNotFoundException and eventually before the crash the (stack?) looks like this:
Launcher$AppClassLoader(ClassLoader).loadClass(String) line: not available
MaldiSoftwareOptionsUIEnsemble(PerspectiveUIEnsemble).createPerspectiveActionToolBarHeader() line: 72
and the debugger describes the class just before the crash:
Launcher$AppClassLoader (id=44)
arg0     "saiman.uiobjnew.PerspectiveToolBarButton" (id=51) << has just changed
and the log file (not sure how much to copy here!):

I think I may have stumbled across the answer, It seems that the abstract class PerspectiveToolBar implements
the interface with the method public Container getContainer() but does not declare it, this should be fine because the method is abstract but it crashes. When I add the method public abstract Container getContainer(); to the abstract sub-class there is no error. I'm going to try make a small compilable example to see if I can reproduce it.
edit its actually only one of the two interface methods, and not getContainer(), but another one. If anyone is interested here is the interface:
public interface IMassSpectrometerPassableControlContainer
     Container getContainer();
     void reloadWidgetsOnVisible(boolean visible);
}and it works only if there is "public abstract void reloadWidgetsOnVisible(boolean visible);" in the abstract class PerspectiveToolBar implementing IMassSpectrometerPassableControlContainer.
I tried to reproduce it, but I can't get another class to repeat the behaviour, so I don't think I can post a bug report on it. Here is my attempt anyway:
import javax.swing.JToolBar;
* Class     Test.java
* Date:     7 Jun 2011
* @author     tofuser
public class Test extends Subclass
     public static void main(String args[])
          System.out.println("in main method");
          Test t = new Test();
          t.interfaceMethod();
     @Override
     public void interfaceMethod()
          System.out.println("interface method");
abstract class Subclass extends JToolBar implements Interface
     private static final long serialVersionUID = 1L;
     //this line is where it breaks in my code, including it works
     //public abstract void interfaceMethod();
interface Interface
     public abstract void interfaceMethod();

Creation of Material using BDC Session method & global class

Hi
Creation of Material using BDC Session method & global class by using oops.
can anyone plz help me out

Hi,
it looks like it's not possible to call this BAPI wihtout material number. Here is a quote from BAPI documentation.
When creating material master data, you must transfer the material
number, the material type, and the industry sector to the method. You
must also enter a material description and its language.
Cheers

Internal table in method of class (BADI)

Hello people !!
I need to use an internal table into method of class. I don´t know very well how to use it. I know that it hasn´t a header; but I don´t know how to defined and use it.
I need to use in a method of badi.-
I will be grateful by the help that your could offer to me.-
Thank you so much,
Esther.-

Thank you for your answer.
But, I had defined as de fist item, but I had defined with a structure of dictinary.
Now, in my code, I need to deposit information to the above mentioned table. Then, when I try to accede to the fields of the estructure, when I compile it gives me the following mistake:
"ACC_DATA" is a table without a header line and therefore has no
component called "CUENTA".
I attach departs from the code:
types: es_accdata type standard table of Z_ES_ACCDATA.
data: acc_data type es_accdata.
      loop at it_mseg into r_mseg.
      si es Entrada de Mercancía
        if r_mseg-bwart = '101'.
          at first.
            acc_data-cuenta = r_mseg-sakto.
            if not r_mseg-kostl is initial.
              acc_data-centro_coste = r_mseg-kostl.
            else.
              acc_data-orden_inversion = r_mseg-aufnr.
            endif.
          endat.
          monto = monto + r_mseg-dmbtr.
        endif.
      endloop.
Thank you againg, for a new answer !!!!

Class-data versus data and methods versus class-methods in OO ABAP

Whats is difference between methods and class-methods ?
What is the difference between data and class-data ?

Hi Rajesh,
There are two types of componenets in a class
1)Static components
2) Instance components
Instance components exist for every instance of the class, while static exist only once for any number of instances of the class.
Components of the class are methods, attributes, events etc.
static attributes are represented by CLASS-DATA and instance attributes are represented by DATA.
static methods hence are done by CLASS-METHODS and can access only static attributes.
Instance methods are done by METHODS and can access any attribute.
For eg: supposing that in a class, there is a static attribute. Suppose after one instance is created, we are setting this static attribute value as 10. Now we are creating another instance of the same class. Now when you try to display the value of this attribute, it will be 10.ie. it needs to be initialized once and can be shared between instances.
Just go through this document..You will get nice info from this.

Abstract method and class

I'm a beginner in Java and just learn about abstract method and class.
However, i am wondering what is the point of using abstract method/class?
Because when I delete the abstract method and change the class name to public class XXXX( changed from "abstract class XXXX), my program still runs well, nothing goes different.
Is it because I haven't encountered any situation that abstract method is necessary or ?
Thanks!

Yes - you probably haven't encountered a situation where you need an abstract.
Abstract classes are not designed to do anything on their own. They are designed to provide a template for other classes to extend by inheritance. What you have build sounds like a concrete class - one which you are creating instances of. Abstract classes are not designed to be ever instantiated in their pure form - they act like a partial building block, which you will complete in a class which extends the abstract.
An example might be a button class, which provides some core functionality (like rollover, rollout etc) but has an empty action method which has to be overwritten by a relevant subclass like 'StartButton'. In general, abstract classes may not be the right answer, and many people would argue that it is better to use an interface, which can be implemented instead of extended, meaning that you can ADD instead of REPLACING.
Not sure if that helps.. there are whole chapters in books on this kind of thing, so it's hard to explain in a couple of paragraphs. Do some google searches to find out more about how they work.

Method addTextUrlColumn (Class oracle.jbo.html.databeans)

The method addTextUrlColumn (Class oracle.jbo.html.RowSetBrowser) adds an additional column to the View's RowSet. This column will be appended after all of the colummns that represent attributes belonging to the RowSet. How can I insert a additoinal column before all of the columns of the RowSet instead?
Thanks
Yoo

The RowsetBrowser doesn't support this by default, you have source code to this control. You can extend it's features by adding this capability. Look at the source code in bc4jhtmlsrc.zip

How to avoid restart weblogic after I modify EJB implementation class?

I am sure I redeploy my application after I modify EJB implementation class. It

Quick tutorial of using methods of class

Hi,
I have never use methods of class before. Is there anyone can give me a quick tutorial how to do it?
To be more specific I need convert field 'DAUER' into the required format using one of the following methods of class 'CL_HR_T510_PSRCL':
     CONVERT_DURATION_TO_MMMM: Duration Conversion to Format 'MMMM'
     CONVERT_DURATION_TO_MMMM: Duration Conversion to Format 'YYMM'
Please be more detailed in describing it.
Your help will greatly appreciate.

Hello Veb,
You will find at this sdn page at section ABAP Objects , documentations and links about ABAP OO :

For your example :
1) You can use like this :
CALL METHOD CL_HR_T510_PSRCL=>CONVERT_DURATION_TO_MMMM
EXPORTING
    DURATION = old_duration
RECEIVING
    MMMM     = new_duration.
1) Like this :
l_dauer = convert_duration_to_mmmm(
                             duration = l_dauer).
Best regards

How to pass Method Inner Class reference to other method?

Hi All,
I am trying to pass the reference of "method inner class".
Can any one explain me how to pass the reference and where other method will sit in the class, I mean either in Outer Class or in Inner Class ?
Thanks in advance for ur reply :)
package methosInnerClass;
public class MethodLocalInnerClass {
     private String outerName;
     private static String statOuterName;
     public MethodLocalInnerClass(String name, String statName) {
          outerName = name;
          statOuterName = statName;
     public void methodWithLocallClass() {
          class MethodInnerClass {
               String innerName;

Is it Advicable to modify standard message class?

Hi Experts,
I need a small confirmation.Is modifying standard message class is having any restrictions?
Currently in SE91 message class number 002 i need to modify text .Is it ok to directly do and transport or need to take any extra precautions?
Regards
sas

Hi Thomas,
Thanks for the suggestion.
Actually message class name: HRTIMOOREC.
In that one message always shows what ever leave action is it shows as 'Number of days leave 5. Apply sick leave for HR'.
Requirement is just to remove 'Apply Sick Leave for HR'.
so that it wont confuse the clients who are applying for some other leaves..so request is to just modify
that number 001.
So in general need to modify SAP programs we required Access keys here its not required i guess...
Now Thomas is there any things need to taken care or general Message class how we do the same and Transfer? Thanks
Regards

Why we are making a variable as final in method inner class ?

Why we are making the variable as final (method inner class) while we are accessing the method variable in inner class ?
regards,
namanc

As far as I can tell, the only reason is to protect the programmer: when the inner class instance is constructed, it is given the then-current value of the variable. If the variable (or method parameter) later changes, the value held by the inner class would not. By making the variable final, the programmer doesn't have to worry about them staying in sync.
Here's some code to ponder:
public class InnerExample
    void printMe( final int x )
        Runnable runMe = new Runnable()
            public void run()
                System.out.println(x);
        (new Thread(runMe)).start();
}When compiled with the Sun JDK 1.4.2, you get this bytecode:
void printMe(int);
Code:
   0:   new     #2; //class InnerExample$1
   3:   dup
   4:   aload_0
   5:   iload_1
   6:   invokespecial   #3; //Method InnerExample$1."<init>":(LInnerExample;I)V
   9:   astore_2
   10: new     #4; //class Thread
   13: dup
   14: aload_2
   15: invokespecial   #5; //Method java/lang/Thread."<init>":(Ljava/lang/Runnable;)V
   18: invokevirtual   #6; //Method java/lang/Thread.start:()V
   21: returnAt line (byte) 5, it loads the passed value onto the stack; at line 6, it invokes the inner class constructor (which is created by the compiler). Nothing in this sequence of code would prevent use of a non-final variable.

Pass referance of veriable to method in class

Hi friends,
I am trying to use ABAP object. In that i am trying to use reference variable which is pass to method in class. Whatever the operation perform on that variable should be reflected to original variable at main method.
So how can I do that.

Hi Amit,
U can try it out. Using Pass by Value it is possible for U to access the variable inside the method.
ex:-
DATA : num type i.
CLASS c1 definition.
PUBLIC SECTION.
METHODS : meth1 IMPORTING INPUT1 TYPE I
                              VALUE(INPUT2) TYPE I.
ENDCLASS.                    "c1 DEFINITION
CLASS c1 implementation.
METHOD : meth1.
    " INPUT1 = 2. " input parameters passed by reference cannot be changed within the method
    INPUT2 = 4.
    WRITE : /5 'Input Parameters PASSED BY VALUE alone can be changed inside METHOD : ' ,INPUT1.
ENDMETHOD.
ENDCLASS.                    "c1 IMPLEMENTATION
START-OF-SELECTION.
DATA :oref TYPE ref TO c1.
CREATE OBJECT : oref.
num = 5.
CALL METHOD : oref->meth1 EXPORTING INPUT1 = 3
                                     INPUT2 = num.

Private, protected Access Modifiers with a class

Why cant we use private and protected access modifiers with a class?
Thanks.

Public access allows you to extend a parent class in some other package. If you only want users to extend your class rather than instantiate it directly, make the class abstract and design for extension.Agreed. However, would the same argument be not true for the default access at the class level? No. Default access would only allow you to extend a parent class in the same package (as opposed to some other package).
Now my confusion is why is a class allowed default access at the top level and not protected?Because protected for a top-level class makes no sense. The protected keyword provides member access to any other class in the same package and extending classes outside the package. A top-level class isn't a member of a class, by definition, so there's nothing that protected would do provide differently than public.
So, the two access modifiers for a top-level class are public and default. Public allows access to the class outside the package, whereas default restricts access to the class within the package.
