How to access a proctected method of a class
Hi All,
I have the below code where in the idents_get is a protected method of the class.so when i activate it is throwing an error, method is unkown or protected or private.
data: gv_class TYPE REF TO /tdag/cpcl_decl_sub_view_ctrl.
create object gv_class.
CALL METHOD gv_class->idents_get
EXPORTING
i_estcat = gc_estcat6
i_pos_wanted = 1
IMPORTING
et_idents = lt_idents
changing
xt_recns = li_recn
EXCEPTIONS
read_failed = 1
others = 2.
i know protected methods can be accessed in derived class.
I'm new to ABAP oops concepts please give me some pointers to access a protected method.
or any sample code to access protected method.
Thanks in advance,
Srilakshmi.
Hello Srilakshmi
You can access protected methods WITHIN an instance of the class or WITHIN an instance of a sub-class.
However, in your case you are calling the method from the report and, therefore, the class must be PUBLIC.

ECATT: How to access a protected method of a class with eCATT?
Hi,
These is a class with a protected method. now i am willing to automate the scenario with eCATT. Since the method is Protected i am unable to use createobj and use callmethod. Could anyone suggest me a work around for this ?
Regards
Amit
Edited by: Amit Kumar on Jan 10, 2012 9:53 AMHello Anil,
You can write ABAP Code to do that inside eCATT Command.
ABAP.
ENDABAP.
Limitation of doing that is you can only use local variable inside ABAP.... ENDABAP. bracket.

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 codehi,
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>

How do you call a method from another class without extending as a parent?
How do you call a method from another class without extending it as a parent? Is this possible?
Why don't you just create an instance of the class?
Car c = new Car();
c.drive("fast");The drive method is in the car class, but as long as the method is public, you can use it anywhere.
Is that what you were asking or am I totally misunderstanding your question?

How to access this.getNewNode() method within addTreeSelectionListener??
Dear friends,
I met anoother problem as follows:
I defined a method called
setNewNode(NewNode nn){
getNewNode(){
return nn;
I tried to make regerence to this method:
this.getNewNode();
if I put this reference this.getNewNode(); outside of following code such as:
this.getNewNode();
tree.addTreeSelectionListener(new TreeSelectionListener() {
everything fine,
but If I put this.getNewNode(); within following code,
so cannot pass compile, get error,
tree.addTreeSelectionListener(new TreeSelectionListener() {
this.getNewNode();
now get error,
How to make a successfule access to this method this.getNewNode() ??
Thanks a lot.
sunny
//this.getNewNode(); // access ok
tree.addTreeSelectionListener(new TreeSelectionListener() {
public void valueChanged(TreeSelectionEvent evt) {
// this.getNewNode(); // error, can not refer to this method.
// Get all nodes whose selection status has changed
TreePath[] paths = evt.getPaths();
// Iterate through all affected nodes
for (int i=0; i<paths.length; i++) {
if (evt.isAddedPath(i)) {
// This node has been selected
} else {
// This node has been deselected
});good point, but it seems that
OuterClassName.this.getNewNode() did not work,
only OuterClassName.getNewNode() is acceptable.
thanksThat indicates you must have made getNewNode() static. Glad it's working though... -

plz help me to solve this problem....
rajkumarThe JSP wil be converted into a java file and then compiled into a class. If you are using tomcat, the java file will be somewhere in the work folder of your tomcat installation. Find the java file and check the line that is reported in the exception to see where the null-pointer is coming from.

How to access the private method
All,
I have class ABC with private method getfilename().
I want to use this private method ...
Is it possible to use this method without inheritence ?
Is it possible to access this private method using annoymous inner class ?
or any other alternatives ??
namancI have class ABC with private method getfilename().
I want to use this private method ... You can't; it's private to the instantiations of that class.
Is it possible to use this method without inheritence ? No, no even with inheritance.
Is it possible to access this private method using
annoymous inner class ? Nope, unless you can write that anonymous inner class yourself.
or any other alternatives ?? Nope; privvy parts are privvy parts and only the owner of those privvy
parts can touch them. (ahem)
kind regards,
Jos
ps. unless you want to do reflection surgery of course. -
How to call a static method in a class if I have just the object?
Hello. I have an abstract class A where I have a static method blah(). I have 2 classes that extend class A called B and C. In both classes I override method blah(). I have an array with objects of type B and C.
For every instance object of the array, I'm trying to call the static method in the corresponding class. For objects of type B I want to call blah() method in B class and for objects of type C I want to call blah() method in C class. I know it's possible to call a static method with the name of the object, too, but for some reason (?) it calls blah() method in class A if I try this.
So my question is: how do I code this? I guess I need to cast to the class name and then call the method with the class name, but I couldn't do it. I tried to use getClass() method to get the class name and it works, but I didn't know what to do from here...
So any help would be appreciated. Thank you.As somebody already said, to get the behavior you
want, make the methods non-static.You all asked me why I need that method to be
static... I'm not surprised to hear this question
because I asked all my friends before posting here,
and all of them asked me this... It's because some
complicated reasons, I doubt it.
the application I'm writing is
quite big...Irrelevant.
Umm... So what you're saying is there is no way to do
this with that method being static? The behavior you describe cannot be obtained with only static methods in Java. You'd have to explicitly determine the class and then explicitly call the correct class' method. -
How to create dynamically a method of a class??
I would like to create dynamically a method of a class. Is this possible?
By means of a report I would like to choose a class, to which the defined method should be added and after that I would like to define the name of the method and its parameters. The result should be, that the method is added to the selected class.
How to do this?
Regards
ChristianChristian,
looks like an interesting development project. Though I share the doubts Rich has.
Anyway, what you could possibly do is, start a runtime analysis for SE24, open an existing class, create a new method including desired interface parameters.
Then analyze it and see what functions/methods are used.
But It might be more complex than expected.

How to access the Swing Conponents in different Classes
Hi
In swing based application, Parent Frame filled with multiple Panels, for each panel i created separate class and added the required swing component.
components in one panel class require to update/modify components in another panel class.
For solving this problem i made the components & required methods in a class as STATIC and directly access from another class.
Is it right approach?
is there any other approach to solve this issue?
Thanks

You already implemented the V(iew)-part.
Now you have to create a M(odel) to hold the Information you want to manipulate and display and a C(ontroller) that changes this information upon the user input (could be combined...)
Usually the display components register themselves as Listeners to the model and the model publishes state changes to who ever has been registered...

How to access complex arrays/types in a class
public class VirusScanMessage {
public byte[] fileContent;
public int fileSize;
public String messages;
public String datLocation;
jclass clazz = env->FindClass("VirusScanMessage");
// get field
jfieldID byteArrayField = env->GetFieldID(clazz,"fileContent","[b");
// get the byteArray object
jbyteArray byteArray = env->GetObjectField(object,byteArrayField);
// get array length
jsize fileContentLength = env->GetArrayLength(byteArray);
jbyte * fileContent = env->GetByteArrayElements(byteArray,0);
// do stuff
// release array
env->ReleaseByteArray(byteArray,fileContent,0);thats the normal way but how to access the arrays if they are complex like this(struct1,class2)?:
public class VirusScanMessage {
public struct1[] fileContent;
public int fileSize;
public String messages;
public String datLocation;
public class2 cl2;
}Note that your code is missing error checking.
thats the normal way but how to access the arrays if they are complex like this(struct1,class2)?:Retrieve each item from the array as an Object.

10.1.3.4 - How to access custom java methods in worklist ?
We want to invoke a custom java method inside of worklist, when the file attachments are added to the worklist. We are planning to modify the auto-generated jsp page to do the same. We have created the custom jar files, but am not sure where to deploy this jar file ? We are not able to compile the jsp /jar. Does anybody have any idea where the custom jar file goes ?
The bpel\samples\hw\worklistapp\readme will explain you about how to do this.
