How to get the name of the class which is currently in use

Hi all,
I have two classes Mother and Child, and I use this code to print the name of the class in use
  DATA m TYPE REF TO zmother.
  DATA class_name type string VALUE 'CHILD'.
  CREATE OBJECT m TYPE (class_name).
  CALL METHOD m->PrintName .
So, what is the source code that I have to put in the PrintName methode?
Thanks.

Ok, but how can I get the name of the object class that calls the methode!
REPORT  ztest_method.
*       CLASS c1 DEFINITION
CLASS c1 DEFINITION.
  PUBLIC SECTION.
    METHODS: get_data.
ENDCLASS.                    "c1 DEFINITION
*       CLASS c1 IMPLEMENTATION
CLASS c1 IMPLEMENTATION.
  METHOD get_data.
****** What is the code to put here to know the name of this Class?*
  ENDMETHOD.                    "get_data
ENDCLASS.                    "c1 IMPLEMENTATION
DATA oref TYPE REF TO object.
DATA: method TYPE string.
DATA: cla_name(20).
START-OF-SELECTION.
  cla_name = 'C1'.
  CREATE OBJECT oref TYPE (cla_name).
  BREAK-POINT.
  CALL METHOD oref->(method).

    Hi Rajeev,
    To retrieve a FilterContainer you will need to traverse the report structure:
    ReportStructure boReportStructure = boDocumentInstance.getStructure();
    ReportContainer boReportContainer = (ReportContainer) boReportStructure.getReportElement(0);
    FilterContainer boFilterContainer = null;
    if (boReportContainer.hasFilter()) {
         boFilterContainer = boReportContainer.getFilter();
    } else {
         boFilterContainer = boReportContainer.createFilter(LogicalOperator.AND);
    Calling boDocumentInstance.getStructure() will retrieve the entire structure for the document.
    Calling boReportStructure.getReportElement(0) will retrieve the structure for the first report of the document.
    Hope this helps.

  • How to get the number of files currently open?

    hi,
    does any one know how to get the number of files currently open in windows OS?
    e.g. lets say .txt files...
    any comment will be really appreciated.
    thanks

    Assuming that you don't want to actually do this from within Java code (which would obviously require native code), here's a utility that will give you a list of which file handles are opened by which processes (on Windows):

  • [CS3][JS] How to get the file type of current document

    Hi,
    How to get the file type of current opening document (e.g., tif, jpeg, png) using JavaScript with Photoshop CS3.
    I am using file object the open the files one by one in the folder (the files sometimes don't have the extensions).
    If the current document is in tiff format then I need to convert to 8-bit, if its an Jpg image then needs to ignore the file.
    Regards,
    Karthik

    Do you really need to know the file type? What about just checking the bit depth?
    var doc = activeDocument;
    if (doc.bitsPerChannel != BitsPerChannelType.EIGHT) {//Not 8 bit
    doc.bitsPerChannel = BitsPerChannelType.EIGHT;
    //do your save etc
    }else{
        //Ignore

    I would also like to know how we get the DOM object ID for particular item.Use firebug or inspect the source code of the rendered page to see the object IDs. Other then then, the typical ID of page items is the name of the item. For regions you can set your own ID.

    Agreed, but IMO, i still feel its best if there is no tie in between consumer class level details and the database it talks to. A service layer is needed in between them.Sounds like you've done a bit of this before. Me, I've either been a modeller/DBA, doling out data, or a nuts and bolts programmer (and actually more toolmaker than apps, but did a bit of that too).
    Do you know of a good book about the "middle ground" (ie, these service layers)? I understand it empirically, but haven't had a lot of exposure to it.

    PS: Apologies. Edited my previous post, presumably while you were composing your reply, when I finally realized what '.filed' meant.Most of my work is in web development, never been a DBA :) . The biggest 'concern' in my shop is 'separation of concerns'. The UI group reports up to a different IT head, the DB group reports up to a different IT head and so on. The looser the coupling between these systems, the lesser the project costs (Integration, QA etc) are. Martin Fowler's books contain good information about separation of concerns in an enterprise environment. The two books which i recommend are
    [url http://www.amazon.com/Patterns-Enterprise-Application-Architecture-Martin/dp/0321127420]Enterprise Application Architecture and

  • How to get the Class name of an API method?

    Like most of us, it's difficult to know where every method within a Java class is. Also, many of the same methods are scattered throughout Java Classes. I know of two methods that retreive this... getClass().getName(). But, you must have an object to use these. Is there a way to find out what Class contains a method or Class variable thru an Applet or Java Application?? Obviously, I can look at API Docs; but this takes time.

  • How to get the .class file for the extended Controller .java file

    Hi,
    I did the below steps.
    1. Created New OAWorkspace
    2. Created New project
    3. Imported the page .xml file
    4. Added new .java file by extending the controller class
    5. Added code in the .java file.
    6. Ran the .xml file
    As I copied all the folders from Unix box, the page was opened.
    But My question was where can I see the .class file the extended controller. It's a .java file. How to compile and get the .class file for this .java file. If I get this .class file, I can go to the page and click the personlize page. and change the Controller name to the new path by ftp ing the new class to the cust.oracle.apps.pos.changeorder.webiui.
    Please let me know how to create the .class file.
    Thanks,
    HP

    All are Java files are stored in JDEV_INSTALL_DIR:\jdevhome\jdev\myprojects\
    In your case the path java would be
    JDEV_INSTALL_DIR:\jdevhome\jdev\ myprojects \cust\oracle\apps\pos\changeorder\webui\
    AND
    Once you compile the java file in Jdeveloper, Class files get generated @ below path
    In your case the path of class would be
    JDEV_INSTALL_DIR:\jdevhome\jdev\ myclasses \cust\oracle\apps\pos\changeorder\webui\
