How to look into a method?

Hello all:
I am wondering if there is a way to look into a method simply by its name? As we all know, we can get the detail description of most of the classes in JAVA by browsing online documentation:
- API & Language Documentation
- Java 2 Platform API Specification .
On the page, there is a left frame listing class names in alphebetical order. By clicking on a particular class name, we can get the description of that class on right frame.
It's very convenient.
Therefore, I want to know if there is a way to get the description of methods in the same manner as classes. Is there a webpage which lists most of the methods in JAVA language and its descriptions? So that we can check the detail of a method without knowing which class it belongs to. I think it should be very useful. Because there are times we see a new method name and unfortunately we don't know which class it belongs to. Thus, it is a bit difficult to check the detail of that method because we don't know its class name.
That is why I am looking for a way to check the detail of a method in the same manner as a class.

Thanks to you all:
Yes, I find the index and it works. However, I am just not smart enough to find that search link. Mwstein, can you point to me where can I find that search link? Thanks again for your replies.

How to look into all fields (beginner question)

Hello,
I have a table which contains a series of columns like
'GRPREF00', 'GRPREF01', 'GRPREF02', ... 'GRPREF19'.
If I want to know whether the number 34 is in one of these columns, I use the following command:
Select * from <table_name> where 34 in ('GRPREF00', 'GRPREF01', 'GRPREF02', ... 'GRPREF19');
Obviously I cannot use the "..." and I am writing all the time the whole series of columns.
In order to shorten this command, I have already tried teh following command:
Select * from <table_name> where 34 in (*);
but this didn't work.
Does anybody know whether/how it is possible to define a range of columns to look in or whether/how it is possible to search through all the columns of a table?
Thanks
Dominique

Hello
That was really the gist of the original question. It was to find out if any columns contain 34 rather than any columns named 34. Just as a side note, your query would return 0 rows unless the column name was surrounded by double quotes when it was created:
CREATE TABLE dt_test_col (34 varchar2(10))
CREATE TABLE dt_test_col ("34" varchar2(10))
SELECT COUNT(1) counter
FROM user_tab_columns
WHERE column_name='34'
AND table_name= 'DT_TEST_COL' ;Another option, which is similar to one of the methods the OP tried is:
WITH test_data AS
(     SELECT
          CAST(NULL AS VARCHAR2(2)) AS col1,
          CAST(NULL AS VARCHAR2(2)) AS col2,
          CAST(NULL AS VARCHAR2(2)) AS col3,
          CAST(NULL AS VARCHAR2(2)) AS col4,
          CAST(NULL AS VARCHAR2(2)) AS col5,
          '34' AS col6,
          CAST(NULL AS VARCHAR2(2)) AS col7,
          CAST(NULL AS VARCHAR2(2)) AS col8,
          CAST(NULL AS VARCHAR2(2)) AS col9,
          CAST(NULL AS VARCHAR2(2)) AS col10
     FROM
          dual
SELECT
FROM
     test_data
WHERE
     '34' IN (col1,col2,col3,col4,col5,col6,col7,col8,col9,col10)
This does mean that you have to list all of the columns you want to check in the in statement, but the tradeoff is that you don't end up having to write dynamic sql.
The IN statement will likely be transformed by the optimizer into:
Predicate Information (identified by operation id):
   3 - filter("TEST_DATA"."COL1"='34' OR "TEST_DATA"."COL2"='34' OR
              "TEST_DATA"."COL3"='34' OR "TEST_DATA"."COL4"='34' OR "TEST_DATA"."COL5"='34' OR
              "TEST_DATA"."COL6"='34' OR "TEST_DATA"."COL7"='34' OR "TEST_DATA"."COL8"='34' OR
              "TEST_DATA"."COL9"='34' OR "TEST_DATA"."COL10"='34')Which saves you even more typing! :-)

We had a contaminated email and now we cannot send emails . our service provider thinks problem in 'mail' settings but did not want to get into that area. Can you advise how we look into this

we had a contaminated email and now we cannot send emails. Our service provider advises that 'Mail' settings may be compromised. but were not willing to get into resetting. How can this be fixed ?

Not exactly sure what you mean by contaminated, but there is currently no known e-mail that could impact the Apple Mail application as you have described.
Without knowing who your e-mail provider is and what type of account (IMAP or POP3) we can't advise you as to what those settings might be.
One way to fix it would be to delete the account from Apple Mail Preferences->Accounts and add it back.

How to call a java method so I can pass a file into the method

I want to pass a file into a java method method from the main method. Can anyone give me some help as to how I pass the file into the method - do I pass the file name ? are there any special points I need to put in the methods signature etc ?
FileReader file = new FileReader("Scores");
BufferedReader infile = new BufferedReader(file);
Where am I supposed to put the above text - in the main method or the one I want to pass the file into to?
Thanks

It's a matter of personal preference really. I would encapsulate all of the file-parsing logic in a separate class that implements an interface so that if in the future you want to start taking the integers from another source, e.g. a db, you wouldn't need to drastically alter your main application code. Probably something like this, (with an assumption that the numbers are delimited by a comma and a realisation that my file-handling routine sucks):
public class MyApp{
public static void main(String[] args){
IntegerGather g = new FileIntegerGatherer();
Integer[] result = g.getIntegers(args[0]);
public interface IntegerGatherer{
public Integer[] getIntegers(String location);
import java.io.*;
public class FileIntegerGatherer implements IntegerGatherer{
public Integer[] getIntegers(String location){
FileInputStream fs=null;
try{
File f = new File(location);
fs = new FileInputStream(f);
byte[] in = new byte[1024];
StringBuffer sb = new StringBuffer();
while((fs.read(in))!=-1){
sb.append(new String(in));
StringTokenizer st = new StringTokenizer(sb.toString(),",");
Integer[] result = new Integer[st.countTokens()];
int count = 0;
while(st.hasMoreTokens()){
result[count]=Integer.valueOf(st.nextToken());
count++;
catch(IOException e){
//something sensible here
finally{
if(fs!=null){
try{
fs.close();
catch(IOException f){
return result;
Once compiled you could invoke it as java MyApp c:\myInts.txt
Sorry if there are typos in there, I don't have an ide open ;->

My 12" powerbook logics card crashed. I have a 17". How do i retrieve my internet bookmarks from the 12" by putting it into Target mode on the 12" and looking into the hard drive on the 12"?

My 12" powerbook logics card crashed. I have a 17". How do I retrieve my internet bookmarks from the 12" by putting it into Target mode on the 12" and looking into the hard drive on the 12"? Where on the 12" hard drive do I go to search for them?

If the 12's logic board is trashed, I don't think you can get into FireWire Target Disk Mode. The computer has to start to get to FWTDM. Will it starte and run at all?
If it won;t start, you will have to go inside and extract the hard drive. Then get this gadget:
Newer Technology Universal Drive Adapter USB 3.0/2.0 - connects any 2.5", 3.5" or 5.25" drive
It allows you to connect a bare drive to another computer that has USB. It will act just like an external disk drive. Assuming the 12's drive is not damaged due to the LB failure, you can retrieve files quickly.

I am looking into Buying Retail a New Blackberry Q10. Doing this to avoid having to Give up my old Data Plan. Have read that when you activate a new Phone it forces you to pick a new Plan. Is this True? and How to I avoid this? 20 Year Verizon Client

I am looking into Buying Retail a New Blackberry Q10. Doing this to avoid having to Give up my old Data Plan. Have read that when you activate a new Phone it forces you to pick a new Plan. Is this True? and How to I avoid this? Any other advise in this matter would be greatly appreciated.

The only "unlimited" plan I can think of where this would not apply is the old Connect plan for multimedia/basic phones. That unlimited data, on devices such as the LG Voyager, EnvTouch, and other "multimedia" devices is not the same.
If you currently have an individual $29.99 unlimited data plan with a 3G Smartphone, then you can buy a BBQ10 retail and activate it with the same data plan and keep the unlimited.

How do u pass an object into a method

I want to create a method getData that takes an object of type Helper and returns an object of the same type.
how do u pass objects into a method and how do u get objects as returns im a bit confused

That will just allow you to pass a parameter. If you want to return a helper object
Helper paramHelper = new Helper();
Helper someHelper = callMethod(paramHelper);
public Helper callMethod(Helper hobj) {
    //<some code>
    Helper retHelper = new Helper();
    //<blah, blah>
    return retHelper;

Most of us in this forum are users who volunteer on technical issues, and not Adobe employees although they do drop in from time to time. As users we simply have no control over activation and that's why you are not getting responses.
If you havn't done so,you might try the Muse forums and see if you can get a staff member to look into it. Have your case numbers and phone transcripts handy.
Last option is to keep calling customer service until you get someone who will help or ask for a supervisor.
Hope this get resolved,

How to check a single method is overriden in how many subclasses in ABAP.

Hi Experts,
I have a global superclass which had benn inherited by many other global subclasses. Is there any way to find out quickly (may be in a table ) in how many subclasses a particular method of the superclass is overriden?

Hi Manuish,
You can use the class CL_OO_CLASS to achieve the above, below is a sample code.
DATA: lcl_oo_class TYPE REF TO cl_oo_class,
      lw_seoredef TYPE seoredef.
TRY.
    CREATE OBJECT lcl_oo_class
      EXPORTING
        clsname = 'Y_TEST_CHEN_CLASS_SUB1'.
CATCH cx_class_not_existent .
ENDTRY.
WRITE: 'Class', '                              ', 'Refclass', '                         ', 'Over written method', /.
LOOP AT lcl_oo_class->redefinitions INTO lw_seoredef.
WRITE: lw_seoredef-clsname,'         ',
         lw_seoredef-refclsname,'         ',
         lw_seoredef-mtdname,'         ', /.
ENDLOOP.
Alternatively you can look up the table "SEOREDEF" directly.

Hi All,
    I have inspection lot number (PRUEFLOS), batch number
   (CHARGE), plant (WERK) & material number
   (MATNR) , using these fields how to get the inspection
   method (PMETHODE) & Characteristic Value (ATWRT) ?
   I dont know the relation among them.
Could you please help?
Thanks in advance.

Hi Jose,
Thanks for your help, could you please look into my requirement.
For all inspection characteristics listed in the selected COA profile, I have to retrieve the Inspection Method for all listed inspection characteristics. And also I have to retrieve the characteristic value(uncertainty). Additionally, for inspection characteristics that are quantitative, being checked, the characteristic value(uncertainty) from that Inspection method will be retrieved from class 3050_UNCERTAINTY, class type 006, characteristic, P2150_UNCERTAINTY.
Please help me out.

How to implement classes and methods in badi's ?

how to implement classes and methods in badi's? and where i have to write the code based on the requirement?can anyone explain me briefly?

Hi
Every BADI by default Implements an INTERFACE which already contains some methods with parameters.
So you have to find the relavenet method based on the related paramters (by checking the fields in that paramters) you have to double click on the method and to write the code.
see the doc
DEFINING THE BADI
1) execute Tcode SE18.
2) Specify a definition Name : ZBADI_SPFLI
3) Press create
4) Choose the attribute tab. Specify short desc for badi.. and specify the type :
multiple use.
5) Choose the interface tab
6) Specify interface name: ZIF_EX_BADI_SPFLI and save.
7) Dbl clk on interface name to start class builder . specify a method name (name,
level, desc).
Method level desc
Linese;ection instance methos some desc
8) place the cursor on the method name desc its parameters to define the interface.
Parameter type refe field desc
I_carrid import spfli-carrid some
I_connid import spefi-connid some
9) save , check and activateadapter class proposed by system is
ZCL_IM_IM_LINESEL is genereated.
IMPLEMENTATION OF BADI DEFINITION
1) EXECUTE tcode se18.choose menuitem create from the implementation menubar.
2) Specify aname for implementation ZIM_LINESEL
3) Specify short desc.
4) Choose interface tab. System proposes a name fo the implementation class.
ZCL_IM_IMLINESEL which is already generarted.
5) Specify short desc for method
6) Dbl clk on method to insert code..(check the code in AAA).
7) Save , check and activate the code.

loop at it_spfli into wa_spfli.
write:/ wa_spfli-carrid,
wa_spfli-connid,
wa_spfli-cityfrom,
wa_spfli-deptime,
wa_spfli-arrtime.
hide: wa_spfli-carrid, wa_spfli-connid.
endloop.
at line-selection.
check not wa_spfli-carrid is initial.
create object exit_ref.
exit_ref1 = exit_ref.
call method exit_ref1->lineselection
EXPORTING
i_carrid = wa_spfli-carrid
i_connid = wa_spfli-connid.
clear wa_spfli.

How to scan soure of methods?

I want to scan source of methods.
For exapmle, Class Interface "CL_IM_FI_HEADER_1300_FS" has 4 methods.
IF_EX_FI_HEADER_SUB_1300~PUT_DATA_TO_SCREEN_PBO
IF_EX_FI_HEADER_SUB_1300~PUT_DATA_TO_SCREEN_PAI
IF_EX_FI_HEADER_SUB_1300~GET_DATA_FROM_SCREEN_PBO
IF_EX_FI_HEADER_SUB_1300~GET_DATA_FROM_SCREEN_PAI
How can I scan these?
Please help me.
I use
READ REPORT
, but it doesn't work.
Edited by: Jaime White 999 on Sep 22, 2011 10:55 AM

You need the methods used in the class or the code written in the method ?
If you need methods used in class
check my wiki link:[http://wiki.sdn.sap.com/wiki/display/ABAP/ListallMethods,Attributes,Eventsofa+Class]
For second case i just searched in my system and got SCAN_ABAP_OBJECTS_CLASSES, SCAN_ABAP_OBJECTS_SECTION and some more. Please have a look into it.
You can make use of function SEO_METHOD_GET_SOURCE as said in this contribution [download_abap_class|http://www.sapnet.ru/viewtopic.php?p=7706]
