Attach the boolean property to the row object. If it is true, then the row object was selected. You can also attach it to a Map<RowObjectId, Boolean> and then delete rows by RowObjectId which are true. You may find this article useful, it contains code examples: [http://balusc.blogspot.com/2006/06/using-datatables.html#SelectMultipleRows].

Set and get values with vector

I have a class that that querys a db and sets a value of the result to a vector array. Is it possible to set and retrieve that vector array using the set and get methods?
ex:
my class:
sql = "Select ...";
Vector fName = new Vector();
rs = sqlStatement.executeQuery(sql);
if (rs != null) {
while (rs.next()) {
fName.add(rs.getString("fName") + "");
rs.close();
setFName(fName);
how would I set up the set and get methods???
thanks

I am unsure of what you are asking:
A Vector has set and get methods for it, you use indexes of the array to say what element you want to work with.
If you are asking how do you know what elements of the Vector contain which data columns, you have to remember how you put them in.
If you are asking if you can use set to load the Vector: then NO, you have to have elemenets already there to change, use the add method.
If you are asking how to access the elements of the Vector you use an Enumeration:
for(java.util.Enumeration e = v.elements(); e.hasMoreElements();){
s = (java.lang.String) e.nextElement();
vl.add(s.substring(0, 12));
If you are asking something else: please elaborate what you want--my brain may not be very functional this morning.

Doubts in CMP Setter and Getter Methods

Hi. Just like to clarify something on CMP.
May I know if there are 6 fields in my database table and I declared only getter and setter methods for 5 of the fields only, will this post any problem in WL8.1?
Also, suppose I have 6 fields in my database table and I declared 6 setter and getter methods. Throughout my program I only trigger 2 setter methods, will the other 4 setter methods that I didnt trigger set a null or 0 to the fields (since I didn't set any value to them)?
Thanks and appreciate.

Unset fields will usually be set to their default value, i.e. null for Objects. You don't have to define / execute setters for columns in the database unless they are non-nullable.

Set and get parameter id

Hi,
I need to store one variable value and I need to retrieve the same variable value in same program. For this I have written set and get parameter ids in the same program. It is working fine but if I log off the system and if I logon the system it is not working I mean before log off the variable is showing some value if I log on again that variable is showing empty. But I want to capture the field values after log off and log on also. Is there any other option can I use table?
Please help me I will give points.
Thanks.

Hi
SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement. Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens
SAP global memory retains field value through out session.
set parameter id 'MAT' field v_matnr.
get parameter id 'MAT' field v_matnr.
They are stored in table TPARA.
ABAP memory is a memory area that all ABAP programs within the same internal session can access using the EXPORT and IMPORT statements. Data within this area remains intact during a whole sequence of program calls. To pass data
to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse.
ABAP memory is temporary and values are retained in same LUW.
export itab to memory id 'TEST'.
import itab from memory Id 'TEST'.
Here itab should be declared of same type and length.

Accessing Custom Controller from setter and Getter methods

Hi Gurus
How can we access the custom controller from setter and getter methods,is there any way to do that.
Thanks & Regards
Rajasekhar

Hi Steve.
Thanks very much for valuable information, the main controller class is getting tracked in mo_owner which is declared as CL_BSP_WD_VIEW_CONTROLLER, and I'm getting the reference through
mo_owner ?= owner. (since mo_owner = owner is not getting converted of type mo_owner ). After doing this on whatever the contexnode class (say zl_xxxx_xxx_cnxx) the corressponding context node values are getting turned as <#ERROR IN METADATA.
I mean when I'm checking the configuration in bsp_wd_cmpwb configuration tab -> Available Fields->Enlarge the contex node->BTSTATUS (say for Example) there the values are showing as <#ERROR IN METADATA , After executing the above procedure
I cross checked several times before and after redefining the context node method IF_BSP_MODEL~INIT, before redefining this method UI is working fine, after redefintion UI is throwing below error .
Exception Details
CX_SY_REF_IS_INITIAL - Dereferencing of the NULL reference
Method: CL_BSP_MODEL=>IF_BSP_MODEL_BINDING~IS_ATTRIBUTE_VALID
Source Text Row: 13
Thanks & Regards

Regarding setter and getter methods

Hi,
Can anybody tell me the use of setter and getter methods in webdynpro .
It is generated when we set the calculate property of value attribute to true .
Thanks a lot .

Hi Jain
setter and getter functions will be created when you set the calculated propertyto true
Consider the following scenario where in you can get some basic idea
1) First insert a Child "Image" UI Element
2) Create a Context in a view in which you are using Image UI Element
3) Value Node
Name : Image
Cardidality : 1..1
4) create 2 Value Attributes
4)a ImageAlt (Calculate property - true) //this will create getter and setter methods
4)b ImageSrc (Calculate property - true) //this will create getter and setter methods
5)Bind the properties of Image
alt - Image.ImageAlt
source - Image.ImageSrc
6) in getImageSrc()
retrun "XX.gif"
7) in getImageAlt()
return "Image Not Available"
you can even achieve getter and setter methods by doing the following procedure
goto implementation tab-> rightclick -> source -> generate Getter and Setter methods...

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

Hi,
Use NVL or COALESCE:
NVL (col_a, col_b)
Returns col_a if col_a is not NULL; otherwise, it returns col_b.
Col_a and col_b must have similar (if not identical) datatypes; for example, if col_a is a DATE, then col_b can be another DATE or it can be a TIMESTAMP, but it can't be a VARCHAR2.
For more about NVL and COALESCE, see the SQL Language manual: http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions119.htm#sthref1310
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

Script label: Set and get it?

Hi
How can I set and get the script label of a frame in my plugin?
Thanks for the help.
Best regards

Hi, the IScript-Interface has a GetTag() and SetTag() method. While GetTag() is fine, you'll get Asserts when using SetTag() - thus I changed that to processing kSetScriptingTagCmdBoss. Example (script-label on a splineitem, stripped of nil-pointer-checks): InterfacePtr<IScript> script(itemRef, UseDefaultIID()); PMString label = script->GetTag(); ScriptList scriptList.push_back(script); InterfacePtr<IScriptManager>scriptMgr(Utils<IScriptUtils>()->QueryScriptManager(kScript TagMgrBoss)); InterfacePtr<ICommand> cmd( CmdUtils::CreateCommand(kSetScriptingTagCmdBoss)); InterfacePtr<IScriptTagCmdData> scriptTagData(cmd, UseDefaultIID()); scriptTagData->SetScriptList(scriptList, scriptMgr->GetRequestContext(), label); cmd->SetItemList(UIDList(itemRef)); ErrorCode err = CmdUtils::ProcessCommand(cmd); Regards, Bernt

Auto Javadoc for Setter and getter methods

Hi
Is there a way to include javadoc while creating a Setter and getter itself?
Thanks
Tanjith

but why addign javadoc to a getter/setter anywhy?Oracle [url http://download.oracle.com/docs/cd/E16162_01/apirefs.1112/e17483/oracle/jbo/common/AccTravDefImpl.html#getAccTravQualifiers()]does, so it must be OK :)
But as Timo says, there's no automatic way that I know of. I suppose you could do something like that by making your own code template.

You need to install Java SE 6 to run those programs. There has been quite a bit of discussion here about that. Something at one of these links should get you going...
