acces to the columns and values

[Former Member]

Hi All,

all what I need ist to know how to iterate a java.util.List which actually contains a table.

Clearly how can I acces to the columns and values ?

I get at editing this list object by NWDS many datas but not my columns and its

values. I have to itreate the list object line by line according to table structure

in order to update some lines or remove them.

Where are the columns and the table content ?

This is an extract of my list object inside NWDS

"elementData=Object[1857](id=358)"

elementCount= 1689

[0]= Charactconfig (id=360)

allAttributesChanged= false

allRolesChanged= false

associatedModel= BasicRFCModel (id=471)

attributesChangedModeInverse= false

baseTypeData= JcoBaseTypeData (id=482)

baseTypeDescriptor= JcoBaseTypeDescriptor (id=486)

changedAttributes= null

changedRoles= null

connectionType= 1

descriptor= AiiModelClass$Descriptor (id=490)

elementIdxForFrontendName= HashMap (id=492)

generationInfo= GenerationInfo (id=496)

keySet= null

modCount= 0

modelInstanceId= null

rolesChangedModeInverse= false

scope= WDModelScopeType (id=498)

1]= Charactconfig (id=360)

2]= Charactconfig (id=360)

......

.....

Hi,

Following is the code to iterate a list

	  List list =  //your list
	  
	  Iterator itr = list.iterator();
	  
	  while (itr.hasNext())
	  {
		  Object obj = itr.next(); // type cast this to your respective type.
		  
	  }

Ayyapparaj the requirement is to not show each information which are not

important for some plants. All the data which will be shown is in this list.

For some plants must some information be invisible. This ist the goal.

In order to do that I have to remove 10 lines. This list is provided by RFC Function Modul.

Actually it is a table in the backend.

Hi ,

I have the following information. What exactly is the type ?

public java.util.List get__Config_Tab() {

return (java.util.List)getRelatedModelObjects("__Config_Tab");

}

List list = xyzConfig.get__Config_Tab() ;

Debugger:

"list"= __Is_Charactconfig$__Is_Charactconfig_List (id=309)

associatedModel= BasicRFCModel (id=317)

baseList= JcoBaseList (id=328)

connectionType= 1

defaultScope= null

event= CMIObservableListEvent (id=333)

listeners= null

modelInstanceId= null

properties= XsdlElementProperties (id=336)

scope= WDModelScopeType (id=339)

Hi,

Most of the values of your list seem to be objects of different classes

Ex:baseList= JcoBaseList (id=328)

baseList contains an instance of JcoBaseList.

Could you explain why you need to extracting this data???

Hello,

there is a type mismatch message permanently by typecasting, what is wrong?

Hi,

Before type casting use the instanceOf to check and then do the type casting

Ex:

Object obj = itr.next(); // type cast this to your respective type.
		  if( obj instanceof String)
		  {
			  String str = (String)obj;
		  }
