String StructChoice::getResult (  Any    resAny )  [inline, virtual]
 

Request management: extract result from Any (and convert it to String).

Reimplemented from CorbaObjectChoice. 

00074 {
00075     String resName = null;
00076 
00077     try {

String StructChoice::toString (  java.lang.Object    obj )  [inline]

Useful method to implement getResult.

00114 {
00115     String resName = _input.getSelectedItem().toString();
00116     if(resName.length() == 0) resName = _name+"*";

00124         for(int i=0; i<_fields.length; i++) {
00125             java.lang.Object fieldObj = c.getField(_fNames[i]).get(obj);
00126             String fVal = _fields[i].toString(fieldObj);
00127             result = result+_fNames[i]+": "+fVal+", ";

Useful method to implement setArgument.

Reimplemented from CorbaObjectChoice.

Reimplemented in PointChoice, and SizesChoice. 

00139 {
00140     java.lang.Object obj = StubRepository.instance().getStub(_id, name);
00141     if(obj == null)
