00047     if(_input == null) {
00048         _input = new JComboBox(_values);
00049     }
00050     return _input;

00054 {
00055     return null;
00056 }

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

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

Reimplemented from CorbaObjectChoice. 

00059 {
00060     String resName = null;
00061     try {
00062         //result = HxCorba."name"Helper.extract(resAny);
00063 
00064         Class helper = Class.forName("HxCorba."+_name+"Helper");
00065         Class[] argTypes = { Any.class };
00066         Method methExt = helper.getMethod("extract", argTypes);
00067         java.lang.Object[] args = { resAny };
00068         java.lang.Object obj = methExt.invoke(null, args);
00069 
00070         resName = toString(obj);
00071 
00072     }catch(Exception e) {
00073         ErrorStreamArea.println(e+": Cannot find helper class for "+_name);
00074     }
00075 
00076     return resName;
00077 }

void EnumChoice::setArgument (  Any    argsAny )  [inline, virtual]
 

Request management: add argument to Any.

Reimplemented from CorbaObjectChoice. 

00080 {
00081     java.lang.Object obj = asObject();
00082 
00083     try {
00084         //HxCorba."name"Helper.insert(argsAny, this);
00085

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

Converts that object to string.

Useful method to implement getResult.

Reimplemented from CorbaObjectChoice. 

00097 {

00100 
00101         Class enumC = Class.forName("HxCorba."+_name);
00102         Class[] argTypes = { };
00103         Method meth = enumC.getMethod("value", argTypes);
00104         java.lang.Object[] args = { };
00105         Integer v = (Integer)meth.invoke(obj, args);
00106         return _values[v.intValue()];
00107     }catch(Exception e) {
00108         ErrorStreamArea.println(e+": Cannot find HxCorba."+_name+".class");
00109     }
00110 
00111     return "unknown";
00112 }

java.lang.Object EnumChoice::asObject (  String    inText )  [inline, virtual]
 

Returns the object introduced as that text.

Useful method to implement setArgument.

Reimplemented from CorbaObjectChoice. 

00116 {
00117     return null; // never gets called
00118 }

java.lang.Object EnumChoice::asObject (    )  [inline]
 

Returns the object selected in that choice.

Useful method to implement setArgument.

Reimplemented from CorbaObjectChoice. 

00121 {
00122     int index = _input.getSelectedIndex();
00123     java.lang.Object result = null;
00124 
00125     try {
00126         //result = HxCorba."name".from_int(index);
00127 
00128         Class enumC = Class.forName("HxCorba."+_name);
00129         Class[] argTypes = { int.class };
00130         Method meth = enumC.getMethod("from_int", argTypes);
00131         java.lang.Object[] args = { new Integer(index) };
00132         result = meth.invoke(null, args);
00133     }catch(Exception e) {
00134         ErrorStreamArea.println(e.toString());
00135     }
