How is it possible to find all of the methods of a variable?
Local cStr := "Hello World!"
cStr:ClassName() ==>> "CHARACTER"
__objGetMethodList( cStr ) ==>> crashes and burns
How can I get a list of all of the available methods of cStr, like converting it to a number via a method of the variable?
Thanks,

Byron,
Please run FWH\samples\classtree.prg
With that PRG you can review all the classes that are linked in your app.
Basic types are simulated, they are not real classes. You can't see them in the above example.
/*
* Get the class name of an object
*/
const char * hb_objGetClsName( PHB_ITEM pObject )
{
HB_TRACE( HB_TR_DEBUG, ( "hb_objGetClsName(%p)", pObject ) );
if( HB_IS_ARRAY( pObject ) )
{
if( pObject->item.asArray.value->uiClass != 0 )
return s_pClasses[ pObject->item.asArray.value->uiClass ]->szName;
else
return "ARRAY";
}
/* built in types */
else if( HB_IS_NIL( pObject ) )
return "NIL";
else if( HB_IS_STRING( pObject ) )
return "CHARACTER";
else if( HB_IS_NUMERIC( pObject ) )
return "NUMERIC";
else if( HB_IS_DATE( pObject ) )
return "DATE";
else if( HB_IS_TIMESTAMP( pObject ) )
return "TIMESTAMP";
else if( HB_IS_LOGICAL( pObject ) )
return "LOGICAL";
else if( HB_IS_BLOCK( pObject ) )
return "BLOCK";
else if( HB_IS_HASH( pObject ) )
return "HASH";
else if( HB_IS_POINTER( pObject ) )
return "POINTER";
else if( HB_IS_SYMBOL( pObject ) )
return "SYMBOL";
else
return "UNKNOWN";
}Functions like __objGetMethodList do not work with Scalar values.
You can try this:
uVar := "Hello" // Any data type
xbrowser uVar:ClassSel()
You can see all symbols understood by this Scalar Class.
Some of them would be methods you may be interested in.
Actually, to the best of my knowledge, AsString() is a method commonly available in all Scalar classes and except for Arrays and Hashes, there are no other useful methods.
Even for array or hash, I do not think using the methods may be more efficient than using native functions.
