RE: CORBA_any question

["Johan Antonsson" <johan antonsson com>]

Thanks Michael,

Seem like I've used an approach similar to yours. Can you tell me some
more about the nasty _value syntax for strings? 

What about fields of structs transported in any's? Do they also have a
funny syntax?

Regards

/Johan

	Well - there is the DynamicAny interface - cf.
ORBit2/src/orb/dynany/*
- however it sucks more than you can imagine ( as an interface :-). If
you want to do deeply complex stuff in a standard way though - that's
the code you want.

	OTOH - you don't want that; I tend to do this:

	CORBA_any stack_any;
	stack_any._type = TC_CORBA_double;
	stack_any._value = &stack_double;
	DoCorbaMethod(obj, &stack_any, ev);

	But that's just me - and you come slightly unstuck with strings
- which
have a slightly nasty _value syntax.

	We have some accessors in libbonobo - however, they're of the
31337
"don't allocate anything' variety - and suck badly for type safety; we
need to expand that code really to make Anys more usable.

	HTH,

		Michael.
