Try derivedMembers instead.
That doesn't work, unfortunately, probably because of the types
I'm using(just returns object.
What I can do is this:
enum isElementOfObject(alias T) = (staticIndexOf!(T,
__traits(allMembers, Object)) < 0) ? true : false;
enum isElementOfIDispatch(alias T) = (staticIndexOf!(T,
__traits(allMembers, IDispatch)) < 0) ? true : false;
enum membersList = Filter!(isElementOfIDispatch,
Filter!(isElementOfObject, __traits(derivedMembers, T)));
It would be nice if instead of having to make a large list of
isElementOf____, I could pass the types to the predicate:
enum isElementOf(alias S, alias T) = (staticIndexOf!(T,
__traits(allMembers, S)) < 0) ? true : false;
enum membersList = Filter!(isElementOf!Object,
__traits(derivedMembers, T)));
and ultimately give a list of objects:
enum membersList = Filter!(isElementOf!(Object, IDispatch),
__traits(derivedMembers, T)));
Would be pretty cool if D could do that, but I doubt it can ;/
(not logically impossible, sort of like currying or something)
