Hi,
How I can distinguish nsCID from nsCIDPtr with xptinfo?
In C++, the difference is clear like below. But, I could not tell one
from another, when I deal with these methods with xptinfo.
// nsCID foo(); in IDL
NS_IMETHOD Foo(nsCID *_retval);
// nsCIDPtr foo2(); in IDL
NS_IMETHOD Foo2(nsCID * *_retval);
I tried nsXPTType::IsPointer(), expecting only the later returns
true. But, nsCID parameter also returned true. It seems to me
that they looked identical to nsIIDPtr type in terms of
XPTTypeDescriptorPrefix.
I looked into xpconnect and Python XPCOM, but could not figure
out how they treat nsCID type.
What I am trying to do is adding support for nsCID type to the
Ruby language binding, so that I can implement nsIClassInfo with
Ruby. Currently, I can not implement following attribute, because
nsCID* is mistaken as nsCID**.
readonly attribute nsCID classID;

Kenichi Komiya.
