problem with ITypeBinding.getQualifiedName() [message #258905]

I have a method declared like this:

public Set<Bar> getBars()

If I get the resolved binding for this method and
get the return type, by calling

IMethodBinding.getReturnType()

I get what appears to be the appropriate ITypeBinding back.
But a call to

ITypeBinding.getTypeDeclaration().getQualifiedName()

returns a String that looks like this:

"java.util.Set"

Unless I am confused by generics (which is often the case),
I am reading the JavaDoc for getQualifiedName() to mean that the
returned String should be something like this:

"java.util.Set<com.foo.Bar>"

The odd thing is that if I tweak the method declaration to be this:

public Set<Bar>[] getBars()

i.e. change the return type to be an array, getQualifiedName() then
returns:

"java.util.Set<com.foo.Bar>[]"

Am I missing something? Or is getQualifiedName() returning the incorrect
string here?

Thanks.

Never mind. :-)

Not five minutes after I pressed "Send" I noticed
my call to getTypeDeclaration():

ITypeBinding.getTypeDeclaration().getQualifiedName()

instead of just querying the type binding directly:

ITypeBinding.getQualifiedName()

I think I got lost in all the meta-ness....
