finding the implementing interfaces of an IType [message #99132]

Hi,

Suppose I have an instance of IType. I want to get the list of immediate
interfaces it implements. I found there are two options -
1. use IType#getSuperInterfaceNames() and then IType#resolveType()
2. use IType#newSupertypeHierarchy() and then
ITypeHierarchy#getSuperInterfaces

I found that these methods are too slow for me, because I invoke them on
almost all files in a java project.

Can anybody provide an insight on how to do perform this operation most
efficiently?

Thanks,
Genady

You could build the type hierarchy once on the Java project using
IJavaProject.newTypeHierarchy(IRegion, IProgressMonitor) passing in a region
that contains the whole project. This will resolve the super types of all
types in the region only once.
