Getting ITypeBinding from a fully qualified class name. Is it possible? [message #259445]

This question has been asked before but no one gave a universal solution.

ITypeBinding has several methods: isAssignmentCompatible, isCastCompatible
and isSubTypeCompatible that take an ITypeBinding as a parameter.

I need to use one of this method to check if a ITypeBindig is a collection
so I want to get an ITypeBinding from
"java.util.Collection" and then use isSubTypeCompatible. So I need the
ITypeBinding of java.util.Collection.

AST.resolveWellKnownType only works for well known types. Why there is not
an AST.resolveType?

Thank you in advance.

When you parse compilation unit(s), you can provide keys for additional
bindings you will be interested in. See ASTParser.createASTs. The only
problem with this approach is that you need to now in advance (at the time
you parsed the unit) which additional bindings you will need.
