here's my problem. when walking down the AST, I'd like to find the declaring
node of certain bindings when those bindings aren't declared in the current
compilation unit. for instance, when I reach a Type, I would like to look up the
ITypeBinding and somehow obtain the TypeDeclaration for that type, even if it
isn't declared in the same file. or when I reach a MethodInvocation, I need to
look up the MethodDeclaration for that invocation. right now, this only seems
possible if the declaration nodes are from the same source using
findDeclaratingNode.

when ASTParser parses Java source, does it create a CompilationUnit for every
source file required for compilation? if so, could those be made available
somehow through the AST, such as a AST.getCompilationUnits() method? if they're
not current constructed, could a new createAST method be added to ASTParser that
would do so?

here's an example for two separate Java source files, A.java and B.java.

class A {
  void m(B b) {
    b.n()
  }
}

class B {
  void n() {}
}

I would like to be able to create a CompilationUnit for A.java, and when I reach
the invocation b.n(), I would like to retrieve the MethodDeclaration node for n
that is in the CompilationUnit of B.java.


is there any easy way to do this currently? I can't find one.
