RE: [cdt-dev] How to Get The Scope of a Node
|
A correction:
IBinding.getScope() returns the scope in which the binding is declared
(not the scope that it represents).
For references CPPVisitor.getContainingScope(name) will find the scope
in which the reference is made, whereas name.resolveBinding().getScope()
returns the scope in which the referenced entity is declared. There are
also subtle differences for declarations and definitions.
To find references for a variable you best use:
IASTTranslationUnit.getReferences(IBinding)
