org.emftext.language.java.resolver.decider.ScopedTreeWalker

public class ScopedTreeWalker
extends Object

This class can be used to traverse a model tree after parsing for reference resolving. It follows scoping rules common to textual languages.

It starts at the point of the reference, walking up the tree but visiting, for each step up, the children of the new parent. On each visited element it applies a set of deciders with which it is initialized.
