Package gnu.expr

Class ResolveNames

java.lang.Object

gnu.expr.ExpVisitor<Expression,Void>

gnu.expr.ExpExpVisitor<Void>

gnu.expr.ResolveNames

All Implemented Interfaces:

SourceLocator, SourceLocator, Locator

Direct Known Subclasses:

XQResolveNames

public class ResolveNames
extends ExpExpVisitor<Void>

This resolves references to lexical Declarations. So far it is only used for XQuery, which overrides it. Lisp-family languages get similar functionality through the 2-phase scan/rewrite framework.
