All Implemented Interfaces:

ExpressionTransformer, GroovyClassVisitor, GroovyCodeVisitor

Direct Known Subclasses:

JavaAwareResolveVisitor

public class ResolveVisitor
extends ClassCodeExpressionTransformer

Visitor to resolve Types and convert VariableExpression to ClassExpressions if needed. The ResolveVisitor will try to find the Class for a ClassExpression and prints an error if it fails to do so. Constructions like C[], foo as C, (C) foo will force creation of a ClassExpression for C

Note: the method to start the resolving is startResolving(ClassNode, SourceUnit).
