org.codehaus.groovy.ast.ClassCodeVisitorSupport
org.codehaus.groovy.ast.ClassCodeExpressionTransformer
org.codehaus.groovy.control.ResolveVisitor

All Implemented Interfaces:
  `ExpressionTransformer`, `GroovyClassVisitor`, `GroovyCodeVisitor`, `ErrorCollecting`

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).
