# Class ResolveVisitor

java.lang.Object
org.codehaus.groovy.ast.CodeVisitorSupport
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)`.
