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).

 public class YourTransformer extends ClassCodeExpressionTransformer {
   ...

   @Override
   public Expression transform(final Expression expr) {
     if (expr instanceof ClosureExpression) {
       expr.visit(this);

       return expr;
     }
     // ...
   }
 }
