Method Details

getSourceUnit

protected SourceUnit getSourceUnit()

Specified by:

getSourceUnit in class ClassCodeVisitorSupport

visit

public void visit(ASTNode[] nodes,
 SourceUnit source)

Description copied from interface: ASTTransformation

The method is invoked when an AST Transformation is active. For local transformations, it is invoked once each time the local annotation is encountered. For global transformations, it is invoked once for every source unit, which is typically a source file.

Specified by:

visit in interface ASTTransformation

Parameters:

nodes - The ASTnodes when the call was triggered. Element 0 is the AnnotationNode that triggered this annotation to be activated. Element 1 is the AnnotatedNode decorated, such as a MethodNode or ClassNode. For global transformations it is usually safe to ignore this parameter.

source - The source unit being compiled. The source unit may contain several classes. For global transformations, information about the AST can be retrieved from this object.

visitMethod

public void visitMethod(MethodNode node)

Description copied from interface: GroovyClassVisitor

Visit a MethodNode.

Specified by:

visitMethod in interface GroovyClassVisitor

Overrides:

visitMethod in class ClassCodeVisitorSupport

transform

public Expression transform(Expression expr)

Description copied from class: ClassCodeExpressionTransformer

NOTE: This method does not visit Expressions within Closures, for performance and historical reasons. If you want those Expressions to be visited, you can do this:

 
 public class YourTransformer extends ClassCodeExpressionTransformer {
   ...

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

       return expr;
     }
     // ...
   }
 }
 

Specified by:

transform in interface ExpressionTransformer

Overrides:

transform in class ClassCodeExpressionTransformer
