Class CategoryASTTransformation

java.lang.Object
org.codehaus.groovy.transform.CategoryASTTransformation
All Implemented Interfaces:
ASTTransformation

public class CategoryASTTransformation
extends java.lang.Object
implements ASTTransformation
Handles generation of code for the @Category annotation.

Transformation logic is as follows:

  • all non-static methods converted to static ones with an additional 'self' parameter
  • references to 'this' changed to the additional 'self' parameter

      public void visit​(ASTNode[] nodes, SourceUnit sourceUnit)
      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.
      sourceUnit - 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.
