ASTTransformation, org.objectweb.asm.Opcodes 
@GroovyASTTransformation(phase = CompilePhase.CANONICALIZATION)
public class CategoryASTTransformation
extends Object
implements ASTTransformation, org.objectweb.asm.Opcodes

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