Class ASTTransformationVisitor
- All Implemented Interfaces:
- GroovyClassVisitor,- GroovyCodeVisitor,- ErrorCollecting
public final class ASTTransformationVisitor extends ClassCodeVisitorSupport
 ASTTransformationCollectorCodeVisitor will add a list
 of annotations that this visitor should be concerned about.  All other
 annotations are ignored, whether or not they are GroovyASTTransformation
 annotated or not.
 
A Two-pass method is used. First all candidate annotations are added to a list then the transformations are called on those collected annotations. This is done to avoid concurrent modification exceptions during the AST tree walk and allows the transformations to alter any portion of the AST tree. Hence annotations that are added in this phase will not be processed as transformations. They will only be handled in later phases (and then only if the type was in the AST prior to any AST transformations being run against it).
