  • Method Details

    • apply

      void apply​(com.sun.source.util.TreePath path, com.sun.tools.javac.util.Context context, DescriptionListener listener)
      Apply recursively from the leaf node in the given TreePath.

    • annotations

      com.google.common.collect.ImmutableClassToInstanceMap<Annotation> annotations()
      Returns a map of annotation data logically applied to this code transformer.

      As an example, if a CodeTransformer expressed as a Refaster rule had an annotation applied to it: 

      
 {@literal @}MyCustomAnnotation("value")
 public class AnnotatedRefasterRule {
    {@literal @}BeforeTemplate void before(String x) {...}
    {@literal @}AfterTemplate void after(String x) {...}
 }
      You could retrieve the value of @MyCustomAnnotation from this map.
