Description copied from interface: CodeTransformer

Apply recursively from the leaf node in the given TreePath.

annotations

public com.google.common.collect.ImmutableClassToInstanceMap<Annotation> annotations()

Description copied from interface: CodeTransformer

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:

@MyCustomAnnotation("value")
public class AnnotatedRefasterRule {
   @BeforeTemplate void before(String x) {...}
   @AfterTemplate void after(String x) {...}
}

You could retrieve the value of @MyCustomAnnotation from this map.
