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.
