Contains interfaces that extend Signature to provide additional information about each possible join point signature. This additional information can be accessed by casting a Signature object to the appropriate type, i.e.

  before(): call(* *(..)) {
      MethodSignature sig = (MethodSignature)thisJoinPoint.getSignature();
      ...
  }

This package also contains SourceLocation that provides information about the location in source code that corresponds to a particular join point.
