| <P> |
| When extending AspectJ's pointcut parsing and |
| matching with custom PointcutDesignatorHandlers, |
| it may be necessary to match based on context information |
| at a join point not exposed simply by java.lang.reflect |
| member information or argument values. The matching context |
| interface provides an extension point for the specification |
| of additional shadow and join point context that can be |
| taken into account during the matching process. |
