public class AspectMetadata
extends Object

Metadata for an AspectJ aspect class, with an additional Spring AOP pointcut for the per clause.

Uses AspectJ 5 AJType reflection API, so is only supported on Java 5. Enables us to work with different AspectJ instantiation models such as "singleton", "pertarget" and "perthis".
