JVMAspectInterface
public interface JVMAspectInterface (Code)
Interface JVMAspectInterface represents the aspect-interface to the jvmai-system. It's needed for initialization of the jvmai-system, management of joinpoint-watches and for enable or disable event-notification.
An instance of this interface can be obtained by calling the method getAspectInterface() of a jvmai-provider (class Provider).

The prefixes are used by the jvmai system to determine the set of classes beeing relevant to the system at all. Depeding on the value of openWorldAssumption, prefixes are interpreted as followed:
openWorldAssumption == true
The jvmai-system is instructed to treat ALL classes as relevant, EXCEPT the ones contained in a packages starting with one of the supplied prefixes in packagePrefixes
openWorldAssumption == false
The jvmai-system is instructed to treat as relevant ONLY the classes contained in a packages starting with one of the supplied prefixes in packagePrefixes

  openWorldAssumption - Specifies how the prefixesare interpreted.
exception:
  StartupException - Use StartupException.getMessage()to get a detailed description

exception:
  NotInitializedException - Aspect-interface has not been initialized yet. Call setup first.
exception:
  NullPointerException - thread is null.

teardown
public void teardown()(Code)
Teardown the AOP support. As a result, no events will be sent to the JoinPointHook.
