Interface Interceptor

All Known Implementing Classes:

GlobalJavaInvokeInterceptor, JavaInvokeInterceptor, NoopInterceptor, PassThroughInterceptor

public interface Interceptor

The Interceptor is the component through which invocations pass through. In most cases the invocations pass through a series of Interceptor objects before the target object is invoked.

Interceptors should not store any data relevent to a particular invocation and potentially should not store any data relevent to a particular target object (It depends on the policy via which Interceptors are created via the ProxyManager).
