This package provides a set of interfaces for interception mechanisms.

Interception is a basic mechanism to implement AOP. This is widely used in middlewares and modern application servers, including J2EE ones.

This package provides an {@link org.aopalliance.intercept.Interceptor} interface that will intercept different runtime joinpoints (e.g. method calls, field access, ...). Thus, interceptors are able to add some behavior around the joinpoints actual executions. Several interceptors can be applied on a given joinpoint since they are chained. The AO system implementor should provide means to install and order these chains of interceptors.
