Interface InterceptorInfo

All Superinterfaces:

BeanInfo

public interface InterceptorInfo
extends BeanInfo

Interceptors are managed beans annotated @Interceptor. An interceptor declares a set of interceptor binding annotations, used to associate the interceptor with target beans. It also declares at most one interceptor method for each interception type. Interception types are:

• @AroundInvoke: intercept business method invocations,
• @AroundConstruct: intercept constructor invocations,
• @PostConstruct: called after the container creates the target instance and completes dependency injection,
• @PreDestroy: called before the container destroys the target instance.

Finally, an interceptor also needs to declare a @Priority to become enabled.

Note that this description applies to CDI Lite. There are more ways to declare an interceptor, but those are only present in CDI Full.

4.0
