Interface Interceptor

All Known Implementing Classes:

ExceptionHandlerInterceptor, FlashInterceptor

public interface Interceptor

Whenever an interceptor accepts a controller method, its intercept method is invoked to intercept the process of request parsing in order to allow the software to do some specific tasks.
Common usage for interceptors for end-users (end-programmers) are security constraint checks, database session (open session in view) opening and much more.
