Interface WSIFInterceptor

public interface WSIFInterceptor

An interceptor gets the opportunity to pre- or post-process a service request or response, respectively, that's travelling through the WSIF. The interceptor also gets the opportunity to inform WSIF that the service is to be denied; i.e., that the service request (or response) should not be processed further.
