28.3. PostProcessInterceptors

The org.jboss.resteasy.spi.interception.PostProcessInterceptor runs after the JAX-RS method is invoked but before MessageBodyWriters are invoked. They can only be used on the server side, and exist to provide symmetry with PreProcessInterceptor. They are used to set response headers when there is a possibility that no MessageBodyWriter will be invoked. They do not wrap any object, and are invoked in order, like PreProcessInterceptors.
    public interface PostProcessInterceptor
    {
       void postProcess(ServerResponse response);
    }
