Package javax.ws.rs.ext
Interface WriterInterceptor
public interface WriterInterceptor
Interface for message body writer interceptors that wrap around calls
to
MessageBodyWriter.writeTo(T, java.lang.Class<?>, java.lang.reflect.Type, java.lang.annotation.Annotation[], javax.ws.rs.core.MediaType, javax.ws.rs.core.MultivaluedMap<java.lang.String, java.lang.Object>, java.io.OutputStream)
.
Providers implementing WriterInterceptor
contract must be either programmatically
registered in a JAX-RS runtime or must be annotated with
@Provider
annotation to be automatically discovered
by the JAX-RS runtime during a provider scanning phase.
Message body interceptor instances may also be discovered and
bound dynamically
to particular resource methods.

aroundWriteTo
Interceptor method wrapping calls toMessageBodyWriter.writeTo(T, java.lang.Class<?>, java.lang.reflect.Type, java.lang.annotation.Annotation[], javax.ws.rs.core.MediaType, javax.ws.rs.core.MultivaluedMap<java.lang.String, java.lang.Object>, java.io.OutputStream)
method. The parameters of the wrapped method called are available fromcontext
. Implementations of this method SHOULD explicitly callWriterInterceptorContext.proceed()
to invoke the next interceptor in the chain, and ultimately the wrappedMessageBodyWriter.writeTo
method.- Parameters:
context
- invocation context.- Throws:
IOException
- if an IO error arises or is thrown by the wrappedMessageBodyWriter.writeTo
method.WebApplicationException
- thrown by the wrappedMessageBodyWriter.writeTo
method.
