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
.
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.

void aroundWriteTo(WriterInterceptorContext context) throws IOException, WebApplicationException
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.io.OutputStream)
method.
The parameters of the wrapped method called are available from context
.
Implementations of this method SHOULD explicitly call
WriterInterceptorContext.proceed()
to invoke the next interceptor in the chain,
and ultimately the wrapped MessageBodyWriter.writeTo
method.
context
- invocation context.
IOException
- if an IO error arises or is thrown by the wrapped
MessageBodyWriter.writeTo
method.
