Interface ReaderInterceptor
public interface ReaderInterceptor
Interface for message body reader interceptors that wrap around calls
to MessageBodyReader.readFrom(java.lang.Class, java.lang.reflect.Type, java.lang.annotation.Annotation[], javax.ws.rs.core.MediaType, javax.ws.rs.core.MultivaluedMap, java.io.InputStream)
.
Message body interceptors implementing this interface must be annotated with
@Provider
to be discovered by the JAX-RS
runtime. Message body interceptor instances may also be discovered and
bound dynamically
to particular resource methods.

- Interceptor method wrapping calls to
MessageBodyReader.readFrom(java.lang.Class, java.lang.reflect.Type, java.lang.annotation.Annotation[], javax.ws.rs.core.MediaType, javax.ws.rs.core.MultivaluedMap, java.io.InputStream)
. The parameters
of the wrapped method called are available from context
.
Implementations of this method SHOULD explicitly call
ReaderInterceptorContext.proceed()
to invoke
the next interceptor in the chain, and ultimately the wrapped method.
- Parameters:
context
- invocation context.
- Returns:
- result of next interceptor invoked or the wrapped method if
last interceptor in chain.
- Throws:
java.io.IOException
- if an IO error arises.
WebApplicationException
- thrown by wrapped method.
