Method Summary

T	aroundReadFrom(ReaderInterceptorContext<T> context) 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).

Method Detail

aroundReadFrom

T aroundReadFrom(ReaderInterceptorContext<T> context)
                 throws IOException,
                        WebApplicationException

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:

IOException - if an IO error arises.

WebApplicationException - thrown by wrapped method.
