Class ReaderInterceptorExecutor

java.lang.Object
  org.glassfish.jersey.message.internal.ReaderInterceptorExecutor

All Implemented Interfaces:

InterceptorContext, ReaderInterceptorContext

public class ReaderInterceptorExecutor
extends java.lang.Object
implements ReaderInterceptorContext

Entry point of the reader interceptor chain. It contstructs the chain of wrapped interceptor and invokes it. At the end of the chain MessageBodyWriter MBW is invoked which writes the entity to the output stream. The ExceptionWrapperInterceptor is always invoked on the client as a first interceptor.

Constructor Detail

ReaderInterceptorExecutor

public ReaderInterceptorExecutor(GenericType genericType,
                                 java.lang.annotation.Annotation[] annotations,
                                 MediaType mediaType,
                                 MultivaluedMap<java.lang.String,java.lang.String> headers,
                                 java.util.Map<java.lang.String,java.lang.Object> properties,
                                 java.io.InputStream inputStream,
                                 MessageBodyWorkers workers,
                                 boolean intercept)

Reads a type from the entityStream using interceptors.

Parameters:

genericType - the generic type that is to be read from the input stream.

annotations - an array of the annotations on the declaration of the artifact that will be initialized with the produced instance. E.g. if the message body is to be converted into a method parameter, this will be the annotations on that parameter returned by Method.getParameterAnnotations.

mediaType - the media type of the HTTP entity.

httpHeaders - the mutable HTTP headers associated with HTTP entity.

properties - the mutable map of request-scoped properties.

entityStream - the InputStream of the HTTP entity. The stream is not closed after reading the entity.

workers - Message body workers.

intercept - true if the user interceptors should be executed. Otherwise only exception wrapping interceptor will be executed in the client.

Throws:

WebApplicationException - Thrown when message body reader fails.

java.io.IOException - Thrown when reading from the entityStream fails.
