Class ReaderInterceptorExecutor

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

All Implemented Interfaces:

InterceptorContext, ReaderInterceptorContext

public final class ReaderInterceptorExecutor
extends Object
implements ReaderInterceptorContext

Represents reader interceptor chain executor for both client and server side. It constructs wrapped interceptor chain and invokes it. At the end of the chain a message body reader execution interceptor is inserted, which finally reads an entity from the output stream provided by the chain.

Constructor Detail

ReaderInterceptorExecutor

public ReaderInterceptorExecutor(Class<?> rawType,
                                 Type type,
                                 Annotation[] annotations,
                                 MediaType mediaType,
                                 MultivaluedMap<String,String> headers,
                                 PropertiesDelegate propertiesDelegate,
                                 InputStream inputStream,
                                 MessageBodyWorkers workers,
                                 boolean intercept)

Constructs a new executor to read given type from provided entityStream. List of interceptors to be used is taken from given workers instance unless "jersey.runtime.reader.interceptors" property is set in propertiesDelegate. If such a property is present, the executor tries to cast it to List<ReaderInterceptor> and the list is then used to build the interceptor chain.

Parameters:

rawType - raw Java entity type.

type - generic Java entity type.

annotations - array of 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 - media type of the HTTP entity.

headers - mutable message headers.

propertiesDelegate - request-scoped properties delegate.

inputStream - entity input stream.

workers - Message body workers.

intercept - if set to true, user interceptors will be executed. Otherwise only exception wrapping interceptor will be executed on the client side.
