org.glassfish.jersey.message.internal.InterceptorExecutor<javax.ws.rs.ext.WriterInterceptor>

org.glassfish.jersey.message.internal.WriterInterceptorExecutor

All Implemented Interfaces:

javax.ws.rs.ext.InterceptorContext, javax.ws.rs.ext.WriterInterceptorContext, InjectionManagerSupplier, PropertiesDelegate

public final class WriterInterceptorExecutor
extends InterceptorExecutor<javax.ws.rs.ext.WriterInterceptor>
implements javax.ws.rs.ext.WriterInterceptorContext, InjectionManagerSupplier

Represents writer 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 writer execution interceptor is inserted, which writes entity to the output stream provided by the chain.

Constructor Details

WriterInterceptorExecutor

public WriterInterceptorExecutor(Object entity,
 Class<?> rawType,
 Type type,
 Annotation[] annotations,
 javax.ws.rs.core.MediaType mediaType,
 javax.ws.rs.core.MultivaluedMap<String,Object> headers,
 PropertiesDelegate propertiesDelegate,
 OutputStream entityStream,
 MessageBodyWorkers workers,
 Iterable<javax.ws.rs.ext.WriterInterceptor> writerInterceptors,
 InjectionManager injectionManager)

Constructs a new executor to write given type to provided entityStream.

Parameters:

entity - entity object to be processed.

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 HTTP headers associated with HTTP entity.

propertiesDelegate - request-scoped properties delegate.

entityStream - InputStream from which an entity will be read. The stream is not closed after reading the entity.

workers - Message body workers.

writerInterceptors - Writer interceptors that are to be used to intercept writing of an entity.

injectionManager - injection manager.
