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

org.glassfish.jersey.message.internal.ReaderInterceptorExecutor

All Implemented Interfaces:

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

public final class ReaderInterceptorExecutor
extends InterceptorExecutor<javax.ws.rs.ext.ReaderInterceptor>
implements javax.ws.rs.ext.ReaderInterceptorContext, InjectionManagerSupplier

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 Details

ReaderInterceptorExecutor

ReaderInterceptorExecutor(Class<?> rawType,
 Type type,
 Annotation[] annotations,
 javax.ws.rs.core.MediaType mediaType,
 javax.ws.rs.core.MultivaluedMap<String,String> headers,
 PropertiesDelegate propertiesDelegate,
 InputStream inputStream,
 MessageBodyWorkers workers,
 Iterable<javax.ws.rs.ext.ReaderInterceptor> readerInterceptors,
 boolean translateNce,
 InjectionManager injectionManager)

Constructs a new executor to read given type from provided entityStream.

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.

readerInterceptors - Reader interceptor that are to be used to intercept the reading of an entity. The interceptors will be executed in the same order as given in this parameter.

translateNce - if true, the NoContentException thrown by a selected message body reader will be translated into a BadRequestException as required by

injectionManager - injection manager.

Method Details

proceed

public Object proceed()
               throws IOException

Starts the interceptor chain execution.

Specified by:

proceed in interface javax.ws.rs.ext.ReaderInterceptorContext

Returns:

an entity read from the stream.

Throws:

IOException

getInputStream

public InputStream getInputStream()

Specified by:

getInputStream in interface javax.ws.rs.ext.ReaderInterceptorContext

setInputStream

public void setInputStream(InputStream is)

Specified by:

setInputStream in interface javax.ws.rs.ext.ReaderInterceptorContext

getHeaders

public javax.ws.rs.core.MultivaluedMap<String,String> getHeaders()

Specified by:

getHeaders in interface javax.ws.rs.ext.ReaderInterceptorContext

getProcessedCount

int getProcessedCount()

Get number of processed interceptors.

Returns:

number of processed interceptors.

getInjectionManager

public InjectionManager getInjectionManager()

Description copied from interface: InjectionManagerSupplier

Get injection manager.

Specified by:

getInjectionManager in interface InjectionManagerSupplier

Returns:

injection manager.

closeableInputStream

public static InputStream closeableInputStream(InputStream inputStream)

Make the InputStream able to close.

The purpose of this utility method is to undo effect of ReaderInterceptorExecutor.UnCloseableInputStream.

Parameters:

inputStream - Potential ReaderInterceptorExecutor.UnCloseableInputStream to undo its effect

Returns:

Input stream that is possible to close
