Class ResponseProcessor<DATA>

java.lang.Object
  org.glassfish.jersey.process.internal.ResponseProcessor<DATA>

Type Parameters:

DATA - processed data type.

All Implemented Interfaces:

java.lang.Runnable

public abstract class ResponseProcessor<DATA>
extends java.lang.Object
implements java.lang.Runnable

Processes result of the request transformation (successful or not). The response processor also represents the ultimate future request-to-response transformation result.

A response processor is invoked when the request-to-response transformation processing is finished. When invoked, the response processor retrieves the transformation result. If the transformation was successful and a response instance is returned, the response processor runs the response instance through the chain of registered response filters and returns a result once finished. In case the request transformation finished with an exception, the response processor tries to map the exception to a response using the registered exception mappers and, if successful, runs the mapped response instance through the chain of registered response filters and returns a result once finished. In case the exception was not mapped to a response, the exception is presented as the ultimate request-to-response transformation result.

Create new response processor for a given request / response message exchange.

Parameters:

callback - the invocation callback to be invoked once the response processing has finished.

inflectedResponse - inflected response data future.

processedResponse - settable future that will be used to set the response processing result.

respondingCtxProvider - responding context provider.

scopeInstance - the instance of the request scope this processor belongs to.

requestScope - Jersey request scope.

exceptionMappersProvider - exception mappers provide.

Method Detail

run

public void run()

Specified by:

run in interface java.lang.Runnable

convertResponse

protected abstract DATA convertResponse(Response exceptionResponse)

Convert an exception-mapped JAX-RS response to supported processing data type.

Parameters:

exceptionResponse - a processing exception mapped to a JAX-RS response.

Returns:

JAX-RS exception-mapped response transformed to supported processing data type.
