Class LinearRequestProcessor

java.lang.Object
  org.glassfish.jersey.process.internal.LinearRequestProcessor

All Implemented Interfaces:

com.google.common.base.Function<Request,Pair<Request,com.google.common.base.Optional<Inflector<Request,Response>>>>, RequestProcessor, Stage<Request,com.google.common.base.Optional<Inflector<Request,Response>>>

public class LinearRequestProcessor
extends java.lang.Object
implements RequestProcessor

A composite linear acceptor request processor.

When invoked, the supplied data are first transformed by the nested linear stage chain. Once a terminal stage is reached a continuation is returned with the transformed request on the left side and the inflector (optionally) provided by the terminal stage on the right side.

Constructor Detail

LinearRequestProcessor

public LinearRequestProcessor(@Stage.Root
                              LinearAcceptor rootAcceptor,
                              org.glassfish.hk2.Factory<StagingContext<Request>> contextProvider)

Construct a linear acceptor request processor.

Parameters:

rootAcceptor - head of the nested linear stage chain to be run.

contextProvider - provider of the staging context to be invoked before and after each stage is applied.

Method Detail

apply

public Pair<Request,com.google.common.base.Optional<Inflector<Request,Response>>> apply(Request request)

Traverse through the nested request stages and apply request transformations until a terminal stage providing a request-to-response inflector is reached. If the terminal stage does not provide an inflector, the inflector returned on the right side of the continuation will be absent.

This implementation transforms the request using a nested linear stage chain. Once a terminal stage is reached a continuation is returned with the transformed request on the left side and the inflector (optionally) provided by the terminal stage on the right side.

Specified by:

apply in interface com.google.common.base.Function<Request,Pair<Request,com.google.common.base.Optional<Inflector<Request,Response>>>>

Specified by:

apply in interface RequestProcessor

Specified by:

apply in interface Stage<Request,com.google.common.base.Optional<Inflector<Request,Response>>>

Parameters:

request - request data to be transformed

Returns:

continuation with the transformed request on the left side and the (optional) request-to-response inflector on the right side.
