Class SocketCasProcessorDeployer

java.lang.Object

org.apache.uima.collection.impl.cpm.container.deployer.socket.SocketCasProcessorDeployer

All Implemented Interfaces:

CasProcessorDeployer

public class SocketCasProcessorDeployer
extends Object
implements CasProcessorDeployer

Reference implementation of the CasProcessorDeployer component responsible for launch and termination of the fenced CasProcessor. It uses a plug-in ProcessControllerAdapter object to delegate launch requests from the CPM to the external application.

Method Detail

deployCasProcessor

public ProcessingContainer deployCasProcessor(List aCasProcessorList,
                                              CPMEngine aEngine,
                                              boolean redeploy)
                                       throws ResourceConfigurationException

Deploys integrated Cas Processor. Number of instances this routine actually deploys depends on number of processing threads defined in the CPE descriptor. There is one instance per processing thread created here. The aCasProcessorList contains instantiated Cas Processors. These are instantiated by the CPEFactory.

Parameters:

aCasProcessorList - - list containing instantiated Cas Processors

redeploy - - true when redeploying failed Cas Processor

Returns:

- ProcessingContainer containing pool of CasProcessors

Throws:

ResourceConfigurationException

deployCasProcessor

public ProcessingContainer deployCasProcessor(List aCasProcessorList,
                                              boolean redeploy)
                                       throws ResourceConfigurationException

Uses ProcessControllerAdapter instance to launch fenced CasProcessor.

Specified by:

deployCasProcessor in interface CasProcessorDeployer

Parameters:

aCasProcessorList - - list of Cas Processors to deploy

redeploy - - true if the Cas Processor is being redeployed as part of the recovery, false otherwise

Returns:

ProcessingContainer managing deployed Cas Processors

Throws:

ResourceConfigurationException - - failed to deploy Cas Processor

deployCasProcessor

public void deployCasProcessor(ProcessingContainer aProcessingContainer)
                        throws ResourceConfigurationException

Uses ProcessControllerAdapter instance to launch fenced CasProcessor.

Specified by:

deployCasProcessor in interface CasProcessorDeployer

Parameters:

aProcessingContainer - - ProcessingContainer managing deployed Cas Processor to redeploy

Throws:

ResourceConfigurationException - - failed to deploy Cas Processor

undeploy

public void undeploy(URL aURL)
              throws CasProcessorDeploymentException

Specified by:

undeploy in interface CasProcessorDeployer

Throws:

CasProcessorDeploymentException

undeploy

public void undeploy()
              throws CasProcessorDeploymentException

Specified by:

undeploy in interface CasProcessorDeployer

Throws:

CasProcessorDeploymentException
