Class CasObjectNetworkCasProcessorImpl

java.lang.Object

org.apache.uima.collection.impl.cpm.container.CasObjectNetworkCasProcessorImpl

All Implemented Interfaces:

org.apache.uima.collection.base_cpm.CasObjectProcessor, org.apache.uima.collection.base_cpm.CasProcessor

public class CasObjectNetworkCasProcessorImpl
extends Object
implements org.apache.uima.collection.base_cpm.CasObjectProcessor

Implementation of the CasObjectProcessor interface used for both Local and Remote CasObjectProcessors. This objects plugs in a transport object defined in the CPE Descriptor and uses it to delegate analysis of CAS to a remote AE.

Constructor Detail

CasObjectNetworkCasProcessorImpl

public CasObjectNetworkCasProcessorImpl(org.apache.uima.collection.metadata.CpeCasProcessor aCasProcessor)
                                 throws org.apache.uima.resource.ResourceConfigurationException

Using information from the CPE descriptor creates an instance of Transport class. The transport class will delegate analysis of CAS to a remote object.

Parameters:

aCasProcessor - - Cas Process configuration from the CPE descriptor

Throws:

org.apache.uima.resource.ResourceConfigurationException - the resource configuration exception

Method Detail

getEndpoint

public URL getEndpoint()

Creates URL object containing service endpoint info ( host and port).

Returns:

URL

connect

public void connect(URL aURL)
             throws org.apache.uima.resource.ResourceInitializationException

Connects to a service endpoint defined in the given URL.

Parameters:

aURL - - contains service endpoint info (hots and port)

Throws:

org.apache.uima.resource.ResourceInitializationException - wraps SocketException

processCas

public void processCas(org.apache.uima.cas.CAS aCAS)
                throws org.apache.uima.resource.ResourceProcessException

Specified by:

processCas in interface org.apache.uima.collection.base_cpm.CasObjectProcessor

Parameters:

aCAS - CAS to be analyzed

Throws:

org.apache.uima.resource.ResourceProcessException - wraps Exception, SocketException
