          org.apache.uima.analysis_component.JCasAnnotator_ImplBase

All Implemented Interfaces:

AnalysisComponent

public abstract class JCasAnnotator_ImplBase
extends Annotator_ImplBase

Base class to be extended by Annotators that use the JCas interface. An Annotator is an AnalysisComponent that may modify its input CAS, but never creates any new CASes as output.

Constructor Summary

JCasAnnotator_ImplBase()

Method Summary

Class<JCas>	getRequiredCasInterface() Returns the specific CAS interface that this AnalysisComponent requires the framework to pass to its AnalysisComponent.process(AbstractCas) method.
void	process(AbstractCas aCAS) Inputs a CAS to the AnalysisComponent.
abstract void	process(JCas aJCas) This method should be overriden by subclasses.

Method Detail

getRequiredCasInterface

public Class<JCas> getRequiredCasInterface()

Description copied from interface: AnalysisComponent

Returns the specific CAS interface that this AnalysisComponent requires the framework to pass to its AnalysisComponent.process(AbstractCas) method.

Returns:

the required CAS interface. This must specify a subtype of AbstractCas.

process

public void process(AbstractCas aCAS)
             throws AnalysisEngineProcessException

Description copied from interface: AnalysisComponent

Inputs a CAS to the AnalysisComponent. The AnalysisComponent "owns" this CAS until such time as AnalysisComponent.hasNext() is called and returns false or until process is called again (see class description).

Parameters:

aCAS - A CAS that this AnalysisComponent should process. The framework will ensure that aCAS implements the specific CAS interface specified by the AnalysisComponent.getRequiredCasInterface() method.

Throws:

AnalysisEngineProcessException - if a problem occurs during processing

process

public abstract void process(JCas aJCas)
                      throws AnalysisEngineProcessException

This method should be overriden by subclasses. Inputs a JCAS to the AnalysisComponent. The AnalysisComponent "owns" this JCAS until such time as Annotator_ImplBase.hasNext() is called and returns false (see AnalysisComponent for details).

Parameters:

aJCas - a JCAS that this AnalysisComponent should process.

Throws:

AnalysisEngineProcessException - if a problem occurs during processing
