AnalysisComponent
- Direct Known Subclasses:
XmlDetagger
public abstract class CasAnnotator_ImplBase extends Annotator_ImplBase
Base class to be extended by Annotators that use theCAS
interface. An Annotator is anAnalysisComponent
that may modify its input CAS, but never creates any new CASes as output.

getRequiredCasInterface
public Class<CAS> getRequiredCasInterface()
Description copied from interface:AnalysisComponent
Returns the specific CAS interface that this AnalysisComponent requires the framework to pass to itsAnalysisComponent.process(AbstractCas)
method.- Returns:
- the required CAS interface. This must specify a subtype of
AbstractCas
.
-
process
public final 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 asAnalysisComponent.hasNext()
is called and returns false or untilprocess
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 theAnalysisComponent.getRequiredCasInterface()
method.- Throws:
AnalysisEngineProcessException
- if a problem occurs during processing
-
process
public abstract void process(CAS aCAS) throws AnalysisEngineProcessException
Inputs a CAS to the AnalysisComponent. This method should be overriden by subclasses to perform analysis of the CAS.- Parameters:
aCAS
- A CAS that this AnalysisComponent should process.- Throws:
AnalysisEngineProcessException
- if a problem occurs during processing
-
typeSystemInit
public void typeSystemInit(TypeSystem aTypeSystem) throws AnalysisEngineProcessException
Informs this annotator that the CAS TypeSystem has changed. The Analysis Engine calls this method immediately following the call toAnalysisComponent_ImplBase.initialize(org.apache.uima.UimaContext)
, and will call it again whenever the CAS TypeSystem changes.In this method, the Annotator should use the
TypeSystem
to resolve the names of Type and Features to the actualType
andFeature
objects, which can then be used during processing.- Parameters:
aTypeSystem
- the new type system to use as input to your initialization- Throws:
AnalysisEngineProcessException
- if the provided type system is missing types or features required by this annotator
