- org.apache.uima.analysis_component.AnalysisComponent_ImplBase
- - org.apache.uima.analysis_component.Annotator_ImplBase

All Implemented Interfaces:

AnalysisComponent

Direct Known Subclasses:

CasAnnotator_ImplBase, JCasAnnotator_ImplBase
```
public abstract class Annotator_ImplBase
extends AnalysisComponent_ImplBase
```
Base class for all annotators. An Annotator is an AnalysisComponent that may modify its input CAS, but never creates any new CASes as output. Typically, annotators should not extend this class directly, but instead extend CasAnnotator_ImplBase or JCasAnnotator_ImplBase depending on which CAS interface they wish to use.

public Annotator_ImplBase()
```
- Method Detail
  - getCasInstancesRequired
```
public final int getCasInstancesRequired()
```
    Returns 0, since annotators are not allowed to create new CAS instances. Only CasMultipliers are allowed to do this.
    
    Returns:
    
    the number of CAS instances required by this AnalysisComponent.
  - hasNext
```
public final boolean hasNext()
                      throws AnalysisEngineProcessException
```
    Returns false, since annotators are not allowed to create new CAS instances. Only CasMultipliers are allowed to do this.
    
    Returns:
    
    true if this AnalysisComponent has another CAS to output, false if not.
    
    Throws:
    
    AnalysisEngineProcessException - if a problem occurs during processing
  - next
```
public final AbstractCas next()
                       throws AnalysisEngineProcessException
```
    Throws a UIMA_IllegalStateException, since annotators are not allowed to create new CAS instances. Only CasMultipliers are allowed to do this.
    
    Returns:
    
    the next output CAS.
    
    Throws:
    
    AnalysisEngineProcessException - if a problem occurs during processing
