    public interface CasObjectProcessor

extends CasProcessor

Interface for CAS Processors that want to use the full `CAS` implementation.

Method Summary
`void` | `processCas(CAS aCAS)` Process a single CAS.
`void` | `processCas(CAS[] aCASes)` Processes multiple CASes.
`void` | `typeSystemInit(TypeSystem aTypeSystem)` Informs this CasConsumer that the CAS TypeSystem has changed.

Method Detail

### processCas

    void processCas(CAS aCAS)
                    throws ResourceProcessException

  Process a single CAS.

  Parameters:
    `aCAS` - the CAS to be processed. Additional information may be added to this CAS (if this CAS processor is not `read-only`).
  Throws:
    `ResourceProcessException` - if processing fails

### processCas

    void processCas(CAS[] aCASes)
                    throws ResourceProcessException

  Processes multiple CASes.

  Parameters:
    `aCASes` - an array of CASes to be processed. Additional information may be added to these CASes (if this CAS processor is not `read-only`).
  Throws:
    `ResourceProcessException` - if processing fails for any of the CASes

### typeSystemInit

    void typeSystemInit(TypeSystem aTypeSystem)
                        throws ResourceInitializationException

  Informs this CasConsumer that the CAS TypeSystem has changed. The CPM calls this method prior to initiating collection processing, and will call it again whenever the CAS TypeSystem changes.

  In this method, the CasConsumer should use the `TypeSystem` to resolve the names of Type and Features to the actual `Type` and `Feature` objects, which can then be used during processing.

  Throws:
    `ResourceInitializatinException` - if the type system is not compatible with this Cas Consumer
    `ResourceInitializationException`
