    - #### initialize

          public boolean initialize(ResourceSpecifier aSpecifier,
                                    Map<String,Object> aAdditionalParams)
                             throws ResourceInitializationException

      Description copied from interface: `Resource`
      Initializes this `Resource` from a `ResourceSpecifier`. Applications do not need to call this method. It is called automatically by the `ResourceFactory` and cannot be called a second time.
      Specified by:
        `initialize` in interface `AnalysisEngine`
      Specified by:
        `initialize` in interface `Resource`
      Overrides:
        `initialize` in class `AnalysisEngineImplBase`
      Parameters:
        `aSpecifier` - specifies how to create a resource or locate an existing resource service.
        `aAdditionalParams` - a Map containing additional parameters. May be `null` if there are no parameters. Each class that implements this interface can decide what additional parameters it supports.
      Returns:
        true if and only if initialization completed successfully. Reutrns false if the given `ResourceSpecifier` is not of an appropriate type for this Resource. If the `ResourceSpecifier` is of an appropriate type but is invalid or if some other failure occurs, an exception should be thrown.
      Throws:
        `ResourceInitializationException` - if a failure occurs during initialization.
      See Also:
        `Resource.initialize(ResourceSpecifier, Map)`

    - #### initializeAnalysisComponent

          protected void initializeAnalysisComponent(Map<String,Object> aAdditionalParams)
                                              throws ResourceInitializationException

      Loads, instantiates, and initializes the AnalysisComponent contained in this AE.
      Parameters:
        `aAdditionalParams` - parameters passed to this AE's initialize method
      Throws:
        `ResourceInitializationException` - if an initialization failure occurs

    - #### destroy

          public void destroy()

      Description copied from interface: `Resource`
      Releases all resources held by this `Resource`.
      Specified by:
        `destroy` in interface `Resource`
      Overrides:
        `destroy` in class `Resource_ImplBase`
      See Also:
        `Resource.destroy()`

    - #### setResultSpecification

          public void setResultSpecification(ResultSpecification aResultSpec)

      Description copied from interface: `AnalysisEngine`
      Sets the list of output types and features that the application wants this AnalysisEngine to produce. This is only a guideline. Annotators may use this information to avoid doing unnecessary work, but they are not required to do so.
      Specified by:
        `setResultSpecification` in interface `AnalysisEngine`
      Overrides:
        `setResultSpecification` in class `AnalysisEngineImplBase`
      Parameters:
        `aResultSpec` - specifies the list of output types and features that the application is interested in.

    - #### processAndOutputNewCASes

          public CasIterator processAndOutputNewCASes(CAS aCAS)
                                               throws AnalysisEngineProcessException

      Description copied from interface: `AnalysisEngine`
      Processes a CAS, possibly producing multiple CASes as a result. The application uses the `CasIterator` interface to step through the output CASes.

      If this Analysis Engine does not produce output CASes, then the `CasIterator` will return no elements. You can check if an AnalysisEngine is capable of producing output CASes by checking the `OperationalProperties.getOutputsNewCASes()` operational property (`getAnalysisEngineMetaData().getOperationalProperties().getOutputsNewCASes()`).

      Once this method is called, the AnalysisEngine "owns" `aCAS` until such time as the `CasIterator.hasNext()` method returns false. That is, the caller should not attempt to modify or access the input CAS until it has read all of the elements from the CasIterator. If the caller wants to abort the processing before having read all of the output CASes, it may call `CasIterator.release()`, which will stop further processing from occurring, and ownership of `aCAS` will revert to the caller.

      Specified by:
        `processAndOutputNewCASes` in interface `AnalysisEngine`
      Overrides:
        `processAndOutputNewCASes` in class `AnalysisEngineImplBase`
      Parameters:
        `aCAS` - the CAS to be processed
      Returns:
        an object for iterating through any output CASes
      Throws:
        `AnalysisEngineProcessException` - if a failure occurs during processing
      See Also:
        `AnalysisEngine.processAndOutputNewCASes(CAS)`

    - #### batchProcessComplete

          public void batchProcessComplete()
                                    throws AnalysisEngineProcessException

      Description copied from interface: `AnalysisEngine`
      Notifies this AnalysisEngine that processing of a batch has completed. It is up to the caller to determine the size of a batch. Components (particularly CAS Consumers) inside this Analysis Engine may respond to this event, for example by writing data to the disk.
      Specified by:
        `batchProcessComplete` in interface `AnalysisEngine`
      Overrides:
        `batchProcessComplete` in class `AnalysisEngineImplBase`
      Throws:
        `AnalysisEngineProcessException` - if an exception occurs during processing

    - #### collectionProcessComplete

          public void collectionProcessComplete()
                                         throws AnalysisEngineProcessException

      Description copied from interface: `AnalysisEngine`
      Notifies this AnalysisEngine that processing of an entire collection has completed. It is up to the caller to determine when this has occurred. Components (particularly CAS Consumers) inside this Analysis Engine may respond to this event, for example by writing data to the disk.

      If this AnalysisEngine is an aggregate, this method will call the collectionProcessComplete method of all components of that aggregate. If the aggregate descriptor declares a `fixedFlow` or `capabilityLanguageFlow`, then the components' collectionProcessComplete methods will be called in the order specified by that flow element. Once all components in the flow have been called, any components not declared in the flow will be called, in arbitrary order. If there is no `fixedFlow` or `capabilityLanguageFlow`, then all components in the aggregate will be called in arbitrary order.

      Specified by:
        `collectionProcessComplete` in interface `AnalysisEngine`
      Overrides:
        `collectionProcessComplete` in class `AnalysisEngineImplBase`
      Throws:
        `AnalysisEngineProcessException` - if an exception occurs during processing

    - #### callAnalysisComponentProcess

          protected void callAnalysisComponentProcess(CAS aCAS)
                                               throws AnalysisEngineProcessException

      Calls the Analysis Component's process method.
      Parameters:
        `aCAS` - CAS to be processed by annotator
      Throws:
        `AnalysisEngineProcessException` - -

    - #### callAnalysisComponentNext

          protected CAS callAnalysisComponentNext()
                                           throws AnalysisEngineProcessException,
                                                  ResultNotSupportedException

      Calls the Analysis Component's next() method.
      Returns:
        CAS returned by the analysis component
      Throws:
        `AnalysisEngineProcessException` - -
        `ResultNotSupportedException` - -

    - #### reconfigure

          public void reconfigure()
                           throws ResourceConfigurationException

      Description copied from interface: `ConfigurableResource`
      Instructs this Resource to re-read its configuration parameter settings.
      Specified by:
        `reconfigure` in interface `AnalysisEngine`
      Specified by:
        `reconfigure` in interface `ConfigurableResource`
      Overrides:
        `reconfigure` in class `ConfigurableResource_ImplBase`
      Throws:
        `ResourceConfigurationException` - if the configuration is not valid
