## org.apache.uima.collection.base_cpm
Class CasDataConsumer_ImplBase

    java.lang.Object
      org.apache.uima.resource.Resource_ImplBase
          org.apache.uima.resource.ConfigurableResource_ImplBase
              org.apache.uima.collection.base_cpm.CasDataConsumer_ImplBase

All Implemented Interfaces:
  CasDataConsumer, CasDataProcessor, CasProcessor, ConfigurableResource, Resource

    public abstract class CasDataConsumer_ImplBase

extends ConfigurableResource_ImplBase
implements CasDataConsumer

Base class from which to extend when writing CAS Consumers that use the `CasData` interface to access the CAS.

### CasDataConsumer_ImplBase

    public CasDataConsumer_ImplBase()

Method Detail

### initialize

    public boolean initialize(ResourceSpecifier aSpecifier,
                              Map aAdditionalParams)
                       throws ResourceInitializationException

  Called by the framework to initialize this CAS Consumer. Subclasses should NOT override this method; instead they should override the zero-argument `initialize()` method and access metadata via the `getProcessingResourceMetaData()` method. This method is non-final only for legacy reasons.

  Specified by:
    `initialize` in interface `Resource`
  Overrides:
    `initialize` in class `Resource_ImplBase`
  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(org.apache.uima.resource.ResourceSpecifier, java.util.Map)`

### initialize

    public void initialize()
                    throws ResourceInitializationException

  This method is called during initialization, and does nothing by default. Subclasses should override it to perform one-time startup logic.

  Throws:
    `ResourceInitializationException` - if a failure occurs during initialization.

### 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()`

### isStateless

    public boolean isStateless()

  Description copied from interface: `CasProcessor`
  Gets whether this is a stateless CAS Processor. Stateless CAS Processors do not maintain any data between calls to their process methods.

  Specified by:
    `isStateless` in interface `CasProcessor`
  Returns:
    true if this CAS processor is stateless, false if it is stateful.
  See Also:
    `CasProcessor.isStateless()`

### isReadOnly

    public boolean isReadOnly()

  Description copied from interface: `CasProcessor`
  Gets whether this is a read-only CAS Processor, which does not modify the CAS.

  Specified by:
    `isReadOnly` in interface `CasProcessor`
  Returns:
    true if this CAS processor does not modify the CAS, false if it does.
  See Also:
    `CasProcessor.isReadOnly()`

### getProcessingResourceMetaData

    public ProcessingResourceMetaData getProcessingResourceMetaData()

  Description copied from interface: `CasProcessor`
  Gets the metadata that describes this `CasProcesor`.

  Specified by:
    `getProcessingResourceMetaData` in interface `CasProcessor`
  Returns:
    an object containing all metadata for this CasProcessor
  See Also:
    `CasProcessor.getProcessingResourceMetaData()`
