      public abstract class Resource_ImplBase
      extends Object
      implements Resource

  Implementation base class for `Resource`s. Provides access to resource metadata and the UIMA Context, which in turn provides access to framework facilities such as logging and resource management.

  - ### Method Detail

    - #### 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 `Resource`
      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:
        `multi-thread safe, given that each instance of this class is only called on one thread, once. The critical parts that update shared information (in shared uima context) are inside a synchronize block`

    - #### destroy

          public void destroy()

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

    - #### getMetaData

          public ResourceMetaData getMetaData()

      Description copied from interface: `Resource`
      Gets the metadata that describes this `Resource`.
      Specified by:
        `getMetaData` in interface `Resource`
      Returns:
        an object containing all metadata for this resource.
      See Also:
        `Resource.getMetaData()`

    - #### setMetaData

          protected void setMetaData(ResourceMetaData aMetaData)

      Sets the `ResourceMetaData` object associated with this `Resource`. Any previously existing metadata will be replaced.

      Resource subclasses should call this method during initialization in order to set the metadata before any calls to `getMetaData()` are made.

      Parameters:
        `aMetaData` - metadata to assign to this `Resource`

    - #### getLogger

          public Logger getLogger()

      Get the logger for this UIMA framework class. Note that this is NOT the user's logger in the UimaContext
      Specified by:
        `getLogger` in interface `Resource`
      Returns:
        this Resource's logger

    - #### setLogger

          public void setLogger(Logger aLogger)

      Set the logger in the current UimaContext for use by user annotators.
      Specified by:
        `setLogger` in interface `Resource`
      Parameters:
        `aLogger` - the logger for this Resource to use

    - #### getResourceManager

          public ResourceManager getResourceManager()

      Description copied from interface: `Resource`
      Gets the `ResourceManager` that this Resource uses to locate other Resources.
      Specified by:
        `getResourceManager` in interface `Resource`
      Returns:
        the ResourceManager
      See Also:
        `Resource.getResourceManager()`

    - #### getUimaContext

          public UimaContext getUimaContext()

      Description copied from interface: `Resource`
      Gets the UIMA Context for this Resource. This can be used to access external resources or facilities such as the Logger.
      Specified by:
        `getUimaContext` in interface `Resource`
      Returns:
        the UimaContext for use by this Resource

    - #### getUimaContextAdmin

          public UimaContextAdmin getUimaContextAdmin()

      Gets the Admin interface to this Resource's UimaContext.
      Specified by:
        `getUimaContextAdmin` in interface `Resource`
      Returns:
        the administrative interface to this Resource's UimaContext

    - #### getCasManager

          public CasManager getCasManager()

      Get the CasManager for this Resource. The CasManager manages the creation and pooling of CASes.
      Returns:
        the CasManager

    - #### getRelativePathResolver

          public RelativePathResolver getRelativePathResolver(Map<String,Object> aAdditionalParams)
