      Initializes a root UimaContext.
      Parameters:
        `aLogger` - the logger that will be returned by this UimaContext's `UimaContext.getLogger()` method.
        `aResourceManager` - the ResourceManager that will be used by this UimaContext to locate and access external resource.
        `aConfigurationManager` - the ConfigurationManager that will be used by this UimaContext to access its configuration parameter settings.

    - #### createChild

          UimaContextAdmin createChild(String aContextName,
                                       Map<String,String> aSofaMappings)

      Creates a UimaContext that is a child of this UimaContext.
      Parameters:
        `aContextName` - a name for the new context, which must be unique with respect to all children of the parent context.
        `aSofaMappings` - mappings from child's sofa name to parent's sofa name. May be null.
      Returns:
        the Administrative interface to the UIMA Context

    - #### setLogger

          void setLogger(Logger aLogger)

      Sets the Logger for this UimaContext. If this method is not called, the default logger (`UIMAFramework.getLogger()`) will be used.
      Parameters:
        `aLogger` - the logger that will be returned by this UimaContext's `UimaContext.getLogger()` method.

    - #### setProcessTrace

          void setProcessTrace(ProcessTrace aProcessTrace)

      Sets the current ProcessTrace object, which will receive trace events generated by the InstrumentationFacility.
      Parameters:
        `aProcessTrace` - the ProcessTrace object to receive trace events

    - #### getResourceManager

          ResourceManager getResourceManager()

      Gets the ResourceManager instance used by this UimaContext to resolve external resource accesses.
      Returns:
        the ResourceManager instance for this UimaContext

    - #### getConfigurationManager

          ConfigurationManager getConfigurationManager()

      Gets the ConfigurationManager instance used by this UimaContext to resolve configuration parameter resource accesses.
      Returns:
        the ConfigurationManager instance for this UimaContext

    - #### getQualifiedContextName

          String getQualifiedContextName()

      Gets the fully-qualified name of this context. This is a slash-separated name consisting of each containing context name back to the root. It always begins and ends with a slash. For example, the context name for an annotator nested within two AnalysisEngines might look like: `/MyTopLevelAnalysisEngine/MyComponentAnalysisEngine/MyAnnotator/`.
      Returns:
        the qualified context name

    - #### setSession

          void setSession(Session aSession)

      Sets the current session object. A default Session object is created when the UimaContext is created. In a multi-client deployment, the deployment wrapper is responsible for ensuring that an appropriate Session object is installed here prior to invoking components that use this UimaContext.
      Parameters:
        `aSession` - the session object

    - #### getRootContext

          UimaContextAdmin getRootContext()

      Gets the Root Context for this Resource. This is the top-level context for the outermost aggregate component (AnalysisEngine or CollectionProcessingEngine).
      Returns:
        root context

    - #### defineCasPool

          void defineCasPool(int aSize,
                             Properties aPerformanceTuningSettings,
                             boolean aSofaAware)
                      throws ResourceInitializationException

      Defines the CAS pool that this UimaContext must support. This method must be called before `UimaContext.getEmptyCas(Class)` may be called.
      Parameters:
        `aSize` - the minimum CAS pool size required
        `aPerformanceTuningSettings` - settings, including initial CAS heap size, for the AE
        `aSofaAware` - whether the component that will receive these CASes is sofa aware. This is needed to determine which view to get. Sofa-aware components get the base view; sofa-unaware components get the default text sofa view (or whatever is mapped to it).
      Throws:
        `ResourceInitializationException` - if a CAS could not be created.

    - #### getManagementInterface

          AnalysisEngineManagement getManagementInterface()

      Gets an object that can be used to do monitoring or management of this AnalysisEngine.
      Returns:
        an object exposing a management interface to this AE

    - #### getComponentInfo

          ComponentInfo getComponentInfo()

      Gets the ComponentInfo object for this component, which can be passed to `CAS.setCurrentComponentInfo(ComponentInfo)`.
      Returns:
        the component info

    - #### getSofaMap

          Map<String,String> getSofaMap()

      Gets an unmodifiable Map containing the mapping of component sofa name to absolute sofa ID.
      Returns:
        the Sofa map for this component

    - #### returnedCAS

          void returnedCAS(AbstractCas aCAS)

      Called internally by the framework whenever the AnalysisComponent returns a CAS from its next() method or calls cas.release(). Used to monitor the number of CASes that the AnalysisComponent is using at any one time.
      Parameters:
        `aCAS` - the CAS that was returned or released

    - #### getUniqueName

          String getUniqueName()

      Returns a UUID-like unique name of this component.
      Returns:
        - unique name of this component

    - #### getExternalOverrides

          Settings getExternalOverrides()

      Gets the settings to be used for external parameter overrides
      Specified by:
        `getExternalOverrides` in interface `UimaContext`
      Returns:
        the Settings object

    - #### setExternalOverrides
