## Class RootUimaContext_impl

- java.lang.Object
- - org.apache.uima.impl.UimaContext_ImplBase
  - - org.apache.uima.impl.RootUimaContext_impl

- All Implemented Interfaces:
    UimaContext, UimaContextAdmin

      public class RootUimaContext_impl
      extends UimaContext_ImplBase

  Implementation of the root `UimaContext`. UIMA Contexts are arranged in a tree structure corresponding to the nested structure of the components in a CPE or Aggregate AE. The root UimaContext has direct references to shared components such as the ResourceManager and ConfigurationManager. The children UimaContexts reference these through the root.

      Description copied from class: `UimaContext_ImplBase`
      (non-Javadoc)
      Specified by:
        `getExternalOverrides` in interface `UimaContext`
      Specified by:
        `getExternalOverrides` in interface `UimaContextAdmin`
      Overrides:
        `getExternalOverrides` in class `UimaContext_ImplBase`
      Returns:
        the Settings object
      See Also:
        `UimaContextAdmin.getExternalOverrides()`

    - #### setExternalOverrides

          public void setExternalOverrides(Settings externalOverrides)

      Description copied from class: `UimaContext_ImplBase`
      (non-Javadoc)
      Specified by:
        `setExternalOverrides` in interface `UimaContextAdmin`
      Overrides:
        `setExternalOverrides` in class `UimaContext_ImplBase`
      Parameters:
        `externalOverrides` - the external overrides settings
      See Also:
        `UimaContextAdmin.setExternalOverrides(org.apache.uima.util.Settings)`

    - #### initializeRoot

          public void initializeRoot(Logger aLogger,
                                     ResourceManager aResourceManager,
                                     ConfigurationManager aConfigurationManager)

      Description copied from interface: `UimaContextAdmin`
      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.

    - #### getLogger

          public Logger getLogger()

      Description copied from interface: `UimaContext`
      Gets the `Logger` to which log output will be sent. UIMA components should use this facility rather than writing to their own log files (or to stdout).
      Returns:
        an instance of a logger for use by this annotator.
      See Also:
        `AnnotatorContext.getLogger()`

    - #### setLogger

          public void setLogger(Logger aLogger)

      Description copied from interface: `UimaContextAdmin`
      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.

    - #### getResourceManager

          public ResourceManager getResourceManager()

      Gets the ResourceManager used by this UimaContext to locate and access external resources
      Returns:
        the ResourceManager

    - #### getConfigurationManager

          public ConfigurationManager getConfigurationManager()

      Description copied from interface: `UimaContextAdmin`
      Gets the ConfigurationManager instance used by this UimaContext to resolve configuration parameter resource accesses.
      Returns:
        the ConfigurationManager instance for this UimaContext

    - #### getInstrumentationFacility

          public InstrumentationFacility getInstrumentationFacility()

      Gets the InstrumentationFacility to be used within this AnalysisEngine.
      Returns:
        the InstrumentationFacility to be used within this AnalysisEngine

    - #### setProcessTrace

          public void setProcessTrace(ProcessTrace aProcessTrace)

      Sets the current ProcessTrace object, which will receive trace events generated by the InstrumentationFacility.

      This method is to be called from the Analysis Engine, not the Annotator, so it is not part of the AnnotatorContext interface.

      Parameters:
        `aProcessTrace` - the ProcessTrace object to receive trace events

    - #### setSession

          public void setSession(Session aSession)

      Description copied from interface: `UimaContextAdmin`
      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

    - #### getSession

          public Session getSession()

      Description copied from interface: `UimaContext`
      Returns the Session object, which can be used to store data that pertains to a particular client session. All data that must persist across requests must be stored in the Session object and NOT in component instance variables. In some service deployments, a single component instance may serve multiple clients. In that case, the service wrapper may provide a different Session object for each client, and this method would return the appropriate Session object for the component to use for the current call.

      Note that Session support is NOT implemented in any of the service wrappers (Vinci, SOAP) currently provided in the UIMA SDK.

      Returns:
        the current Session object

    - #### getRootContext

          public UimaContextAdmin getRootContext()

      Get the Root Context
      Returns:
        root context
