    - #### getService

          public Object getService(BeanContextServices bcs,
                          Object requestor,
                          Class serviceClass,
                          Object serviceSelector)

      Description copied from interface: `BeanContextServiceProvider`
      Invoked by `BeanContextServices`, this method requests an instance of a service from this `BeanContextServiceProvider`.
      Specified by:
        `getService` in interface `BeanContextServiceProvider`
      Parameters:
        `bcs` - The `BeanContextServices` associated with this particular request. This parameter enables the `BeanContextServiceProvider` to distinguish service requests from multiple sources.
        `requestor` - The object requesting the service
        `serviceClass` - The service requested
        `serviceSelector` - the service dependent parameter for a particular service, or `null` if not applicable.
      Returns:
        a reference to the requested service

    - #### releaseService

          public void releaseService(BeanContextServices bcs,
                            Object requestor,
                            Object service)

      Description copied from interface: `BeanContextServiceProvider`
      Invoked by `BeanContextServices`, this method releases a nested `BeanContextChild`'s (or any arbitrary object associated with a `BeanContextChild`) reference to the specified service.
      Specified by:
        `releaseService` in interface `BeanContextServiceProvider`
      Parameters:
        `bcs` - the `BeanContextServices` associated with this particular release request
        `requestor` - the object requesting the service to be released
        `service` - the service that is to be released

    - #### getCurrentServiceSelectors

          public Iterator getCurrentServiceSelectors(BeanContextServices bcs,
                                            Class serviceClass)

      Description copied from interface: `BeanContextServiceProvider`
      Invoked by `BeanContextServices`, this method gets the current service selectors for the specified service. A service selector is a service specific parameter, typical examples of which could include: a parameter to a constructor for the service implementation class, a value for a particular service's property, or a key into a map of existing implementations.
      Specified by:
        `getCurrentServiceSelectors` in interface `BeanContextServiceProvider`
      Parameters:
        `bcs` - the `BeanContextServices` for this request
        `serviceClass` - the specified service
      Returns:
        the current service selectors for the specified serviceClass

    - #### serviceRevoked

          public void serviceRevoked(BeanContextServiceRevokedEvent bcsre)

      Description copied from interface: `BeanContextServiceRevokedListener`
      The service named has been revoked. getService requests for this service will no longer be satisfied.
      Specified by:
        `serviceRevoked` in interface `BeanContextServiceRevokedListener`
      Parameters:
        `bcsre` - the `BeanContextServiceRevokedEvent` received by this listener.
