  `Object`
  `getService(BeanContextServices bcs, Object requestor, Class<?> serviceClass, Object serviceSelector)`
  Invoked by `BeanContextServices`, this method requests an instance of a service from this `BeanContextServiceProvider`.
  `void`
  `releaseService(BeanContextServices bcs, Object requestor, Object service)`
  Invoked by `BeanContextServices`, this method releases a nested `BeanContextChild`'s (or any arbitrary object associated with a `BeanContextChild`) reference to the specified service.
  `void`
  `serviceRevoked(BeanContextServiceRevokedEvent bcsre)`
  The service named has been revoked. getService requests for this service will no longer be satisfied.

  - ### 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.
