  • Method Details

    • 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.
