Method Detail

• 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.
