Public Methods

public Iterator getCurrentServiceSelectors (BeanContextServices bcs, Class serviceClass)

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.

Parameters
bcs the BeanContextServices for this request
serviceClass the specified service
Returns
  • the current service selectors for the specified serviceClass

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

Invoked by BeanContextServices, this method requests an instance of a service from this 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

public 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.

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

public void serviceRevoked (BeanContextServiceRevokedEvent bcsre)

The service named has been revoked. getService requests for this service will no longer be satisifed.

Parameters
bcsre the BeanContextServiceRevokedEvent received by this listener.
