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The service named has been revoked.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.
