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 satisifed.

Specified by:

serviceRevoked in interface BeanContextServiceRevokedListener

Parameters:

bcsre - the BeanContextServiceRevokedEvent received by this listener.
