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
- 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- The service named has been revoked.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.
