Method Detail

getCurrentServiceSelectors

public java.util.Iterator getCurrentServiceSelectors(BeanContextServices bcs,
                                                     java.lang.Class serviceClass)
                                              throws gnu.classpath.NotImplementedException

Description copied from interface: BeanContextServiceProvider

Get a list of valid service selectors for the specified service class. This method is called from BeanContextServices.getCurrentServiceSelectors().

If the specified service class does not have a finite number of valid service selectors, it should return null. If it takes a general Integer parameter, for example, you may as well return null or the poor soul who called this method will be iterating all day.

If it has no valid service selectors, it should still return an empty Iterator.

Specified by:

getCurrentServiceSelectors in interface BeanContextServiceProvider

getService

public java.lang.Object getService(BeanContextServices bcs,
                                   java.lang.Object requestor,
                                   java.lang.Class serviceClass,
                                   java.lang.Object serviceSelector)
                            throws gnu.classpath.NotImplementedException

Description copied from interface: BeanContextServiceProvider

Get a service. Called from BeanContextServices.getService().

If the requested service class is not available, or if this BeanContextServiceProvider chooses not honor the request for some reason, then this method will return null.

This method may throw unchecked exceptions, so watch out.

Specified by:

getService in interface BeanContextServiceProvider

releaseService

public void releaseService(BeanContextServices bcs,
                           java.lang.Object requestor,
                           java.lang.Object service)
                    throws gnu.classpath.NotImplementedException

Description copied from interface: BeanContextServiceProvider

Release the service.

Called by BeanContextServices.releaseService().

Most BeanContextServiceProviders won't have to do anything here.

Specified by:

releaseService in interface BeanContextServiceProvider

---

serviceRevoked

public void serviceRevoked(BeanContextServiceRevokedEvent bcsre)
                    throws gnu.classpath.NotImplementedException

Description copied from interface: BeanContextServiceRevokedListener

Called by BeanContextServices.revokeService() to indicate that a service has been revoked. If you have a reference to such a service, it should be discarded and may no longer function properly. getService() will no longer work on the specified service class after this event has been fired.

Specified by:

serviceRevoked in interface BeanContextServiceRevokedListener
