org.cougaar.core.component.PropagatingServiceBroker
| PropagatingServiceBroker | | public class PropagatingServiceBroker extends ServiceBrokerSupport (Code) | | A service broker which implements not just a local SB, but also
a pass-through to another (presumably higher-level) SB.
|
| Method Summary | |
| protected void | connectToDelegate(ServiceBroker d)
| | protected void | destroy()
Disconnect this propagating service broker from its parent.
This method removes the revokation listeners, which allows
the broker to be garbage-collected.
The expected usage is for the Container to have a private
static inner-class that is a subclass of this class. | | protected void | disconnectFromDelegate(ServiceBroker d)
| | public Iterator | getCurrentServiceClasses()
gets the currently available services for this context. | | protected ServiceBroker | getDelegate()
| | public ServiceResult | getService(int requestorId, ComponentDescription requestorDesc, Object requestor, Class serviceClass, ServiceRevokedListener srl, boolean recordInView)
get an instance of the requested service from a service provider associated
with this context. | | public boolean | hasService(Class serviceClass)
| | public void | releaseService(int requestorId, ComponentDescription requestorDesc, Object requestor, Class serviceClass, Object service, boolean recordInView)
| | public void | revokeService(Class serviceClass, ServiceProvider serviceProvider)
|
| destroy | | protected void destroy()(Code) | | Disconnect this propagating service broker from its parent.
This method removes the revokation listeners, which allows
the broker to be garbage-collected.
The expected usage is for the Container to have a private
static inner-class that is a subclass of this class. The
subclass should has an added method, "void myDestroy()",
which simply calls "destroy()":
private static class MyPropSB
extends PropagatingServiceBroker {
public MyPropSB(BindingSite sb) { super(sb); }
private void myDestroy() { super.destroy(); }
}
This allows the container to call "myDestroy()" during its
"unload()", but still hide this method from the child
components (due to the private class access).
|
| getCurrentServiceClasses | | public Iterator getCurrentServiceClasses()(Code) | | gets the currently available services for this context.
This version copies the keyset to keep the iterator safe, so don't be doing this
too often.
|
| hasService | | public boolean hasService(Class serviceClass)(Code) | | is the service currently available in this broker or in the Delegate? *
