| ServiceUserPlugin | | abstract public class ServiceUserPlugin extends ComponentPlugin (Code) | | This component is a convenience base class for plugins that
need to acquire services that may not be immediately available
when first started.
Records the service classes needed and attempts acquire them
on request. Also provides timer services.
Instead of using this class, consider using a
org.cougaar.core.component.ServiceAvailableListener .
|
| ServiceUserPlugin | | protected ServiceUserPlugin(Class[] serviceClasses)(Code) | | Constructor
Parameters:
serviceClasses - the service classes needed for this pluginto operate. |
| acquireServices | | protected boolean acquireServices()(Code) | | Test if all services specified in the constructor are available.
Sub-classes should call this method from their setupSubscriptions
and execute methods until it returns true. Once this method
returns true, the services should be requested and normal
operation started. Once all the services are available, this
method simply returns true. See haveServices() in
org.cougaar.core.adaptivity.ConditionServiceProvider.execute ConditionServiceProvider for a typical usage pattern.
