org.rioproject.opstring.OperationalStringManager.decrement()
Decrement (decrease the number of) and remove a specific ServiceBean instance from the OperationalString. @param instance The ServiceBeanInstance @param mandate The mandate parameter is processed as follows:
- If set to {@code false}, and the number of service instances running is greater then the number of services to maintain, the number of services to maintain will be decremented by 1.
- If set to {@code false}, and the number of running service is equal to the number of services to maintain, the decrement will not be allowed.
@param destroy If true, destroy the ServiceBean upon decrementing, otherwisejust remove the service instance from being a managed service. @throws OperationalStringException If the ServiceElement is not beingmanaged by the {@code OperationalStringManager} @throws RemoteException If communication errors occur
