Examples of java.rmi.activation.ActivationSystem

java.rmi.activation.ActivationSystem
The ActivationSystem provides a means for registering groups and "activatable" objects to be activated within those groups. The ActivationSystem works closely with the Activator, which activates objects registered via the ActivationSystem, and the ActivationMonitor, which obtains information about active and inactive objects, and inactive groups. @author Ann Wollrath @version 1.19, 11/17/05 @see Activator @see ActivationMonitor @since 1.2
