Activation

Class Overview

The Activator facilitates remote object activation. A "faulting" remote reference calls the activator's activate method to obtain a "live" reference to a activatable remote object. Upon receiving a request for activation, the activator looks up the activation descriptor for the activation identifier, id, determines the group in which the object should be activated and invokes the activate method on the object's activation group (described by the remote interface ActivationInstantiator). The activator initiates the execution of activation groups as necessary. For example, if an activation group for a specific group identifier is not already executing, the activator will spawn a child process for the activation group.

The activator is responsible for monitoring and detecting when activation groups fail so that it can remove stale remote references from its internal tables.

Summary

[Expand] Inherited Methods

From class java.lang.Object Object clone() Creates and returns a copy of this object. boolean equals(Object obj) Indicates whether some other object is "equal to" this one. void finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. final Class<?> getClass() Returns the runtime class of this Object. int hashCode() Returns a hash code value for the object. final void notify() Wakes up a single thread that is waiting on this object's monitor. final void notifyAll() Wakes up all threads that are waiting on this object's monitor. String toString() Returns a string representation of the object. final void wait() Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object. final void wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed. final void wait(long timeout) Causes the current thread to wait until either another thread invokes the notify() method or the notifyAll() method for this object, or a specified amount of time has elapsed.
