DGCAckHandler

Class Overview

Holds strong references to a set of remote objects, or live remote references to remote objects, after they have been marshalled (as remote references) as parts of the arguments or the result of a remote invocation. The purpose is to prevent remote objects or live remote references that might otherwise be determined to be unreachable in this VM from being locally garbage collected before the receiver has had an opportunity to register the unmarshalled remote references for DGC. The references are held strongly until an acknowledgment has been received that the receiver has had an opportunity to process the remote references or until a timeout has expired. For remote references sent as parts of the arguments of a remote invocation, the acknowledgment is the beginning of the response indicating completion of the remote invocation. For remote references sent as parts of the result of a remote invocation, a UID is included as part of the result, and the acknowledgment is a transport-level "DGCAck" message containing that UID.

[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.
