All Implemented Interfaces:

AWObject

public final class AWCheckoutManager
extends AWBaseObject

This class implements a check out mechanism that allows threads to do an exclusive "checkout" on a key value. Threads that attempt to check out a key value that is already checked out will wait until the key is checked back in and available. Threads that have waited beyond the timeout period will throw an exception.
