Class AWRecursiveLock

java.lang.Object
  ariba.ui.aribaweb.util.AWBaseObject
      ariba.ui.aribaweb.util.AWRecursiveLock

All Implemented Interfaces:

AWObject

public final class AWRecursiveLock
extends AWBaseObject

AWRecursiveLock allows for blocking access to a block of code to all threads but the first one to grab access. Once a thread locks this lock, it can continue running and lock it as many times as necessary (a count is incremented keeping track of the number of times). Of course, it must balance the number of calls to lock with calls to unlock else a deadlock will occur.
