Class MultiBinaryLongMap.ChainedLock

  • All Implemented Interfaces:
    Enclosing class:

    protected static class MultiBinaryLongMap.ChainedLock
    extends Object
    implements Lock
    A ChainedLock is a Lock implementation that represents a composition of two component locks, parent and child. All operations on this lock will first be performed on the parent lock, and only upon successful completion be performed on the child lock.

    A ChainedLock could be used to manage multiple logical levels of concurrency control across multiple components without exposing multiple resource locks and thus imposing a locking order that reduces the possibility of introducing deadlocks.

    Note: a ChainedLock could be used to represent a chain of more than two Locks by constructing a "chain of chains".
