Class Summary

Class	Description
AbstractSpinningCondition	Created by jcairns on 2/18/16.
AtomicSequence	This implements the CAS approach to lock-free synchronization, in other words a sequence of atomic changes.
ConcurrentStack<N>	Concurrent "lock-free" version of a stack.
DisruptorBlockingQueue<E>	A fixed length blocking queue based on the principles of: http://disruptor.googlecode.com/files/Disruptor-1.0.pdf This class could be used where ArrayBlockingQueue would be otherwise.
MPMCBlockingQueue<E>	Added for benchmarking comparison - not for production use
MultithreadConcurrentQueue<E>	This is the disruptor implemented for multiple simultaneous reader and writer threads.
PushPullBlockingQueue<E>	Single thread implementation of disruptor
PushPullConcurrentQueue<E>	Tuned version of Martin Thompson's push pull queue Transfers from a single thread writer to a single thread reader are orders of nanoseconds (3-5) This code is optimized and tested using a 64bit HotSpot JVM on an Intel x86-64 environment.
SequenceLock	http://www.hpl.hp.com/techreports/2012/HPL-2012-68.pdf Created by jcairns on 2/12/16.
