AtomicLong Provides lock-free atomic read/write utility for a long value. The atomic classes found in this package are meant to replicate the java.util.concurrent.atomic package in Java by Doug Lea. The two main differences are implicit casting back to the long data type, and the use of a non-volatile inner variable. The internals of these classes contain wrapped usage of the System.Threading.Interlocked class, which is how we are able to provide atomic operation without the use of locks.
