long	addAndGet(long delta) Atomically adds the given value to the current value.
boolean	compareAndSet(long expect, long update) Atomically sets the value to the given updated value only if the current value == the expected value.
long	decrementAndGet() Atomically decrements the current value by one.
long	get() Gets the current value.
long	getAndAdd(long delta) Atomically adds the given value to the current value.
long	getAndIncrement() Atomically increments the current value by one.
long	getAndSet(long newValue) Atomically sets the given value and returns the old value.
String	getName() Returns the name of this IAtomicLong instance.
long	incrementAndGet() Atomically increments the current value by one.
