public class AccumulatorLong
extends java.lang.Object

Accumulator Long container. Typically used in conditions where it is desireable to pass an accumulator to an inner-class and have the value accessible from outside the inner-class. (If the accumulator is to be used from different threads in a multi-threaded environment, use "AtomicLong" instead).
