public class PrimitiveLongArray
extends AbstractPrimitiveArray

A subclassable array of longs. PrimitiveLongArray is designed with semantics specifically chosen and restricted such that a "flat" memory layout of the implemented data structure would be possible on optimizing JVMs. While fully functional on all JVM implementation (of Java SE 6 and above), the semantics are such that a JVM may transparently optimise the implementation to provide a compact contiguous layout that facilitates dead-reckoning (as opposed to de-referenced) access to elements
