[Java] Class ParallelArrayWithLongMapping

java.lang.Object

      groovyx.gpars.extra166y.ParallelArrayWithLongMapping

public abstract class ParallelArrayWithLongMapping
extends OPap

A prefix view of ParallelArray that causes operations to apply to mappings of elements, not to the elements themselves. Instances of this class may be constructed only via prefix methods of ParallelArray or its other prefix classes.
