  AbstractParallelAnyArray.OPap
      groovyx.gpars.extra166y.ParallelArrayWithMapping

public abstract class ParallelArrayWithMapping
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.
