java.lang.Object
  extended by jsr166z.forkjoin.ParallelDoubleArray.WithLongMapping
Enclosing class:
ParallelDoubleArray

public abstract static class ParallelDoubleArray.WithLongMapping
extends java.lang.Object

A modifier for parallel array operations to apply to mappings of elements to longs, not to the elements themselves
