extra166y.ParallelDoubleArrayWithDoubleMapping
- Direct Known Subclasses:
ParallelDoubleArrayWithFilter
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 ParallelDoubleArray or its other prefix classes.
