Class ParallelDoubleArrayWithDoubleMapping

  • Direct Known Subclasses:
    ParallelDoubleArrayWithFilter
    public abstract class ParallelDoubleArrayWithDoubleMapping
extends AbstractParallelAnyArray
    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.
