Class ParallelDoubleArrayWithLongMapping

java.lang.Object
extra166y.AbstractParallelAnyArray
extra166y.ParallelDoubleArrayWithLongMapping

public abstract class ParallelDoubleArrayWithLongMapping extends AbstractParallelAnyArray
A prefix view of ParallelDoubleArray 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.
