public final class Index

extends Object

Ranges provide the support to extract and operate on regular array sections. Indexes provide similar support for irregular sections. It is not possible to define an array section using Indexes, but one can use them in gather/scatter-like operations.

The only restriction is that elements in an Index must be nonnegative. The same value can appear multiple times in an Index. Indexes can be empty.
