GS Collections is a collections framework for Java. It has JDK-compatible List, Set and Map implementations with a rich API and set of utility classes that work with any JDK compatible Collections, Arrays, Maps or Strings. The iteration protocol was inspired by the Smalltalk collection framework.

There is a newer version: 7.0.3

/**
 * IntIterable is an interface which is memory-optimized for int primitives.
 * It is inspired by the interface RichIterable, and contains a subset of the internal iterator methods on RichIterable like collect, sum, etc.
 * The API also includes an external iterator method, which returns an IntIterator. IntIterator helps iterate over the IntIterable without boxing the primitives.
 * This file was automatically generated from template file primitiveIterable.stg.
