Joda-Collect

About

Joda-Collect provides collections that are not present in the JDK or Google Guava.

The JDK and Guava contain many collection classes, but occasionally there is something missing. This project provides a home for those collections.

Joda-Collect is licensed under the business-friendly Apache 2.0 licence.

Features

Included collection types:

Grid - A grid data structure, providing access to its values by row and column. This is similar to Guava’s Table, but uses int for the row and column, allowing optimisations. Mutable and immutable implementations are provided in sparse and dense variations.

Documentation

Various documentation is available:

The Javadoc
The change notes for each release
