Joda-Collect provides collections that are not present in the JDK or Google Guava.
The project is related to Joda-Primitives which provides primitive versions of the collection interfaces. This project is separate, as the use cases are likely to be different.
Joda-Collect is licensed under the business-friendly Apache 2.0 licence.
Joda-Collect contains the following collections:
- Grid - a grid data structure, providing access to its values by row and column.
This is similar to Guava's
Table, but usesintfor the row and column, allowing optimisations. Mutable and immutable implementations are provided in sparse and dense variations.
Various documentation is available:
The 2.x branch is compatible with Java SE 21 or later.
The 1.x branch is compatible with Java SE 8 or later.
v2.x releases are compatible with v1.x releases - except for the Java SE version and module-info.class file.
Guava is a required module, but it cannot be declared as 'transitive' because it is an automatic module.
Joda-Collect depends on Google-Guava.
