Library providing general-purpose mutable lists, sets, and maps. The following interfaces define abstract mutable collection types: - [[MutableList]] is a mutable [[List]], - [[MutableSet]] is a mutable [[Set]], and - [[MutableMap]] is a mutable [[Map]]. These interfaces define abstract sorted collection types: - [[SortedSet]] is a sorted [[Set]], and - [[SortedMap]] is a sorted [[Map]]. In addition, dedicated [[Stack]] and [[Queue]] interfaces are defined, representing specialized kinds ...
