Overview

Libgee is an utility library providing GObject-based interfaces and classes for commonly used data structures.

Libgee provides the following interfaces:

  • Travsersable
  • Iterable
  • Collection
  • List
  • BidirList
  • Set
  • SortedSet
  • BidirSortedSet
  • MultiSet
  • Queue
  • Deque
  • Map
  • SortedMap
  • BidirSortedMap
  • Iterator
  • BidirIterator
  • BidirListIterator
  • ListIterator
  • BidirListIterator
  • MultiMap
  • Future

The ArrayList, ArrayQueue ConcurrentLinkedList, ConcurrentSet, HashSet, HashMap, HashMultiSet, HashMultiMap, LinkedList, PriorityQueue, Promise, TreeSet, TreeMap, TreeMultiSet, and TreeMultiMap classes provide a reasonable sample implementation of those interfaces. In addition, a set of abstract classes are provided to ease the implementation of new collections.

Around that, the API provide means to retrieve read-only views, efficient sort algorithms, simple, bi-directional or index-based mutable iterators depending on the collection type.

Libgee is written in Vala and can be used like any GObject-based C library. It's planned to provide bindings for further languages.
