PublishedThe happy-collections is a library, which extends JDK java.collections, but also very well known collections from Google and Appache. org.happy collections is a set of decorators, which can be used for decorating existing Classes which implements the JDK-interfaces java.util.List, java.util.Collection, java.util.Set, java.util.Map.
Features:
Event based collections - register events like OnBeforeAddEvent or OnAfterRemoveEvent
Unmodifiable - you can decorate the collection, list, set, map by allowing for example only add new elements but nor removing any existing
SortedList - the decorator which decorates java.util.List to be sorted. There are two strategies implemented: (1) Linked and (2) Divide and Conquer. The Sorted List can increase the performance of the List dramatically (more than 20 times), see example section!
Cache - the decorator for java.util.Collection, java.util.List which caches often used elements and improves the performance of searching of elements in many cases.
