Klojang Collections

A small collection of classes extending the Java Collections framework.

TypeMap — an extension of the Map interface which maps Java types of values. Its get() and containsKey() methods leverage the structure of the Java type hierarchy to find a value for the requested key. If the requested key (a Class object) is not itself present in the map, but one of its supertypes is, then the value associated with the supertype is returned - or true in the case of containsKey(). The Klojang Collections module provides four implementations, each with different performance characteristics and key ordering.
TypeSet — the Set counterpart to the TypeMap interface. Its contains() method behaves just like the containsKey() method of TypeMap.
WiredList and CrisprList — doubly-linked lists much like the JDK’s own LinkedList but exclusively focused on destructive edits like moving around (large) list segments - the one thing that doubly-linked list can potentially execute much more efficiently ArrayList.
