public class CayenneMap

extends org.apache.commons.collections.FastTreeMap

A CayenneMap is a specialized double-linked ordered map class. Attempts to add objects using an already existing keys will result in IllegalArgumentExceptions.

Normally CayenneMap is not subclassed directly, but is rather used as an instance variable within another class. Enclosing instance would set itself as a parent of this map.
