atg.core.util.ArrayDictionary

public class ArrayDictionary
extends java.util.Dictionary

An ArrayDictionary is an implementation of Dictionary that stores its keys and values as arrays. Lookups are performed using a linear search. Adding new elements requires no new object allocations. This is best used for very small key/value mappings that require a Dictionary interface. In addition, this allows null values to be exposed as values, if the ArrayDictionary is created with a pair of arrays. Other Dictionary implementations, such as Hashtable, do not allow null values.
