State Class

Defined in: attribute/js/State.js:1
Module: attribute

The State class maintains state for a collection of named items, with a varying number of properties defined.

It avoids the need to create a separate class for the item, and separate instances of these classes for each item, by storing the state in a 2 level hash table, improving performance when the number of items is likely to be large.
