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.

| AttributeCore(attrs, values, lazy) X-Ref |
| <p> AttributeCore provides the lightest level of configurable attribute support. It is designed to be augmented on to a host class, and provides the host with the ability to configure attributes to store and retrieve state, <strong>but without support for attribute change events</strong>. </p> <p>For example, attributes added to the host can be configured:</p> <ul> <li>As read only.</li> <li>As write once.</li> <li>With a setter function, which can be used to manipulate values passed to Attribute's <a href="#method_set">set</a> method, before they are stored.</li> <li>With a getter function, which can be used to manipulate stored values, before they are returned by Attribute's <a href="#method_get">get</a> method.</li> <li>With a validator function, to validate values before they are stored.</li> </ul> <p>See the <a href="#method_addAttr">addAttr</a> method, for the complete set of configuration options available for attributes.</p> <p>Object/Classes based on AttributeCore can augment <a href="AttributeObservable.html">AttributeObservable</a> (with true for overwrite) and <a href="AttributeExtras.html">AttributeExtras</a> to add attribute event and additional, less commonly used attribute methods, such as `modifyAttr`, `removeAttr` and `reset`.</p> param: attrs {Object} The attributes to add during construction (passed through to <a href="#method_addAttrs">addAttrs</a>). param: values {Object} The initial attribute values to apply (passed through to <a href="#method_addAttrs">addAttrs</a>). param: lazy {boolean} Whether or not to add attributes lazily (passed through to <a href="#method_addAttrs">addAttrs</a>). |
