- * @class Ext.tree.TreeSorter
- * Provides sorting of nodes in a {@link Ext.tree.TreePanel}.  The TreeSorter automatically monitors events on the
- * associated TreePanel that might affect the tree's sort order (beforechildrenrendered, append, insert and textchange).
- * Example usage:<br />
- * <pre><code>
-new Ext.tree.TreeSorter(myTree, {
-    folderSort: true,
-    dir: "desc",
-    sortType: function(node) {
-        // sort by a custom, typed attribute:
-        return parseInt(node.id, 10);
-    }
-});
-</code></pre>
- * @constructor
- * @param {TreePanel} tree
- * @param {Object} config
- */
-Ext.tree.TreeSorter = function(tree, config){
-    /**
-     * @cfg {Boolean} folderSort True to sort leaf nodes under non-leaf nodes (defaults to false)
-     */
-    /**
-     * @cfg {String} property The named attribute on the node to sort by (defaults to "text").  Note that this
-     * property is only used if no {@link #sortType} function is specified, otherwise it is ignored.
-     */
-    /**
-     * @cfg {String} dir The direction to sort ("asc" or "desc," case-insensitive, defaults to "asc")
-     */
-    /**
-     * @cfg {String} leafAttr The attribute used to determine leaf nodes when {@link #folderSort} = true (defaults to "leaf")
-     */
-    /**
-     * @cfg {Boolean} caseSensitive true for case-sensitive sort (defaults to false)
-     */
-    /**
-     * @cfg {Function} sortType A custom "casting" function used to convert node values before sorting.  The function
-     * will be called with a single parameter (the {@link Ext.tree.TreeNode} being evaluated) and is expected to return
-     * the node's sort value cast to the specific data type required for sorting.  This could be used, for example, when
-     * a node's text (or other attribute) should be sorted as a date or numeric value.  See the class description for
-     * example usage.  Note that if a sortType is specified, any {@link #property} config will be ignored.
