+</span> * @class Ext.util.MixedCollection
+ * <p>
+ * Represents a collection of a set of key and value pairs. Each key in the MixedCollection
+ * must be unique, the same key cannot exist twice. This collection is ordered, items in the
+ * collection can be accessed by index or via the key. Newly added items are added to
+ * the end of the collection. This class is similar to {@link Ext.util.HashMap} however it
+ * is heavier and provides more functionality. Sample usage:
+ * <pre><code>
+var coll = new Ext.util.MixedCollection();
+coll.add('key1', 'val1');
+coll.add('key2', 'val2');
+coll.add('key3', 'val3');
+
+console.log(coll.get('key1')); // prints 'val1'
+console.log(coll.indexOfKey('key3')); // prints 2
+ * </code></pre>
+ *
+ * <p>
+ * The MixedCollection also has support for sorting and filtering of the values in the collection.
+ * <pre><code>
+var coll = new Ext.util.MixedCollection();
+coll.add('key1', 100);
+coll.add('key2', -100);
+coll.add('key3', 17);
+coll.add('key4', 0);
+var biggerThanZero = coll.filterBy(function(value){
+ return value > 0;
+});
+console.log(biggerThanZero.getCount()); // prints 2
+ * </code></pre>
+ * </p>
