/**
* @class Ext.CompositeElementLite
- * Flyweight composite class. Reuses the same Ext.Element for element operations.
-
- var els = Ext.select("#some-el div.some-class");
- // or select directly from an existing element
- var el = Ext.get('some-el');
- el.select('div.some-class');
+ *
This class encapsulates a collection of DOM elements, providing methods to filter
+ * members, or to perform collective actions upon the whole set.
+ *
Although they are not listed, this class supports all of the methods of {@link Ext.Element} and
+ * {@link Ext.Fx}. The methods from these classes will be performed on all the elements in this collection.
+ * Example:
+var els = Ext.select("#some-el div.some-class");
+// or select directly from an existing element
+var el = Ext.get('some-el');
+el.select('div.some-class');
- els.setWidth(100); // all elements become 100 width
- els.hide(true); // all elements fade out and hide
- // or
- els.setWidth(100).hide(true);
-
- * NOTE: Although they are not listed, this class supports all of the set/update methods of Ext.Element. All Ext.Element
- * actions will be performed on all the elements in this collection.
+els.setWidth(100); // all elements become 100 width
+els.hide(true); // all elements fade out and hide
+// or
+els.setWidth(100).hide(true);
