Class Ext.data.Writer

Package:	Ext.data
Defined In:	Writer.js
Class:	Writer
Subclasses:	JsonWriter, XmlWriter
Extends:	Object

Base Writer class used by most subclasses of Ext.data.ServerProxy. This class is responsible for taking a set of Ext.data.Operation objects and a Ext.data.Request object and modifying that request based on the Operations.

For example a Ext.data.JsonWriter would format the Operations and their Ext.data.Model instances based on the config options passed to the JsonWriter's constructor.

Writers are not needed for any kind of local storage - whether via a Web Storage proxy (see localStorage and sessionStorage) or just in memory via a MemoryProxy.
