Defined In: | DataProxy.js |
Class: | DataProxy |

This class is an abstract base class for implementations which provide retrieval of
unformatted data objects.
DataProxy implementations are usually used in conjunction with an implementation of Ext.data.DataReader
(of the appropriate type which knows how to parse the data object) to provide a block of
Ext.data.Records to an Ext.data.Store.
Custom implementations must implement the load method as described in
Ext.data.HttpProxy.load.
