This class is an abstract base class for implementations which provide retrieval of
|
|
unformatted data objects.
|
|
<p>
|
|
DataProxy implementations are usually used in conjunction with an implementation of Ext.data.DataReader
|
|
(of the approriate type which knows how to parse the data object) to provide a block of Records
|
|
to an Ext.data.Store.
|
|
<p>

Custom implementations must implement the load method as described in
