hashed data. Defaults to true. When using
Ext.data.DirectProxy, set this to false since Ext.Direct.JsonProvider will perform
its own json-encoding. In addition, if you're using Ext.data.HttpProxy, setting to false
will cause HttpProxy to transmit data using the jsonData configuration-params of Ext.Ajax.request
instead of params. When using a Ext.data.Store.restful Store, some serverside frameworks are
tuned to expect data through the jsonData mechanism. In those cases, one will want to set encode: false, as in
let the lower-level connection object (eg: Ext.Ajax) do the encoding. | JsonWriter | |

even when acting upon a single record. | DataWriter | |

apply( Object params , Object baseParams , String action , Record/Record[] rs )
:
voidCompiles a Store recordset into a data-format defined by an extension such as Ext.data.JsonWriter or Ext.data.XmlWrit... Compiles a Store recordset into a data-format defined by an extension such as Ext.data.JsonWriter or Ext.data.XmlWriter in preparation for a server-write action. The first two params are similar similar in nature to Ext.apply,
Where the first parameter is the receiver of paramaters and the second, baseParams, the source. Parameters:

eg, non-phantom:
Phantom records will have had their idProperty omitted in toHash if determined to be auto-generated.
Non AUTOINCREMENT pks should have been protected.Parameters:
