Class type Ext_data_proxy_Proxy.t

class type t = object .. end

method isProxy : bool Js.t Js.prop

true in this class to identify an object as an instantiated Proxy, or subclass thereof.

Defaults to: true

method isSynchronous : bool Js.t Js.prop

Identifies the proxy as (a)synchronous.

Defaults to: false

method batch : 'a. 'a Js.t -> Ext_data_Batch.t Js.t Js.meth

Performs a batch of Operations, in the order specified by batchOrder. Used internally by Ext.data.Store's sync method. Example usage:

myProxy.batch({
    create : [myModel1, myModel2],
    update : [myModel3],
    destroy: [myModel4, myModel5]
});

Where the myModel* above are Model instances - in this case 1 and 2 are new instances and have not been saved before, 3 has been saved previously but needs to be updated, and 4 and 5 have already been saved but should now be destroyed.

Note that the previous version of this method took 2 arguments (operations and listeners). While this is still supported for now, the current signature is now a single options argument that can contain both operations and listeners, in addition to other options. The multi-argument signature will likely be deprecated in a future release.

Parameters:

• options: _ Js.t

  Object containing one or more properties supported by the batch method:

Returns:

• Ext_data_Batch.t Js.t

  The newly created Batch

method destroy : 'd 'e. Ext_data_Operation.t Js.t -> 'd Js.callback -> 'e Js.t -> unit Js.meth

Performs the given destroy operation.
