Event
|
A base class for all Ext.direct events. An event is
created after some kind of interaction with the server.
The event class is essentially just a data structure
to hold a direct response.

Overview Ext.Direct aims to streamline communication between the client and server
by providing a single interface that reduces the amount of common code
typically required to validate data and handle returned data packets
(reading data, error conditions, etc). The Ext.direct namespace includes several classes for a closer integration
with the server-side. The Ext.data namespace also includes classes for working
with Ext.data.Stores which are backed by data from an Ext.Direct method. Specification For additional information consult the
Ext.Direct Specification. Providers Ext.Direct uses a provider architecture, where one or more providers are
used to transport data to and from the server. There are several providers
that exist in the core at the moment: JsonProvider for simple JSON operations PollingProvider for repeated requests RemotingProvider exposes server side
on the client. A provider does not need to be invoked directly, providers are added via
Ext.direct.Manager.addProvider. Router Ext.Direct utilizes a "router" on the server to direct requests from the client
to the appropriate server-side method. Because the Ext.Direct API is completely
platform-agnostic, you could completely swap out a Java based server solution
and replace it with one that uses C# without changing the client side JavaScript
at all. Server side events Custom events from the server may be handled by the client by adding
listeners, for example: {"type":"event","name":"message","data":"Successfully polled at: 11:19:30 am"}
// add a handler for a 'message' event sent by the server
Ext.direct.Manager.on('message', function(e){
out.append(String.format('<p><i>{0}</i></p>', e.data));
out.el.scrollTo('t', 100000, true);
});

PollingProvider
|
Provides for repetitive polling of the server at distinct intervals.
The initial request for data originates from the client, and then is responded to by the
server. All configurations for the PollingProvider should be generated by the server-side
API portion of the Ext.Direct stack. An instance of PollingProvider may be created directly via the new keyword or by simply
specifying type = 'polling'. For example: var pollA = new Ext.direct.PollingProvider({
type:'polling',
url: 'php/pollA.php',
});
Ext.direct.Manager.addProvider(pollA);
pollA.disconnect();
Ext.direct.Manager.addProvider(
{
type:'polling',
url: 'php/pollB.php',
id: 'pollB-provider'
}
);
var pollB = Ext.direct.Manager.getProvider('pollB-provider');

Ext.direct.RemotingProvider. Contains a method to the
related transaction for the direct request, see getTransaction

RemotingProvider
|
The RemotingProvider exposes access to
server side methods on the client (a remote procedure call (RPC) type of
connection where the client can initiate a procedure on the server). This allows for code to be organized in a fashion that is maintainable,
while providing a clear path between client and server, something that is
not always apparent when using URLs. To accomplish this the server-side needs to describe what classes and methods
are available on the client-side. This configuration will typically be
outputted by the server-side Ext.Direct stack when the API description is built.
