/**
|
||||
* @fileoverview The API spec for the WebChannel messaging library.
|
||||
*
|
||||
* Similar to HTML5 WebSocket and Closure BrowserChannel, WebChannel
|
||||
* offers an abstraction for point-to-point socket-like communication between
|
||||
* a browser client and a remote origin.
|
||||
*
|
||||
* WebChannels are created via <code>WebChannel</code>. Multiple WebChannels
|
||||
* may be multiplexed over the same WebChannelTransport, which represents
|
||||
* the underlying physical connectivity over standard wire protocols
|
||||
* such as HTTP and SPDY.
|
||||
*
|
||||
* A WebChannels in turn represents a logical communication channel between
|
||||
* the client and server end point. A WebChannel remains open for
|
||||
* as long as the client or server end-point allows.
|
||||
*
|
||||
* Messages may be delivered in-order or out-of-order, reliably or unreliably
|
||||
* over the same WebChannel. Message delivery guarantees of a WebChannel is
|
||||
* to be specified by the application code; and the choice of the
|
||||
* underlying wire protocols is completely transparent to the API users.
|
||||
*
|
||||
* Client-to-client messaging via WebRTC based transport may also be support
|
||||
* via the same WebChannel API in future.
|
||||
*
|
||||
* Note that we have no immediate plan to move this API out of labs. While
|
||||
* the implementation is production ready, the API is subject to change
|
||||
* (addition):
|
||||
* 1. Completely new W3C APIs for Web messaging may emerge in near future.
|
||||
* 2. New programming models for cloud (on the server-side) may require
|
||||
* new APIs to be defined.
|
||||
* 3. WebRTC DataChannel alignment
|
||||
* Lastly, we also want to white-list all internal use cases. As a general rule,
|
||||
* we expect most applications to rely on stateless/RPC services.
