Detailed Description
Communication channel between the C++ QWebChannel server and a HTML/JS client.
Users of the QWebChannel must implement this interface and connect instances of it to the QWebChannel server for every client that should be connected to the QWebChannel. The {Qt WebChannel Standalone Example}{Standalone Example} shows how this can be done using Qt WebSockets. Qt WebKit implements this interface internally and uses the native WebKit IPC mechanism to transmit messages to HTML clients.
Note: The JSON message protocol is considered internal and might change over time.
See also Qt WebChannel Standalone Example.

Constructs a transport object with the given parent.
[virtual] QWebChannelAbstractTransport::~QWebChannelAbstractTransport()
Destroys the transport object.
[signal] void QWebChannelAbstractTransport::messageReceived(const QJsonObject & message, QWebChannelAbstractTransport * transport)
This signal must be emitted when a new JSON message was received from the remote client. The transport argument should be set to this transport object.
[pure virtual slot] void QWebChannelAbstractTransport::sendMessage(const QJsonObject & message)
Send a JSON message to the remote client. An implementation would serialize the message and transmit it to the remote JavaScript client.
