mysql-live-client/compiled/lib/Handler.js

The client side script of mysql-live package.

/* Handler deals with socket, Receiver and Dispatcher. */
/* Receiver Accepts from server and do client side actions. */
/* Dispatcher Accepts from client, and push to the server.*/
/* The Handler is a middleware between receiver and dispatcher. */
/* Both Receiver and Dispatcher will have reference to the Handler class because:
   The Handler is the only one class will have the socket reference (socket.on,socket.emit).*/
/* Handler is also the only class which keep the collections dictionary, just that, nothing here to do with collections. */
/* Handler initializes the Receiver, and the Dispatcher. */
/* Handler is initialized by the MysqlLiveClient. */
/* The only difference from the server-side style code is that the Collection here,
   should make emits/send actions to the server, so we pass the Dispatcher to the Collection Object as an argument on constructor.*/
