Bin2DataStreamer

Overview

Bin2DataStreamer implementation compatible with other platforms. Some 64bit data types that hold big values are limited to 48bit due to nature of JavaScript numbers. Shouldn't be created directly by user, just provide streamer class when creating data adapter.

var channel = new RemObjects.SDK.HTTPClientChannel("http://" + window.location.host + "/JSON");
var message = new RemObjects.SDK.JSONMessage();
var service = new RemObjects.SDK.RemoteService(channel, message, "DASampleService");
var loginService = new RemObjects.SDK.RemoteService(channel, message, "LoginService");
var rda = new RemObjects.DataAbstract.RemoteDataAdapter(service, loginService, RemObjects.DataAbstract.Bin2DataStreamer);
