This document is the API Specification for Flash Client 1.2.

Summary

This SDK contains two libraries: one for JavaScript (lsflashbridge.js) and one for ActionScript (lsjavascriptbridge.as). Such two libraries directly communicate in order to inject any real-time events received from Lightstreamer Server (through the Lightstreamer HTML Client) into a Flash application.
In order to achieve this:

• Include flash.external.ExternalInterface and lsjavascriptbridge.as in each Flash movie where pushed data have to be displayed. Note that the .as file uses ExternalInterface.addCallback to expose through JavaScript some methods. This means you should not expose methods with the same names:
  • onReady
  • onStatusChange
  • onLostUpdates
  • onEndOfSnapshot
  • onItemUpdate
  • onStart
• Create and configure a JavaScriptBridge object and add a "Table" object for each data table to be requested. You must give to the JavaScriptBridge object a name. This name will be also used in the HTML page and in the JavaScript code.
• Include lsflashbridge.js (lscommons.js and lspushpage.js see below) in each page where a Flash movie that needs pushed data has to be embedded. Then create and configure a FlashBridge object with the same name previously given to the JavaScriptBridge object.
• Make each page where a Flash movie is being embedded a "Push- page" using the HTML Client SDK.
• Embed your Flash movie in the Push- page. Use the name given to JavaScriptBridge and FlashBridge as the "id" of the object tag and as the "name" of the embed tag.
