Security
The StoreAPI object calls the main application to retrieve the regular album price, but returns “Not available” when
the getSaleAlbumPrice() method is called. The following code defines the StoreAPI class:
public class StoreAPI
{
private static var musicStore:Object;
}
public function StoreAPI(musicStore:Object)
{
this.musicStore = musicStore;
}
public function getRegularAlbumPrice():String {
return musicStore.getRegularAlbumPrice();
}
public function getSaleAlbumPrice():String {
return "Not available";
}
public function getAlbumPrice():String {
return musicStore.getRegularAlbumPrice();
}
The following code represents an example of a PriceQuoter SWF file that reports the store’s price, but cannot report
the sale price:
package
{
import flash.display.Sprite;
import flash.system.Security;
import flash.text.*;
}
public class PriceQuoter extends Sprite
{
private var storeRequester:Object;
}
public function PriceQuoter() {
trace("Initializing child SWF");
trace("Child sandbox: " + Security.sandboxType);
storeRequester = loaderInfo.parentSandboxBridge;
}
var tf:TextField = new TextField();
tf.autoSize = TextFieldAutoSize.LEFT;
addChild(tf);
tf.appendText("Store price of album is: " + storeRequester.getAlbumPrice());
tf.appendText("\n");
tf.appendText("Sale price of album is: " + storeRequester.getSaleAlbumPrice());
