I am addaptnig some code I got from the Internet. It does what I want, but I need some help to fullly understand how it works. Here it is.
// My main application file:
.....
<logging:GlobalExceptionHandler preventDefault="true" >
<logging:LogHandlerAction/>
</logging:GlobalExceptionHandler>
package
{
import flash.display.LoaderInfo;
import flash.events.UncaughtErrorEvent;
import mx.managers.ISystemManager;
[Mixin]
[DefaultProperty("handlerActions")]
public class GlobalExceptionHandler
{
private static var loaderInfo:LoaderInfo;
public var handlerActions:Array;
public var preventDefault:Boolean = false;
public static function init(sm:ISystemManager):void
{
loaderInfo = sm.loaderInfo;
}
public function GlobalExceptionHandler()
{
loaderInfo.uncaughtErrorEvents.addEventListener(UncaughtErrorEvent.UN CAUGHT_ERROR,
uncaughtErrorHandler);
}
private function uncaughtErrorHandler(event:UncaughtErrorEvent):void
{
for each (var action:GlobalExceptionHandlerAction in handlerActions)
{
action.handle(event.error);
}
if (preventDefault == true)
{
event.preventDefault();
}
}
}
}
package
{
public interface GlobalExceptionHandlerAction
{
function handle(error:Object):void;
}
}
package stoneriver.util.logging
{
import stoneriver.util.logging.ErrorLogger;
public class LogHandlerAction implements GlobalExceptionHandlerAction
{
private var _log:ErrorLogger = ErrorLogger.getInstance();
public function handle(error:Object):void
{
if (error is Error)
{
var errorObj:Error = error as Error;
// This will start logging errors
_log.error(errorObj);
}
}
}
}
Basically my question is:
How does handlerActions array get its elements?
Thanks
