Back to FileSystem Class Summary

Availability
Windows, Mac OSX, Linux

Usage
mdm.FileSystem.appendFileAsync(filePath:String, dataToAdd:String):void

Parameters
filePath:String - Path to file where data will be appended
dataToAdd:String - Data to be added to file

Returns
Nothing

Description
Appends the specified text data to the specified file. This is asynchronous method: once operation finishes it will dispatch either "onComplete" or "onIOError" events to registered listeners (or callback via assigned handlers: see notes below).

Notes
There are two ways to listen for events in 4.0:
#1
using "onEventNameFunction" - callback based handlers introduced in {mdm} 2.0
#2
using IEventListener model based on Events introduced in 4.0.

No matter what implementation you would use either callback and listener handler would have to use single-argument defintion as in below sample:
// callback based handlers
mdm.Appllication.onAppChangeFocus = function(event:Event):void
{
// proceed with event
};

// handlers based on IEventListener model
function onAppChangeFocusHandler(event:Event):void
{
// proceed with event
};

Example Code
// callback version
mdm.FileSystem.onComplete = function(event:Event):void
{
// operation completed/finished
};
mdm.FileSystem.onIOError = function(event:Event):void
{
// operation failed
};
mdm.FileSystem.appendFileAsync(path, data);

// event-listener implementation
function onCompleteHandler(event:Event):void
{
// operation completed/finished
};
function onIOErrorHandler(event:Event):void
{
// operation failed
};
mdm.FileSystem.addEventListener("onComplete", onCompleteHandler);
mdm.FileSystem.addEventListener("onIOError", onIOErrorHandler);
mdm.FileSystem.appendFileAsync(path, data);
