Back to FileSystem Class Summary

Availability
Windows, Mac OSX, Linux

Usage
mdm.FileSystem.getFileListAsync(folderPath:String, searchMask:String):void

Parameters
folderPath:String - Path to a folder
searchMask:String - Search mask

Returns
Nothing

Description
This method asynchronously returns a list of files that exist in the specified folder with optional search mask to match only specified filenames. When operation completes either "onResult" or "onIOError" events are delivered to registered listeners (or assigned callbacks: see notes below).
The "onResult" event would have an array of results:
var matchedFiles:Array = event.data.result as Array;

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.onResult = function(event:mdm.Event):void
{
// operation completed/finished
var files:Array = event.data.result as Array};
};
mdm.FileSystem.onIOError = function(event:Event):void
{
// operation failed
};
mdm.FileSystem.getFilesListAsync(path, searchMask);

// event-listener implementation
function onResultHandler(event:mdm.Event):void
{
// operation completed/finished
var files:Array = event.data.result as Array;
};
function onIOErrorHandler(event:Event):void
{
// operation failed
};
mdm.FileSystem.addEventListener("onResult", onResultHandler);
mdm.FileSystem.addEventListener("onIOError", onIOErrorHandler);
mdm.FileSystem.getFilesListAsync(path, searchMask);
