This Class gives you ability to download and upload files via FTP connection and get directory list from specified path. Best thing is that you can use its smart behavior to perform multiple tasks in the queue (for example, this way you can easly upload multiple files).

How to use paths:
localPath example - "C:/test1.txt"
ftpPath example - "/public_html/test2.txt"

Methods

SmartFTP(host:String = null, username:String = null, password:String = null, port:int = 21):void
Constructor which gives you ability to make connection immediately

upload(localPath:String, ftpPath:String = ''):void
Upload file from "localPath" to "ftpPath". This method won't work if there is no connection or socket is busy

uploadTask(localPath:String, ftpPath:String = ''):void
Create new upload task. Tasks are triggered soon as possible (when connection is active and non busy) one after another

download(localPath:String, ftpPath:String):void
Download file from "ftpPath" to "localPath". This method won't work if there is no connection or socket is busy

downloadTask(localPath:String, ftpPath:String):void
Create new download task. Tasks are triggered soon as possible (when connection is active and non busy) one after another

dirListMsg(ftpPath:String):void
Read directory list from "ftpPath". You can get result (directory list message) from "msg" property from event listener or stored message list

dirListMsgTask(ftpPath:String):void
Create new "read directory list" task. Tasks are triggered soon as possible (when connection is active and non busy) one after another

open(host:String = null, username:String = null, password:String = null, port:int = 21):void
Opens connection

close():void
Closes connection

closeTask():void
Closes connection task. Tasks are triggered soon as possible (when connection is active and non busy) one after another

closeStream():void
Closes any read/write stream for upload or download. Be aware that it's not recomended to use it because it will not stop processes accompanying to upload/download. For safety it's better to use method "close()" or "closeData()"

closeData(closeDataTasks:Boolean = true):void
Closes everything expect connection and tasks if "closeDataTasks" is set to "false"

clearMessage():void
Clears all stored messages

clearError():void
Clears all stored error messages

Properties

listener:Function
This function will be used to detect events. Function passes object with few properties: target (current SmartFTP instance), code (response code number), type (event type), task (name of task - source of event), msg (last original message received from server)

message:String
Read only. Returns all messages as one string

messageVec:Vector.<String>
Read only. Returns all messages as vector array

error:String
Read only. Returns all errors as one string

errorVec:Vector.<String>
Read only. Returns all errors as vector array

taskList:Vector.<Object>
Read only. Returns original task list

fileData:ByteArray
Read only. Returns last used ByteArray data

connected:Boolean
Read only. Returns true if connection is active

connectedData:Boolean
Read only. Returns true if socked for transfer data is active

busy:Boolean
Read only. Return true if connection is busy (new action can not be taken until connection is busy)

host:String
Read only. Returns current host

username:String
Read only. Returns current user name

host:String
Read only. Returns current host

password:String
Read only. Returns current password

port:int
Read only. Returns current port

path:String
Read only. Returns current task name

Event Types

To be able to recognize events you need to use event type names. It could be problematic to remember all those types, and that's why it's better to use static variables which holds them.

List of variables (event types):   LOGIN_SUCCESS,   DOWNLOAD_SUCCESS,   UPLOAD_SUCCESS,   CONNECTION_CLOSED,   CONNECTION_TIMEOUT,   LOGIN_FAILD,   DIRECTORY_FAILD,   UPLOAD_STREAM_SUCCESS,   STREAM_CLOSED,   ERROR,   DIR_LIST_RECEIVED

	  var mySmartFTP = new SmartFTP();
	  mySmartFTP.listener = myListenerFunction;

	  function myListenerFunction(e):void {//e:Object
	     if (e.type == SmartFTP.LOGIN_SUCCESS) {
	        trace('You are logged in!');
	     }
	  }
