Hi! I'm trying to create a simple 'file database' in AIR.
I know I can save and restore objects in AMF format using the methods
write/restoreObject.
here is my code to save:
var DocumentToSave:DocumentFile = new DocumentFile(); //DocumentFile
is a custom class
DocumentToSave.Name = 'some name';
var file:File = File.applicationStorageDirectory.resolvePath
('myApp.data');
var stream:FileStream = new FileStream();
stream.open(file, FileMode.APPEND);
stream.writeObject(DocumentToSave);
That code is working and stores the DocumentFile objects and values.
But, what can I do to retrieve that objects (or any particular
object).
I tried this to retrieve:
var file:File = File.applicationStorageDirectory.resolvePath
('myApp.data');
var stream:FileStream = new FileStream();
stream.open(file, FileMode.READ);
var arr:Array = new Array();
while(stream.bytesAvailable){
//what can I use here to create an array of DocumentFiles stored
in 'myApp.data'?
arr = stream.readObject() as Array; //seems to work
}
trace('new arr length: ' + arr.length);//doesn't work, why??
Any help?
Thanks in advance!
