Adobe AIR read and write file System – Part2

AIR Tutorials, Getting Started No Comments »

In my last tutorial Part1 I discussed on basics of  file classes File, FileMode & FileStream and also showed an example on how to point the file object to the desktop and list all the files and directories available under desktop and display the same inside the list component.

In this tutorial shall try to show on how to use FileMode.READ & FileMode.WRITEand also discuss on Asynchronous and Synchronous methods.

FileStream class has both synchronous and asynchronous

In synchronous method you cannot invoke other actions at a same time. Imagine if you are loading a huge file using synchronous method you need to wait until the file is loaded to process other actions.

Whereas in asynchronous method, these methods can run in a background allowing other actions to run at the same time and when an asynchronous actions completes it can dispatch events to the listeners on the status like if the files is loaded or if the file is read etc.

After hitting the market with its first version in February 2008, ADOBE AIR has come a long way and is simply becoming the first choice of more than 100 million users across the globe.

AIR started its journey with the name “Apollo” in March, 2007. After being renamed its first public beta version was released in June, 2007. The second and the third versions soon followed in the months of October and December.

This cross-platform Runtime environment is better equipped with the latest versions of Flash, Flex, HTML and AJAX and has made the user-experience more pleasant.

Now, managing huge database files is not a problem. AIR provides the leverage of storing all SQL data tables on your local machine and even protecting them using a 128-bit AES-CCM key encryption.

It successfully passed the cycling encryption-key test which is aimed at randomizing the passwords and maintaining a single user session under protected environment of a secure-cookie. XML parsers have always made the validation easy and universal in nature. With the addition of this feature, AIR has become a complete package. It also comes with important tools for security perspective to substantiate against signer revocation lists.
