Data binding is one of the most used processes when building Flex applications because it allows rapid development of Flex applications. Data binding allows you to pass data between different layers of the application automatically and makes development of Flex applications easy, fast, and enjoyable. Although Data binding contains tremendous value, it also holds some disadvantages for the unwary: without understanding exactly how data binding works and ensuring it is being used correctly and when needed, data binding can create bottlenecks, overheads, and memory leaks, which will cause your application to suffer in term of performance. Although you may not notice these performance differences when building a small Flex application, as your application scales up you may start seeing performance issues and data binding may be responsible for some of these issues, so it is better to build your application correctly from the start and avoid potential issues. If you have developed Flex applications in the past, I am sure you have already used data binding, so the intention of this chapter is to provide you with basic and advanced techniques to use data binding so you know what s possible, as well as explain in detail what s going on under the hood so you will know how to use data binding correctly without causing any overhead or memory leaks. We are confident that a better understanding of how data binding works, and knowing all the different options that are available to you, while using data binding can help you build a better Flex application and avoid bottlenecks that can be caused by misuse of data binding.

To apply this idea and create the maze, the first step is to use the screen and graphics dimensions to determine the size of your grid of vertices (how many squares across and how many down) In this implementation, I start by dividing the entire playing field into equal-sized squares, which form part of the maze pathways if colored white and part of the maze wall if colored black There s a lattice of squares that I know should be black and a lattice that I know should be white, and the trick is to figure out which colors to give to the wildcard squares In Figure 2-8, I ve colored gray all of the squares whose color should be decided by the algorithm (note that this screen never appears in the final game).

The Data binding process enables the tying of one object s data with another object. The concept of data binding is that by connecting a source object with a destination object, once the source object changes then the destination object also changes automatically. Additionally, Flex 4 offers two-way data binding, also known as bi-directional data binding, which enables two objects to be tied to each other allowing data to be changed when either object changes.

The data member was not added for triviality, but has a specific purpose and is a version number for the latest state Whenever an HTTP POST is executed, the call counter is incremented, meaning that the state has been updated Using the call counter as a reference, a server can indicate whether new content is available The server cannot know when to send a message to the client without getting a helping hand from the client, because the server does not know which state the client has already received The client needs to implement a change, whereby the client notes the version number and stores the value somewhere on the client temporarily Then when the next request is made, the value is sent to the server and that value helps the server decide whether the client should wait for new data or be immediately sent the latest data.

There are five main techniques for using Data Binding, which we will be covering in this chapter:

Using braces with MXML tags Using the fx:Binding tag Using the BindingUtils class Implicit and explicit data binding Custom metadata

In graph terms, the white squares are the vertices, and the gray squares are the squares that might potentially be edges by being added to the maze pathway and turned white You can see from this that the number of rows and number of columns both need to be odd numbers That s why every time the grid size is.

Braces are the most commonly used technique to employ data binding in Flex applications. They allow you to bind properties without writing any actual code other than placing the braces. You set the braces, and once the application is compiled the compiler generates the code that does the binding automatically for you. Up until Flex 4, you could do a one-way data binding. In Flex 4, you can also do a two-way data binding.
