ListBase

The UIDUtil class is a utility class for manipulating UIDs (universal identifiers) in Flex. A UID is a very unique String which is hopefully fully unique. The UID is intended to be a unique index to a particular instance of a class in Flex. The UIDUtil class has static methods that can create and fetch UIDs for any Object in a Flash application. UIDUtil is commonly used by the list classes to index their contents and provide lookups for various purposes.

The ListBase class is the base class for all of the list classes in Flex which are:

• List
• Tree
• Menu
• DataGrid
• TileList

List classes share a common interface through the dataProvider properties and they dispatch similar events.
