Package	mx.utils
Class	public class DescribeTypeCache
Inheritance	DescribeTypeCache Object

DescribeTypeCache is a convenience class that is used to cache the return values of flash.utils.describeType() so that calls made subsequent times return faster. This class also lets you set handler functions for specific value types. These will get called when the user tries to access these values on the DescribeTypeCacheRecord class.
