The UIDUtil class is an all-static class with methods for working with UIDs (unique identifiers) within Flex. You do not create instances of UIDUtil; instead you simply call static methods such as the UIDUtil.createUID() method.

Note: If you have a dynamic object that has no [Bindable] properties (which force the object to implement the IUID interface), Flex adds an mx_internal_uid property that contains a UID to the object. To avoid having this field in your dynamic object, make it [Bindable], implement the IUID interface in the object class, or set a property with a value.
