The component library is a collection of components that can be used to create complex projects quickly and reliably. The component library simplifies development by eliminating the need to re-implement existing functionality. This contributes to shorter development cycles as well as smaller code bases, helping reduce the number of bugs by leveraging tried and tested code. The component library also provides the same interface in multiple environments, such as kernel mode and user mode, allowing code to be used in both, again reducing code duplication and development life cycles. Components of the library all follow the same usage model, as follows: - The constructor for all components should be called before any other function for that component. It is acceptable to call the initializer without first calling the constructor. - The initializer for all components must be called successfully before any function manipulating that component is called. - The destructor for all components must be called if the initializer was called. In a debug build, the components assert that the proper sequence is followed.
