Detailed Description
Bare clas to allow classes to be defined at run-time.
- A derived class of defineVI can check at run-time if it has been already defined or not. If not, it can execute the
define() method and define itself. - Lets consider the example of multialgorithms, that used other algorithms. At compile time maybe some algorithms are not beed defined yet. The class is therefore not defined at compile time. At run time, when the
initialize() (of algorithmVI) method is executed the first time, the derived class will them execute its define() method and define its algorithms. Setting the setDefine() to true, the define() method will not be executed again. - This class is useful to retreive at one, pointers that will keep their address constant during the live of the class.
