XPRSprob.AbstractUserFunction Class

Base class for user functions. You will usually not have to create an instance of this class or its subclasses yourself. Instead the way to create an instance is to use an XPRSprob instance as factory:
C# 
MapFunction f = prob.NlpAddUserFunction("myf", 0, d -> 2 * d);
That is, you create an instance of XPRSprobMapFunctor, XPRSprobVecMapFunctor, XPRSprobMultiMapFunctor, XPRSprobMapDeltaFunctor, XPRSprobVecMapDeltaFunctor, or XPRSprobMultiMapDeltaFunctor and then pass that to the appropriate overload of nlpAddUserFunction. This will register the function with the Xpress problem object and return a user function instance that can then be used in the code to build formulas.
