Accessing QP Problem Data

Problem query routines and methods access information about a problem object after it has been created. They can be used at any time, even after problem modifications.

Note: Names of classes, methods, and symbolic constants in the .NET API correspond very closely to those in the Java API with these systematic exceptions:
