Friends And Related Function Documentation

void CglLiftAndProjectUnitTest const OsiSolverInterface *  siP,
const std::string  mpdDir
[friend]
 

A function that tests the methods in the CglLiftAndProject class.

The only reason for it not to be a member method is that this way it doesn't have to be compiled into the library. And that's a gain, because the library should be compiled with optimization on, but this method should be compiled with debugging.
