void OsiCutsUnitTest | ( | ) | [friend] |
A function that tests the methods in the OsiCuts 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.

OsiVectorColCutPtr OsiCuts::colCutPtrs_ [private] |
