Private Member Functions
Methods to block default compiler methods.
The compiler automatically generates the following three methods. Since the default compiler implementation is generally not what you want (for all but the most simple classes), we usually put the declarations of these methods in the private section and never implement them. This prevents the compiler from implementing an incorrect "default" behavior without us knowing. (See Scott Meyers book, "Effective C++")

Member Function Documentation

void KnitroSolver::buildSolverInstance ( ) throw ( ErrorClass )

virtual

buildSolverInstance is a virtual function – the actual solvers will implement their own buildSolverInstance method – the solver instance is the instance the individual solver sees in its API

Implements DefaultSolver.

Definition at line 580 of file OSKnitroSolver.cpp.

void KnitroSolver::setSolverOptions ( ) throw ( ErrorClass )

virtual

The implementation of the virtual functions.

Returns

void.

Implements DefaultSolver.

void KnitroSolver::solve ( ) throw ( ErrorClass )

virtual

solve results in an instance being read into the Knitro data structrues and optimized

Implements DefaultSolver.

void KnitroSolver::dataEchoCheck

(

)

use this for debugging, print out the instance that the solver thinks it has and compare this with the OSiL file
