ILOG CPLEX C++ API 9.0 Reference Manual

IloCplex
This method returns the number of semi-integer variables in the matrix representation of
the active model in the invoking IloCplex object.
public IloInt getNsiftingIterations()
This method returns the number of sifting iterations performed for solving the last LP
with algorithm type IloCplex::Sifting, or, equivalently, the number of work LPs
that have been solved for it.
public IloInt getNsiftingPhaseOneIterations()
This method returns the number of sifting iterations performed for solving the last LP
with algorithm type IloCplex::Sifting in order to achieve primal feasibility.
public IloInt getNSOSs()
This method returns the number of SOSs extracted for the invoking algorithm. There
may be differences in the number returned by this function and the number of
IloNumVar, etc. in the model that is extracted. This is because piecewise linear
functions are extracted to a set of SOS.
public void getObjSA(IloNumArray lower,
IloNumArray upper,
const IloNumVarArray vars)
This method performs objecitve sensitivity analysis for the variables specified in array
vars. When this method returns lower[i] and upper[i] will contain the lowest
and highest value the objective function coefficient for variable vars[i] can assume
without affecting the optimality of the solution. The arrays lower and upper will be
resized to the size of array vars. If any of the information is not requested, 0 (zero) can
be passed for the corresponding array parameter.
public IloBool getParam(IloCplex::BoolParam parameter)
This method returns the current setting of parameter in the invoking algorithm.
See the reference manual ILOG CPLEX Parameters and the ILOG CPLEX User's
Manual for more information about these parameters. Also see the user's manual for
examples of their use.
public void getPriorities(IloNumArray pri,
const IloNumVarArray var)
This method returns query branch priorities previously assigned to variables listed in
var with the method setPriority or setPriorities. When the function
returns, pri[i] will contain the priority value assigned for variables var[i]. If no
priority has been assigned to var[i], pri[i] will contain 0 (zero).
public IloNum getPriority(IloNumVar var)
This method returns the priority previously assigned to the variable var with the
method setPriority or setPriorities. It returns 0 (zero) if no priority has
been assigned.
