GRBModel.getGenConstrPWL

Retrieve the data associated with a general constraint of type PWL. Calling this method for a general constraint of a different type leads to an exception. You can query the GenConstrType attribute to determine the type of the general constraint.

Typical usage is to call this routine twice. In the first call, you specify the requested general constraint, with a null value for the xpts and ypts arguments. The routine returns the length for the xpts and ypts arrays in npts. That allows you to make certain that the xpts and ypts arrays are of sufficient size to hold the result of the second call.

See also addGenConstrPWL for a description of the semantics of this general constraint type.

void getGenConstrPWL ( GRBGenConstr genc,
    GRBVar[] xvar,
    GRBVar[] yvar,
    int[] npts,
    double[] xpts,
    double[] ypts )
    Arguments:

    genc: The general constraint object.

    Any of the following arguments can be null.

    xvar: Store the <span>$</span>x<span>$</span> variable.

    yvar: Store the <span>$</span>y<span>$</span> variable.

    npts: Store the number of points that define the piecewise-linear function.

    xpts: The <span>$</span>x<span>$</span> values for the points that define the piecewise-linear function.

    ypts: The <span>$</span>y<span>$</span> values for the points that define the piecewise-linear function.
