    • Constructor Detail

      • XPRBrelation

        public XPRBrelation(XPRBexpr l,
                    int type)
        Create a linear relation. 
             XPRBprob expl2;
     XPRBvar x1;
     XPRBexpr l1;
     XPRBrelation lr;
     expl2 = new XPRBprob("example2");
     x1 = expl2.newVar("abc3", XPRB.UI, 1, 100);
     l1 = new XPRBexpr(3.7, x1);
     lr = new XPRBrelation(l1, XPRB.G);
        Parameters:
        l - linear expression of type XPRBexpr
        type - type of the relation. Possible values:
        • XPRB.L <= (inequality)
        • XPRB.G >= (inequality)
        • XPRB.E = (equation)
        • XPRB.N non-binding

      • print

        public void print()
        Print out a (linear or quadratic) relation. 
             XPRBprob expl2;

     XPRBexpr l1;
     XPRBrelation lr;
     expl2 = new XPRBprob("example2");
     x1 = expl2.newVar("abc3", XPRB.UI, 1, 100);
     l1 = new XPRBexpr(3.7, x1);
     lr = new XPRBrelation(l1, XPRB.G);
     lr.print();
        Overrides:
        print in class  XPRBexpr

      • toString

        public java.lang.String toString()
        Provide a string representation of a relation. 
             XPRBprob expl2;
     XPRBvar x1;
     XPRBexpr l1;
     XPRBrelation lr;
     expl2 = new XPRBprob("example2");
