XPRBrelation

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

• XPRBrelation

  public XPRBrelation(XPRBexpr l)

  See Also:

  XPRBrelation(l, XPRB.N)

• XPRBrelation

  public XPRBrelation(XPRBvar v)

  See Also:

  XPRBrelation(v, XPRB.N)

Method Detail

• print

  public void print()

  Print out a (linear or quadratic) 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);
       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");
       x1 = expl2.newVar("abc3", XPRB.UI, 1, 100);
       l1 = new XPRBexpr(3.7, x1);
       lr = new XPRBrelation(l1, XPRB.G);
       System.out.println(lr.toString());
   

  Overrides:

  toString in class  XPRBexpr
