Gurobi temporary constraint object. Objects of this class are created as intermediate results when building constraints using overloaded operators. There are no member functions on this class. Instead, TempConstr objects are created by a set of functions on Var, LinExpr, and QuadExpr objects (e.g., ==, <=, and >=). You will generally never store objects of this class in your own variables.

Consider the following examples:

  model.addConstr(x + y <= 1);
  model.addQConstr(x*x + y*y <= 1);
The overloaded <= operator creates an object of type TempConstr, which is then immediately passed to method Model.addConstr or Model.addQConstr.
