java.lang.Objectgurobi.GRBConstr
public class GRBConstr
Gurobi constraint object. Constraints are always associated with a
particular model. You create a constraint object by adding a
constraint to a model (using GRBModel.addConstr
), rather than by using a GRBConstr
constructor.
The methods on constraint objects are used to get and set constraint
attributes. For example, constraint right-hand sides can be queried by
calling get
(GRB.DoubleAttr.RHS
). Note,
however, that it is generally more efficient to query attributes for a
set of constraints at once. This is done using the attribute query
method on the GRBModel
object (GRBModel.get
).
