java.lang.Objectgurobi.GRBQConstr
public class GRBQConstr
Gurobi quadratic constraint object. Quadratic constraints are always
associated with a particular model. You create a quadratic constraint
object by adding a quadratic constraint to a model (using GRBModel.addQConstr
), rather than by using a
GRBQConstr
constructor.
The methods on quadratic constraint objects are used to get and set
constraint attributes. For example, quadratic constraint right-hand
sides can be queried by calling get
(GRB.DoubleAttr.QCRHS
). 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
).
