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
quadratic 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).
