GRBGenConstr
Gurobi general constraint object. General constraints are always
associated with a particular model. You create a general constraint
object by adding a constraint to a model (using one of the
GRBModel::addGenConstrXxx) methods,
rather than by using a GRBGenConstr
constructor.
The methods on general constraint objects are used to get and set
general constraint attributes. For example, general constraint types
can be queried by calling
get(GRB_IntAttr_GenConstrType
).
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).
