General Constraint Attributes
These are general constraint attributes, meaning that they are associated with specific general constraints in the model. If the attribute name contains string "GenConstr", then it is for all types of general constraints. If it starts with string "Func", then it is only for function constraints.
You should use one of the various get routines to retrieve the
value of an attribute. These are described at the beginning of
this section.
For the object-oriented interfaces, general constraint attributes
are retrieved by invoking the get method on a constraint
object. For attributes that can be modified directly by the user, you
can use one of the various set methods.
Attempting to query an attribute that is not available will produce an
error. In C, the attribute query routine will return a
GRB_ERROR_DATA_NOT_AVAILABLE error code. The object-oriented
interfaces will throw an exception.
