14.2.16 Class LinearConstraint


A linear constraint defines a block of constraints with the same linear domain. The domain is either a product of product of one-dimensional half-spaces (linear inequalities), a fixed value vector (equalities) or the whole space (free constraints).

The type of a linear variable is immutable; it is either free, an inequality or an equality, but the linear expression and the right-hand side can be modified.

The class is not meant to be instantiated directly, but must be created by calling the Model.variable method.




Constraint.dual – Get the dual solution values of the constraint.

Constraint.getModel – Return the model that the constraint belongs to.

Constraint.getND – Return the number of dimensions in the constraint shape.

Constraint.getShape – Return the constraint’s shape.

Constraint.getSize – Return the total number of elements in the constraint.

Constraint.index – Get a single element from a constraint.

Constraint.level – Get the primal solution values of the constraint.

Constraint.slice – Create a slice constraint.

Constraint.update – Update part of a constraint.

LinearConstraint.toString – Create a human readable string representation of the constraint.

ModelConstraint.remove – Remove the constraint from the model.

string toString()

Create a human readable string representation of the constraint.
