Methods (by generic)

• dim(Constraint): The dimensions of the constrained expression.

• size(Constraint): The size of the constrained expression.

• is_real(Constraint): Is the constraint real?

• is_imag(Constraint): Is the constraint imaginary?

• is_complex(Constraint): Is the constraint complex?

• is_dcp(Constraint): Is the constraint DCP?

• is_dgp(Constraint): Is the constraint DGP?

• residual(Constraint): The residual of a constraint

• violation(Constraint): The violation of a constraint.

• constr_value(Constraint): The value of a constraint.

• get_data(Constraint): Information needed to reconstruct the object aside from the args.

• dual_value(Constraint): The dual values of a constraint.

• dual_value(Constraint) <- value: Replaces the dual values of a constraint..

• size(ZeroConstraint): The size of the constrained expression.
