Constraints

class Constraint

An object for constraint expressions that represent equality constraints or inequality constraints.

Public Functions

Expression lower() const

Returns:: the expression for the constraint lower bound

Expression body() const

Returns:: the expression for the constraint body

Expression upper() const

Returns:: the expression for the constraint upper bound

Constraint &name(const std::string &name): Set the constraint name

std::string name() const

Returns:: the constraint name

size_t id() const

Returns:: the unique integer constraint ID

std::list<std::string> to_list() const
