Interface IloNumVar

All Superinterfaces:

IloNumExpr

All Known Subinterfaces:

IloIntVar, IloSemiContVar

public interface IloNumVar

extends IloNumExpr

This interface defines the API for numerical variables of any type. Objects implementing this interface are used to represent modeling variables in ILOG Concert Technology for Java. A modeling variable is characterized by its lower and upper bounds as well as by its type. Possible types are:

• IloNumVarType.Float
• IloNumVarType.Int
• IloNumVarType.Bool

The bounds of a variable can be changed after the variable has been constructed, but its type remains fixed throughout the lifetime of the variable object.

IloNumVarType, IloIntVar

java.lang.String	getName() Returns the name of the invoking variable.
ilog.concert.IloNumVarType	getType() Queries the type of the invoking IloNumVar object.
double	getUB() Queries the upper bound of the invoking IloNumVar object.
void	setLB(double lb) Sets the lower bound of the invoking IloNumVar object.
void	setName(java.lang.String name) Sets the name of the invoking variable.
void	setUB(double ub) Sets the upper bound of the invoking IloNumVar object.
