Interface IloNumVar

All Superinterfaces:

IloAddable, ilog.concert.IloCopyable, IloNumExpr

All Known Subinterfaces:

IloIntVar

public interface IloNumVar
extends IloNumExpr, IloAddable

This interface defines the API for numerical variables of any type.

Objects implementing this interface are used to represent modeling variables in IBM® ILOG® Concert Technology. 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.

Throws:

IloException

Returns:

The upper bound of the variable.

setLB

void setLB(double lb)
           throws IloException

Sets the lower bound of the invoking IloNumVar object.

Throws:

IloException

Parameters:

lb - The new lower bound of the variable.

setUB

void setUB(double ub)
           throws IloException

Sets the upper bound of the invoking IloNumVar object.

Throws:

IloException

Parameters:

ub - The new upper bound of the variable.

getName

java.lang.String getName()

Returns the name of the invoking variable.

Specified by:

getName in interface IloAddable

Returns:

The name assigned to the invoking modeling object.

setName

void setName(java.lang.String name)

Sets the name of the invoking variable.

Specified by:

setName in interface IloAddable

Parameters:

name - The name assigned to the invoking modeling object. null can be passed as argument to remove an assigned name from the invoking modeling object.
