Interface IloTransitionDistance

public interface IloTransitionDistance

An instance of this class represents a transition distance.

A transition distance is a square matrix of non-negative integers that represents a minimal distance between two interval variables. An instance of transition distance can be used in the no-overlap constraint (IloNoOverlap) and in state functions (IloStateFunction). In a no-overlap constraint the transition distance represents the minimal distance between two non-overlapping interval variables. The matrix is indexed using the integer types of interval variables in the sequence variable of the no-overlap constraint. In a state function, the transition distance represents the minimal distance between two integer states of the function.

For more information on the use of transition distance for state functions, see the concept State Functions in the C++ Reference Manual.

Method Summary

Methods

Modifier and Type	Method and Description
int	getSize() This member function returns the size of the invoking transition distance.
int	getValue(int fromState, int toState) This member function returns the value of the invoking transition distance between index fromState and index toState.
void	setValue(int fromState, int toState, int value) This member function sets the value of the invoking transition distance.

Method Detail

getSize

int getSize()

This member function returns the size of the invoking transition distance.

setValue

void setValue(int fromState,
            int toState,
            int value)

This member function sets the value of the invoking transition distance. The arguments fromState and toState must be non-negative integer indices lower than the size of the invoking transition distance. The argument value must be a non-negative integer representing the distance between index fromState and index toState.

getValue

int getValue(int fromState,
           int toState)

This member function returns the value of the invoking transition distance between index fromState and index toState. This value is a non-negative integer. The arguments fromState and toState must be non negative integer indices lower than the size of the invoking transition distance.
