Gecode::Int::IntVarImpBwd Class Reference

Backward iterator for ranges of integer variable implementations. More...

`#include <var-imp.hpp>`

## Constructors and initialization

| IntVarImpBwd (void)
| Default constructor.
| IntVarImpBwd (const IntVarImp *x)
| Initialize with ranges from variable implementation x.
void | init (const IntVarImp *x)
| Initialize with ranges from variable implementation x.

## Iteration control

bool | operator() (void) const
| Test whether iterator is still at a range or done.
void | operator++ (void)
| Move iterator to previous range (if possible).

## Range access

int | min (void) const
| Return smallest value of range.
int | max (void) const
| Return largest value of range.
unsigned int | width (void) const
| Return width of range (distance between minimum and maximum).

## Detailed Description

Backward iterator for ranges of integer variable implementations.

Note that this iterator is not a range iterator as the ranges are not iterated in increasing but in decreasing order.
