Description

`discrete_interval` public member functions

typedef ICL_COMPARE_DOMAIN(Compare, DomainT);

```
discrete_interval();
```
Default constructor; yields an empty interval [0,0).

explicit discrete_interval(const DomainT & val);

Constructor for a closed singleton interval [val,val]

discrete_interval(const DomainT & low, const DomainT & up, 
                  interval_bounds bounds = interval_bounds::right_open(), 
                  discrete_interval * = 0);

Interval from low to up with bounds bounds

```
domain_type lower() const;
```
```
domain_type upper() const;
```
```
interval_bounds bounds() const;
```

`discrete_interval` public static functions

static discrete_interval open(const DomainT & lo, const DomainT & up);

static discrete_interval right_open(const DomainT & lo, const DomainT & up);

static discrete_interval left_open(const DomainT & lo, const DomainT & up);

static discrete_interval closed(const DomainT & lo, const DomainT & up);
