  - setMin
```
public void setMin(double val)
```
    Sets the minimum bound.
  - getMax
```
public double getMax()

```
public boolean contains(IlvDataInterval itv)
```
    Returns whether the given interval is included within this interval.
  - translate
```
public void translate(double delta)
```
    Translates the interval from the given value. The new bounds are min+delta, max+delta.
  - expand
```
public void expand(double delta)
```
    Expands the interval from the given value. The new bounds are min-delta, max+delta. This method has no effects on an empty interval.
  - intersects
```
public boolean intersects(IlvDataInterval itv)
```
    Returns whether the given interval intersects this interval.
  - add
```
public boolean add(double val)
```
    Adds the given value to this interval. This method updates the bounds values accordingly if the value is lower than the minimum bound or greater than the maximum bound.
    
    Returns:
    
    Whether the interval bounds have changed.
  - add
```
public boolean add(IlvDataInterval itv)
```
    Adds the given interval. This method updates the bounds values depending if the minimum bound of the given interval is lower than the current minimum bound or if the maximum bound of the given interval is greater than the current maximum bound.
    The method also distinguishes two specific cases:
    - The specified interval is empty. In this case, the current interval is not modified.
    - The current interval is empty. In this case, the current interval is set to be equal to the specified interval.
    Returns:
    
    Whether the bounds of the current interval have changed.
  - subtract
```
public void subtract(IlvDataInterval itv)
```
    Subtracts the given interval. If the given interval contains the current interval, then this interval is emptied. Else, the current bounds are updated accordingly.

  - intersection
```
public void intersection(IlvDataInterval itv)
```
    Computes the intersection of this interval with the given interval and modifies this data interval accordingly.
  - getLength
```
public double getLength()
```
    Returns the length of this interval.
  - getMiddle
```
public double getMiddle()
```
    Returns the middle value of this interval.
  - clamp
```
public double clamp(double value)
```
    Clamps the specified value to this interval. The returned value is computed according to the following rules:
    - The value is returned if the interval is empty or if it contains value.
    - The minimum value of the interval is returned if value is before the interval.
    - The maximum value of the interval is returned if value is after the interval.
  - clone
```
public Object clone()
```
    Returns a copy of this data interval.
    
    Overrides:
    
    clone in class Object
  - equals
```
public boolean equals(Object obj)
```
    Returns whether this data interval is equal to the specified data interval. By definition, two data intervals are equal if both their minimum bounds and maximum bounds are equal.
    
    Overrides:
    
    equals in class Object
  - toString
```
public String toString()
```
    Returns a string representation of this data interval.
    
    Overrides:
    
    toString in class Object
