`void`	`whenFixed(Procedure f)` Asks that the closure is called whenever the domain of this variable is reduced to a single setValue

- Method Detail
  - getSolver
```
Solver getSolver()
```
    Returns the solver in which this variable was created.
    
    Returns:
    
    the solver in which this variable was created
  - whenFixed
```
void whenFixed(Procedure f)
```
    Asks that the closure is called whenever the domain of this variable is reduced to a single setValue
    
    Parameters:
    
    f - the closure
  - whenBoundChange
```
void whenBoundChange(Procedure f)
```
    Asks that the closure is called whenever the max or min setValue of the domain of this variable changes
    
    Parameters:
    
    f - the closure
  - whenDomainChange
```
void whenDomainChange(Procedure f)
```
    Asks that the closure is called whenever the domain change of this variable changes
    
    Parameters:
    
    f - the closure
  - propagateOnDomainChange
```
void propagateOnDomainChange(Constraint c)
```
    Asks that Constraint.propagate() is called whenever the domain of this variable changes. We say that a change event occurs.
    
    Parameters:
    
    c - the constraint for which the Constraint.propagate() method should be called on change events of this variable.
  - propagateOnFix
```
void propagateOnFix(Constraint c)
```
    Asks that Constraint.propagate() is called whenever the domain of this variable is reduced to a singleton. In such a state the variable is fixed and we say that a fix event occurs.
    
    Parameters:
    
    c - the constraint for which the Constraint.propagate() method should be called on fix events of this variable.
  - propagateOnBoundChange
```
void propagateOnBoundChange(Constraint c)
```
    Asks that Constraint.propagate() is called whenever the bound (maximum or minimum values) of the domain of this variable is changes. We say that a bound change event occurs in this case.
    
    Parameters:
    
    c - the constraint for which the Constraint.propagate() method should be called on bound change events of this variable.
  - min
```
int min()
```
    Returns the minimum of the domain of the variable
    
    Returns:
    
    the minimum of the domain of the variable
  - max
```
int max()
```
    Returns the maximum of the domain of the variable
    
    Returns:
    
    the maximum of the domain of the variable
  - size
```
int size()
```
    Returns the size of the domain of the variable
    
    Returns:
    
    the size of the domain of the variable
  - fillArray
```
int fillArray(int[] dest)
```
    Copies the values of the domain into an array.
    
    Parameters:
    
    dest - an array large enough dest.length >= size()
    
    Returns:
    
    the size of the domain and dest[0,...,size-1] contains the values in the domain in an arbitrary order
  - isFixed
```
boolean isFixed()
```
    Returns true if the domain of the variable has a single value.
    
    Returns:
    
    true if the domain of the variable is a singleton.
  - contains
```
boolean contains(int v)
```
    Returns true if the domain contains the specified value.
    
    Parameters:
    
    v - the value whose presence in the domain is to be tested
    
    Returns:
    
    true if the domain contains the specified value
  - remove
```
void remove(int v)
```
    Removes the specified value.
    
    Parameters:
    
    v - the value to remove
    
    Throws:
    
    InconsistencyException - is thrown if the domain becomes empty
  - fix
```
void fix(int v)
```
    Fix the specified value
    
    Parameters:
    
    v - the value to fix.
    
    Throws:
    
    InconsistencyException - is thrown if the value is not in the domain
  - removeBelow
```
void removeBelow(int v)
```
    Remove all the values less than a given value
    
    Parameters:
    
    v - the value such that all the values less than v are removed
    
    Throws:
    
    InconsistencyException - is thrown if the domain becomes empty
  - removeAbove
```
void removeAbove(int v)
```
    Remove all the values above a given value
    
    Parameters:
    
    v - the value such that all the values larger than v are removed
    
    Throws:
    
    InconsistencyException - is thrown if the domain becomes empty
