public IntDomainImpact(int maxdom,
                       DecisionOperator<IntVar> dop,
                       boolean smallest)
```
    Create a value selector that returns the best value wrt to its impact on domains cardinality. When an enumerated variable domain exceeds maxdom, only bounds are considered.
    
    Parameters:
    
    maxdom - a maximum domain size to satisfy to use this value selector.
    
    dop - the decision operator used to make the decision
    
    smallest - set to true to select the value with the smallest impact, set to false to select the value with the greatest impact
  - IntDomainImpact
```
public IntDomainImpact()
```
    Create a value selector for assignments that returns the best value wrt to its impact on domains cardinality. When an enumerated variable domain exceeds 100, only bounds are considered.

  - selectValue
```
public int selectValue(IntVar var)
```
    Selects and returns the value to constrained chosen variable with. The chosen value must belong to the domain of variable.
    
    Specified by:
    
    selectValue in interface IntValueSelector
    
    Returns:
    
    the value, based on the domain of variable
