Constraint

public class NumericRangeConstraint
extends AbstractConstraint

Constraint implementation that ensures that the value is a numeric value bewteen a given minimum and maximum value. If a minimum or maximum value are not provided, then the JAVA Double's minimum value or maximum value are assumed.

Overrides:

toString in class Object

getMinValue

public double getMinValue()

Returns:

Returns the minimum value allowed by the constraint

setMinValue

public void setMinValue(double minValue)

Set the minimum value allowed, which can be any value between Double.MIN_VALUE and Double.MAX_VALUE.

Parameters:

minValue - the minimum value allowed by the constraint

getMaxValue

public double getMaxValue()

Returns:

Returns the minimum value allowed by the constraint

setMaxValue

public void setMaxValue(double maxValue)

Set the maximum value allowed, which can be any value between Double.MIN_VALUE and Double.MAX_VALUE.

Parameters:

maxValue - the minimum value allowed by the constraint

getParameters

public Map<String,Object> getParameters()

Description copied from interface: Constraint

Returns the parameters passed to the instance of the constraint.

getParameters in interface Constraint

Overrides:

getParameters in class AbstractConstraint

Returns:

Map of parameters or an empty Map if none exist

evaluateSingleValue

protected void evaluateSingleValue(Object value)

Description copied from class: AbstractConstraint
