Constructor Detail

JboRangeValidator

public JboRangeValidator()
Creates an uninitialized range validator.

The methods setMin() and setMax() must be invoked to set the range.


JboRangeValidator

public JboRangeValidator(boolean inverse,
                         java.lang.Object minValue,
                         java.lang.Object maxValue)
Creates a range validator.
Parameters:
inverse - if true the logic of this validator's comparison relation is inverted.
minValue - the least value of the range.
maxValue - the greatest value of the range.
Method Detail

initialize

protected void initialize()
Overrides:
initialize in class JboBaseValidator

setNewValue

protected void setNewValue(java.lang.Object newValue)
                    throws java.lang.Exception
after setting the new value, prepare the comparator to be of same type if it is not already so.
Overrides:
setNewValue in class JboBaseValidator
Parameters:
newValue - either the attribute's value or a value to use to compare in the validator.
java.lang.Exception

validateValue

public boolean validateValue(java.lang.Object value)
Validates that a value is in a pre-defined range.

The range is set using the setMin() and setMax() methods.

This method is called by JboBaseValidator#vetoableChange().

Specified by:
validateValue in interface JbiValidator
Specified by:
validateValue in class JboBaseValidator
Parameters:
value - the object to be validated.
Returns:
true if the relation is in the range.

setMin

public void setMin(java.lang.Object minValue)
Sets the minimum value for the range.

setMax

public void setMax(java.lang.Object maxValue)
Sets the maximum value for the range.

getMin

public java.lang.Object getMin()
Gets the minimum value for the range.
Returns:
the minimum value.

getMax

public java.lang.Object getMax()
Gets the maximum value for the range.
Returns:
the maximum value.

toString

public java.lang.String toString()
Internal: For debugging only.
Overrides:
toString in class java.lang.Object
