Constructor Detail

LessConstraint

public LessConstraint(Number constraintValue)
Creates a Less-Than-Number parameter constraint.

That is, the value of the number parameter tested has to be less than the constraint value given.

Parameters:
constraintValue - the constraint value
Method Detail

test

public void test(Number t)
          throws ParameterException
Checks if the number value given by the number parameter is less than the constraint value. If not, a parameter exception is thrown.

Parameters:
t - Value to be checked whether or not it fulfills the underlying parameter constraint.
Throws:
ParameterException - if the parameter to be tested does not fulfill the parameter constraint

getDescription

public String getDescription(String parameterName)
Description copied from interface: ParameterConstraint
Returns a description of this constraint.

Parameters:
parameterName - the name of the parameter this constraint is used for
Returns:
a description of this constraint
