LongSetupValidityChecker

public LongSetupValidityChecker(Long min_value_allowed,
                        Long max_value_allowed)

Defines the checker that validates the new value as a long that is between min_value_allowed and max_value_allowed inclusive. If either the min or max is null, it will not be checked (that is to say, you can have the value limited only on a floor or ceiling value, or you can limit it for both).

Parameters:

min_value_allowed - if not null, the minimum value the value is allowed to be

max_value_allowed - if not null, the maximum value the value is allowed to be
