isValid

protected abstract boolean isValid(String value)

Method that derived classes must implement to check whether a value is valid

Parameters:

value - Value

Returns:

True if valid, false if valid

violated

protected abstract <T> ParseRestrictionViolatedException violated(ParseState<T> state,
                                                                  OptionMetadata option,
