Number::Tolerant::Type - a type of tolerance
valid_args my @args = $type_class->valid_args(@_); If the arguments to "valid_args" are valid arguments for this type of tolerance, this method returns their canonical form, suitable for passing to "construct". Otherwise this method returns false. construct my $object_guts = $type_class->construct(@args); This method is passed the output of the "valid_args" method, and should return a hashref that will become the guts of a new tolerance. parse my $tolerance = $type_class->parse($string); This method returns a new, fully constructed tolerance from the given string if the given string can be parsed into a tolerance of this type. number_re my $number_re = $type_class->number_re; This method returns the regular expression (as a "qx" construct) used to match number in parsed strings. normalize_number my $number = $type_class->normalize_number($input); This method will decide whether the given input is a valid number for use with Number::Tolerant and return it in a canonicalized form. Math::BigInt objects are returned intact. Strings holding numbers are also returned intact. Strings that appears to be fractions are converted to Math::BigRat objects. Anything else is considered invalid, and the method will return false. variable_re my $variable_re = $type_class->variable_re; This method returns the regular expression (as a "qr" construct) used to match the variable in parsed strings. When parsing "4 <= x <= 10" this regular expression is used to match the letter "x."
