SYNOPSIS

METHODS

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.

variable_re

my $variable_re = $type_class->variable_re;

This method returns the regular expression (as a qx construct) used to match the variable in parsed strings.

When parsing "4 <= x <= 10" this regular expression is used to match the letter "x."
