NAME

Range::Object::Serial - Implements ranges of integer identificators

SYNOPSIS

use Range::Object::Serial;

# Create a new range
my $range = Range::Object::Serial->new('1-10, 12, 15', 17..20);

# Test if a value is in range
print "in range\n"     if  $range->in(5);
print "not in range\n" if !$range->in(11);

# Add values to range
$range->add(11, '13-14;16');

# Get full list of values
my @list = $range->range();
print join q{ }, @list;         # Prints 1 2 3 4 5 ... 20

# Get collapsed string representation
my $string = $range->range();
print "$string\n";              # Prints '1-20'

# Get range size
my $size = $range->size();
print "$size";                  # Prints: 20
