NAME

Tree::Interval::Fast::Interval - Represents an interval in an instance of Tree::Interval::Fast

VERSION

Version 0.0.1

DESCRIPTION

An interval in an interval tree. It is meant to be used in conjuction with an instance of Tree::Interval::Fast.

SEE ALSO

Tree::Interval::Fast - The interval tree storing instances of Tree::Interval::Fast::Interval

SYNOPSIS

You can create an interval by specifying the range and the data it holds.


            

              
              
use Tree::Interval::Fast::Interval;
# create an interval representing the range (15.0, 20.0) which holds
# a simple integer
my $interval1 = Tree::Interval::Fast::Interval->new(15, 20, 10);
# another interval with more complicated data
my $interval2 = Tree::Interval::Fast::Interval->new(10.0, 30.0, [1, 2, 3]);
# this one holds a hash instead
my $interval2 = Tree::Interval::Fast::Interval->new(10.0, 30.0, { a=>1, b=>2 });
...
# can get the left/right boundaries of each of the intervals
printf "I1: (%.2f, %.2f)\n", $interval1->low, $interval1->high;
# can get the data associated with each interval
use Data::Dumper;
print Dumper $interval2->data;
