NAME

Geo::StormTracker::Parser - Perl extension for Parsing Weather Advisories

SYNOPSIS

        use Geo::StormTracker::Parser;

        #Create a parser object
        $parser_obj=Geo::StormTracker::Parser->new();

        #Parse input and return a Geo::StormTracker::Advisory object.
        $adv_obj=$parser_obj->read(\*STDIN);
        
        #An alternative to the read method above,
        #which accepts the advisory as a string.
        $adv_obj=$parser_obj->read_data($advisory_data); 

        #Same as above two methods but reads from a file instead.
        $adv_obj=$parser_obj->read_file($advisory_data);

DESCRIPTION

The Geo::StormTracker::Parser module is a component of the Storm-Tracker perl bundle. The Storm-Tracker perl bundle is designed to track weather events using the national weather advisories. The original intent is to track tropical depressions, storms and hurricanes. The various read methods of Geo::StormTracker::Parser take a plain text advisory as input and return Geo::StormTracker::Advisory objects.

CONSTRUCTOR

new

Creates a new instance of a Geo::StormTracker::Parser object and returns a blessed reference to it.

read_data (STRING)
