NAME

       Bio::SearchIO::psl - A parser for PSL output (UCSC)

SYNOPSIS

         use Bio::SearchIO;
         my $parser = Bio::SearchIO->new(-file   => 'file.psl',
                                        -format => 'psl');
         while( my $result = $parser->next_result ) {
         }

DESCRIPTION

       This is a SearchIO driver for PSL format.  PSL format is documented here:
       http://genome.ucsc.edu/goldenPath/help/customTrack.html#PSL

       By default it assumes PSL output came from BLAT you can override that by specifying
       -program_name => 'BLASTZ' when initializing the SearchIO object.

       rather than to the module maintainer directly. Many experienced and reponsive experts will
       be able look at the problem and quickly address it. Please include a thorough description
       of the problem with code and data examples if at all possible.

       usually preceded with a _

   new

        Usage   : my $obj = Bio::SearchIO::psl->new();
        Function: Builds a new Bio::SearchIO::psl object
        Returns : an instance of Bio::SearchIO::psl
        Args    :

   next_result
        Title   : next_result
        Usage   : my $result = $parser->next_result
        Function: Parse the next result from the data stream
        Returns : L<Bio::Search::Result::ResultI> or undef if no more results
        Args    : none

   start_element
        Title   : start_element
        Usage   : $eventgenerator->start_element
        Function: Handles a start element event
        Returns : none
        Args    : hashref with at least 2 keys 'Data' and 'Name'

   end_element
        Title   : end_element
        Usage   : $eventgenerator->end_element
        Function: Handles an end element event
        Returns : return value from the associated end_$type event handler
        Args    : hashref with at least 2 keys 'Data' and 'Name'
