NAME

Bio::SearchIO::blast - Event generator for event based parsing of blast reports

SYNOPSIS

   # Do not use this object directly - it is used as part of the
   # Bio::SearchIO system.

    use Bio::SearchIO;
    my $searchio = new Bio::SearchIO(-format => 'blast',
				     -file   => 't/data/ecolitst.bls');
    while( my $result = $searchio->next_result ) {
	while( my $hit = $result->next_hit ) {
	    while( my $hsp = $hit->next_hsp ) {
		# ...
	    }
	}
    }

DESCRIPTION

This object encapsulated the necessary methods for generating events suitable for building Bio::Search objects from a BLAST report file. Read the Bio::SearchIO for more information about how to use this.
