NAME

Bio::SearchIO::FastHitEventBuilder - Event Handler for SearchIO events.

SYNOPSIS

# Do not use this object directly, this object is part of the SearchIO
# event based parsing system.

# to use the FastHitEventBuilder do this

use Bio::SearchIO::FastHitEventBuilder;

my $searchio = new Bio::SearchIO(-format => $format, -file => $file);

$searchio->attach_EventHandler(new Bio::SearchIO::FastHitEventBuilder);

while( my $r = $searchio->next_result ) {
 while( my $h = $r->next_hit ) {
  # note that Hits will NOT have HSPs
 }
}

DESCRIPTION

This object handles Search Events generated by the SearchIO classes and build appropriate Bio::Search::* objects from them. This object is intended for lightweight parsers which only want Hits and not deal with the overhead of HSPs. It is a lot faster than the standard parser event handler but of course you are getting less information and less objects out.
