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

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

  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.
