NAME

Bio::Graphics::FeatureFile::Iterator -- Iterator across a Bio::Graphics::FeatureFile

SYNOPSIS

            

              
              
use Bio::Graphics::FeatureFile;
my $data  = Bio::Graphics::FeatureFile->new(-file => 'features.txt');
my $iterator = $data->get_seq_stream;
while (my $feature = $iterator->next_seq) {
  print $feature->display_id,"\t",$feature->start,"\t",$feature->end,"\n";
}
            
          

DESCRIPTION

This is a Bio::SeqIO-like object that recognizes the next_seq() and next_feature() methods. The two methods are synonymous.

There is also a rewind() method which will start iterating from the beginning again.
