# Bio::Graphics::FeatureFile::Iterator(3pm)

## 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.
