Method: Bio::Alignment::OriginalAlignment#store

Defined in:

lib/bio/alignment.rb

#store(key, seq) ⇒ Object

stores a sequence with key (name or definition of the sequence). Unlike __store__ method, the method doesn’t allow same keys. If the key is already used, returns nil. When succeeded, returns key.

# File 'lib/bio/alignment.rb', line 1628

  if @seqs.has_key?(key) then
    # don't allow same key
    # New key is discarded, while existing key is preserved.
    key = nil
  end
