    next_seq



 Title   : next_seq
 Usage   : $seq = $stream->next_seq()
 Function: returns the next sequence in the stream
 Returns : Bio::Seq object, or nothing if no more available
 Args    : NONE



    write_seq



 Title   : write_seq
 Usage   : $stream->write_seq(@seq)
 Function: Writes the $seq object into the stream
 Returns : 1 for success and 0 for error
 Args    : Array of 1 or more Bio::PrimarySeqI objects



    width



 Title   : width
 Usage   : $obj->width($newval)
 Function: Get/Set the line width for FASTA output (not counting whitespace).
 Returns : value of width
 Args    : newvalue (optional)



    block



 Title   : block
 Usage   : $obj->block($newval)
 Function: Get/Set the length of each block for FASTA output. Sequence blocks
           will be split with a space. Configuring block, to a value of 10 for
           example, allows to easily indentify a position in a sequence by eye.
 Default : same value used for width.
 Returns : value of block
 Args    : newvalue (optional)



    preferred_id_type



 Title   : preferred_id_type
 Usage   : $obj->preferred_id_type(accession)
 Function: Get/Set the preferred type of identifier to use in the ">ID" position
           for FASTA output.
 Returns : string, one of values defined in @Bio::SeqIO::fasta::SEQ_ID_TYPES.
 Default : display
 Args    : string when setting. This must be one of values defined in
           @Bio::SeqIO::fasta::SEQ_ID_TYPES. Allowable values:
           accession, accession.version, display, primary
 Throws  : fatal exception if the supplied id type is not in @SEQ_ID_TYPES.
