       Bio::Seq::LargeSeqI - Interface class for sequences that cache their residues in a
       temporary file




       The interface class defines a group of sequence classes that do not keep their sequence
       information in memory but store it in a file. This makes it possible to work with very
       large files even with limited RAM.

       The most important consequence of file caching for sequences is that you do not want to
       inspect the sequence unless absolutely necessary. These sequences typically override the
       length() method not to check the sequence.

       The seq() method is not resettable, if you want to add to the end of the sequence you have
       to use add_sequence_as_string(), for any other sequence changes you'll have to create a
       new object.


   Mailing Lists
       User feedback is an integral part of the evolution of this and other Bioperl modules. Send
       your comments and suggestions preferably to the Bioperl mailing list.  Your participation
       is much appreciated.
                  - General discussion  - About the mailing lists

       Please direct usage questions or support issues to the mailing list:

       rather than to the module maintainer directly. Many experienced and reponsive experts will
       be able look at the problem and quickly address it. Please include a thorough description
       of the problem with code and data examples if at all possible.

   Reporting Bugs
       Report bugs to the Bioperl bug tracking system to help us keep track of the bugs and their

       The rest of the documentation details each of the object methods.  Internal methods are
       usually preceded with a _

        Title   : add_sequence_as_string
        Usage   : $seq->add_sequence_as_string("CATGAT");
        Function: Appends additional residues to an existing  object.
                  This allows one to build up a large sequence without
                  storing entire object in memory.
        Returns : Current length of sequence
        Args    : string to append
