NAME

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

CONTENTS

SYNOPSIS



 #



DESCRIPTION

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 resetable, 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.

 Usage   : $seq->add_sequence_as_string("CATGAT");
 Function: Appends additional residues to an existing  object.
