Writes an ISequence to a particular location, usually a file. The output is formatted according to the GFF file format. A method is also provided for quickly accessing the content in string form for applications that do not need to first write to file.

A GffParser reads from a source of text that is formatted according to the GFF flat file specification, and converts the data to in-memory ISequence objects. For advanced users, the ability to select an encoding for the internal memory representation is provided. There is also a default encoding for each alphabet that may be encountered.
