Classes of BioSeq and SeqInfo. The class BioSeq has four methods: getBioSeqId, getLength, getAnySeq and getBioSeqVersion. The returned values of methods represent attributes of class BioSeq defined in the object model, providing information on biological sequences. The class SeqInfo has methods: getDescription, getKeywords, getComments, getDbXrefs and getReferences, representing general information on the sequences.
