    public final class SeqIOConstants

extends Object

`SeqIOConstants` contains constants used to identify sequence formats, alphabets etc, in the context of reading and writing sequences.

An `int` used to specify symbol alphabet and sequence format type is derived thus:

- The two least significant bytes are reserved for format types such as RAW, FASTA, EMBL etc.
- The two most significant bytes are reserved for alphabet and symbol information such as AMBIGUOUS, DNA, RNA, AA etc.
- Bitwise OR combinations of each component `int` are used to specify combinations of format type and symbol information. To derive an `int` identifier for DNA with ambiguity codes in Fasta format, bitwise OR the AMBIGUOUS, DNA and FASTA values.
