      • asComparableBytes

        ByteSource asComparableBytes​(ByteComparable.Version version)
        Produce a prefix-free byte-comparable representation of the key, i.e. such a sequence of bytes that any pair x, y of valid positions (with the same key column types and partitioner), x.compareTo(y) == compareLexicographicallyUnsigned(x.asComparableBytes(), y.asComparableBytes()) and x.asComparableBytes() is not a prefix of y.asComparableBytes() We use a two-component tuple for decorated keys, and a one-component tuple for key bounds, where the terminator byte is chosen to yield the correct comparison result. No decorated key can be a prefix of another (per the tuple encoding), and no key bound can be a prefix of one because it uses a terminator byte that is different from the tuple separator.

      • asComparableBound

        ByteComparable asComparableBound​(boolean before)
        Produce a byte-comparable representation for the position before or after the key. This does nothing for token boundaries (which are already at a position between valid keys), and changes the terminator byte for keys.
