Class and Description
AtomPrefixes.AtomPrefix The first byte of an atom is its prefix, which contains some metadata about the atom; the first bit of an atom denotes whether it is a data atom or header atom.
AtomPrefixes.DataPrefix
AtomPrefixes.HeaderPrefix The first byte of a header atom also specifies whether it is indexed or keyed, and the header's level
AtomPrefixes.IndexedHeaderPrefix The payload of an indexed header is expected to be an unsigned variable-length lexicographically consistent integer: UnsignedLexVarint
AtomPrefixes.KeyedHeaderPrefix The payload of a keyed header is expected to be arbitrary length bytes.
AtomPrefixTypes.AtomType The first bit of a prefix is the atom type: 0 is a data atom 1 is a header atom There is also an overflow marker BaggageAtoms#OVERFLOW_MARKER that is just the empty byte array (ie, it has no prefix) and therefore lexicographically less than all other atoms
AtomPrefixTypes.BagOptionsInPrefix Some bag options are contained within the header prefix -- currently only the BagOptions.MergeBehavior
AtomPrefixTypes.HeaderType There are two different types of header.
AtomPrefixTypes.Level Levels are used by headers.
BaggageLayerException
BaggageReader Iterates over a list of atoms, interpreting them according to the baggage protocol; readers interpret data atoms and construct corresponding object representations.
BaggageWriter Used for writing out baggage atoms that adhere to the baggage protocol TODO: comments and documentation
BagKey A BagKey is used to look up data items and child bags within a baggage instance.
BagKey.Indexed An Indexed BagKey is one that uses an integer as identifier (versus arbitrary bytes for a BagKey.Keyed key)
BagKey.Keyed A Keyed BagKey is one that uses arbitrary bytes as identifier (versus an integer for BagKey.Indexed key)
BagOptions The only additional option that we propagate is the merge behavior.
BagOptions.MergeBehavior
ElementReader Iterator-like interface for reading data atoms
ElementWriter Iterator-like interface for writing atoms.
