Interface Codec<A,B>

All Known Implementing Classes:

BlockfileHeaderBlock.BlockfileHeaderCodec, ByteArraysCodec, Codec.FunctionalCodec, Codec.NullPassthroughCodec, GzipStatefulCodec, RawLongListCodec, StringCodec

public interface Codec<A,B>

A bi-directional Function where encoding then decoding should typically return the original value.

Nested Class Summary

Nested Classes

Modifier and Type	Interface	Description
static class	Codec.FunctionalCodec<A,B>	Build a Codec from two Functions.
static class	Codec.NullPassthroughCodec<A,B>	Skips the inner codecs when provided values are null, directly returning null.
