Fluo has a few simple POJOs that are used throughout the API. These classes are found in [org.apache.fluo.api.data][data-pkg]. All of these types are immutable. Except for Span, all of the types are Comparable and have hash code and equals implementations. These types work with [Bytes] and Java Strings. Internally, Fluo only works with bytes. All API methods that deal with String will convert back and forth to and from bytes using UTF-8.
[Bytes] is modeled after Java String. Its an immutable wrapper around byte[] like String is an immutable wrapper around char[]. To make building [Bytes] more efficient and easier, there is a reusable [BytesBuilder] that is modeled after StringBuilder. Call [Bytes.builder()][nb] to create a new [BytesBuilder].
