public interface Streamable

Implementers can be written to a StreamOutput and read from a StreamInput. This allows them to be "thrown across the wire" using Elasticsearch's internal protocol. If the implementer also implements equals and hashCode then a copy made by serializing and deserializing must be equal and have the same hashCode. It isn't required that such a copy be entirely unchanged. Prefer implementing Writeable over implementing this interface where possible. Lots of code depends on this interface so this isn't always possible. Implementers of this interface almost always declare a no arg constructor that is exclusively used for creating "empty" objects on which you then call readFrom(StreamInput). Because readFrom(StreamInput) isn't part of the constructor the fields on implementers cannot be final. It is these reasons that this interface has fallen out of favor compared to Writeable.
