Output
public final class KvpOutput extends WriteSession implements Output
An output for serializing kvp-encoded messages (from a byte array as source). A kvp encoding is a binary encoding w/c contains a key-value sequence. On the wire, a serialized field (key-value) would look like: [key-len][key][value-len][value]

The keys and values are length-delimited (uint16 little endian).

Note that this encoding does not support nested messages. This encoding is mostly useful for headers w/c contain information about the content it carries (see http://projects.unbit.it/uwsgi/wiki/uwsgiProtocol).
