Clients
Codecs provide protocol encoding and decoding via netty pipelines as well as a standard filter stack that is applied to services from this codec.
A combined codec factory provides both client and server codec factories in one (when available).
Servers
Package netty3 implements the bottom finagle primitives: {{com.twitter.finagle.Server}} and a client transport in terms of the netty3 event loop.
Package netty3 implements the bottom finagle primitives: {{com.twitter.finagle.Server}} and a client transport in terms of the netty3 event loop.
Note: when {{com.twitter.finagle.builder.ClientBuilder}} and {{com.twitter.finagle.builder.ServerBuilder}} are deprecated, package netty3 can move into its own package, so that only the (new-style) clients and servers that depend on netty3 bring it in.
