## Interface RemotingConnection

- All Superinterfaces:
    BufferHandler
  All Known Implementing Classes:
    AbstractRemotingConnection

      public interface RemotingConnection
      extends BufferHandler

  A RemotingConnection is a connection between a client and a server. Perhaps a better name for this class now would be ProtocolConnection as this represents the link with the used protocol
