• new TcpTransport(options)
• tcpTransport.close([callback])
• tcpTransport.deltas(remotePeer, localPeer, deltasToSend)
• tcpTransport.digest(remotePeer, localPeer, digestToSend)
• tcpTransport.listen([callback])
• Event 'deltas'
• Event 'digest'

TcpTransport.listen(options, callback)

• options: See new TcpTransport(options) options.
• callback: See tcpTransport.listen(callback) callback.
• Return: Object An instance of TcpTransport with server running.

Creates new TCP transport and starts the server.

new TcpTransport(options)

• options:
  • host: String (Default: 'localhost')
  • port: Integer (Default: 9742) A port value of zero will assign a random port.

Creates a new TCP transport.

tcpTransport.close(callback)

• callback: Function (Default: undefined) Optional callback to call once the server is stopped.

Stops the server from listening to requests from other peers.

tcpTransport.deltas(remotePeer, localPeer, deltasToSend)

• remotePeer: Object Peer to send rpc to.
  • transport: Object TCP transport data.
    • host: String Host to connect to.
    • port: Integer Port to connect to.
• localPeer: Object Sender peer.
  • id: String Sender peer id.
  • transport: Object TCP transport data.
    • host: String Host to connect to.
    • port: Integer Port to connect to.
• deltasToSend: Any Deltas to send.

Sends deltasToSend to the remotePeer.

tcpTransport.digest(remotePeer, localPeer, digestToSend)

• remotePeer: Object Peer to send rpc to.
  • transport: Object TCP transport data.
    • host: String Host to connect to.
    • port: Integer Port to connect to.
• localPeer: Object Sender peer.
  • id: String Sender peer id.
  • transport: Object TCP transport data.
    • host: String Host to connect to.
    • port: Integer Port to connect to.
• digestToSend: Any Digest to send.

Sends digestToSend to the remotePeer.

tcpTransport.listen(callback)

• callback: Function (Default: undefined) Optional callback to call once the server is up.

Starts the server to listen to requests from other peers.

tcpTransport.rpc(remotePeer, payload)

CAUTION: reserved for internal use

• remotePeer: Object Peer to send rpc to.
  • transport: Object TCP transport data.
    • host: String Host to connect to.
    • port: Integer Port to connect to.
• payload: String or Object Payload is send on the wire. If an Object is provided, it will be JSON.stringify()'ed.

An internal common implementation for tcpTransport.deltas(...) and tcpTransport.digest(...).

Event deltas

• remotePeer: Object
  • id: String Id of the peer.
  • transport: Any Any data identifying this peer to the transport mechanism that is required for correct transport operation.
• deltas: Any Received deltas.

Emitted when TcpTransport receives deltas from a peer.

Event digest

• remotePeer: Object
  • id: String Id of the peer.
  • transport: Any Any data identifying this peer to the transport mechanism that is required for correct transport operation.
• digest: Any Received digest.

Emitted when TcpTransport receives digest from a peer.
