Connection

Connection behaviour for connection processes. The API is superset of the GenServer API. There are 2 additional callbacks connect/2 and disconnect/2:

  @callback init(any) ::
    {:ok, any} | {:ok, any, timeout | :hibernate} |
    {:connect, any, any} |
    {:backoff, timeout, any} | {:backoff, timeout, any, timeout | :hibernate} |
    :ignore | {:stop, any}

  @callback connect(any, any) ::
    {:ok, any} | {:ok, any, timeout | :hibernate} |
    {:backoff, timeout, any} | {:backoff, timeout, any, timeout | :hibernate} |
    {:stop, any, any}

  @callback disconnect(any, any) ::
    {:connect, any, any} |
    {:backoff, timeout, any} | {:backoff, timeout, any, timeout | :hibernate} |
    {:noconnect, any} | {:noconnect, any, timeout | :hibernate}
    {:stop, any, any}

  @callback handle_call(any, {pid, any}, any) ::
    {:reply, any, any} | {:reply, any, any, timeout | :hibernate} |
    {:noreply, any} | {:noreply, any, timeout | :hibernate} |
    {:disconnect | :connect, any, any} |
    {:disconnect | :connect, any, any, any} |
    {:stop, any, any} | {:stop, any, any, any}

  @callback handle_cast(any, any) ::
    {:noreply, any} | {:noreply, any, timeout | :hibernate} |
    {:disconnect | :connect, any, any} |
    {:stop, any, any}

  @callback handle_info(any, any) ::
    {:noreply, any} | {:noreply, any, timeout | :hibernate} |
    {:disconnect | :connect, any, any} |
    {:stop, any, any}

  @callback code_change(any, any, any) :: {:ok, any}

  @callback terminate(any, any) :: any

There is an example of a simple TCP connection process in examples/tcp_connection/.
