Connection
Note: with the inclusion of gen_statem
in Erlang/OTP, this project is no longer necessary. See the following pull request as examples
of replacing Connection by gen_statem in existing projects:
We may release new versions if necessary to keep compatibility with Erlang/OTP and Elixir but otherwise this package is no longer recommended for new projects.
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) :: anyThere is an example of a simple TCP connection process in
examples/tcp_connection/.
