A utility module that helps in creating :gen_fsm processes that are registered in locker. Options are similar to the ones with Locker.Server.

Example

You can create a standard :gen_fsm process that is registered under locker like this:

defmodule MyFsm do
  use Locker.Fsm, lease_length: 10000

  def init(_) do
    {:ok, :initial_state, %{}}
  end
end

Similar to Locker.Server, this module also implements start/2 and start_link/2 functions and if the opts contain a key name the process will be registered by that name under Locker.Registry.

When overriding terminate/3 you will need to add call to super(reason, statename, state) similarly to Locker.Server so that the process will be properly unregistered during termination.
