Instance Method Details

#if_available ⇒ Object

Acts like synchronize, except that if the lock cannot be acquired immediately, the program continues without executing the given block.

Example:

mutex = Mutex.new
# ...
mutex.if_available do
  # Some process that we only want one thread to be running at a time,
  # and we don't mind skipping if some other thread is already doing it.
  loop do
    notify_mechanics if danger_to_teh_manifold!
    sleep 60
  end
end
