FIXME: This isn't documented in Nutshell.

Since MonitorMixin#new_cond returns a ConditionVariable, and the example above calls while_wait and signal, this class should be documented.

Instance Public methods
broadcast()

Wakes up all threads waiting for this lock.

Source: show 

# File lib/monitor.rb, line 146
def broadcast
  @monitor.__send__(:mon_check_owner)
  @cond.broadcast
end
signal()

Wakes up the first thread in line waiting for this lock.

Source: show 

# File lib/monitor.rb, line 138
def signal
  @monitor.__send__(:mon_check_owner)
  @cond.signal
end
wait(timeout = nil)

Releases the lock held in the associated monitor and waits; reacquires the lock on wakeup.

If timeout is given, this method returns after timeout seconds passed, even if no other thread doesn't signal.

Source: show 

# File lib/monitor.rb, line 106
def wait(timeout = nil)
  @monitor.__send__(:mon_check_owner)
  count = @monitor.__send__(:mon_exit_for_cond)
  begin
    @cond.wait(@monitor.instance_variable_get(:@mon_mutex), timeout)
    return true
  ensure
    @monitor.__send__(:mon_enter_for_cond, count)
  end
end
wait_until()

Calls wait repeatedly until the given block yields a truthy value.

Source: show 

# File lib/monitor.rb, line 129
def wait_until
  until yield
    wait
  end
end
wait_while()

Calls wait repeatedly while the given block yields a truthy value.

Source: show 

# File lib/monitor.rb, line 120
def wait_while
  while yield
    wait
  end
end
