class MonitorMixin::ConditionVariable

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.

Public Instance Methods

broadcast() click to toggle source

Wakes up all threads waiting for this lock.

# File monitor/lib/monitor.rb, line 140
def broadcast
  @monitor.mon_check_owner
  @cond.broadcast
end
signal() click to toggle source

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

# File monitor/lib/monitor.rb, line 132

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

# File monitor/lib/monitor.rb, line 106
def wait(timeout = nil)
  @monitor.mon_check_owner
  @monitor.wait_for_cond(@cond, timeout)
end
