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 Class Methods

Public Instance Methods

broadcast() click to toggle source

Wakes up all threads waiting for this lock.

 
               # File monitor/lib/monitor.rb, line 139
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 131
def signal
  @monitor.mon_check_owner
  @cond.signal
end
            
wait(timeout = nil) click to toggle source

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.

 
               # File monitor/lib/monitor.rb, line 105
def wait(timeout = nil)
  @monitor.mon_check_owner
  @monitor.wait_for_cond(@cond, timeout)
end

  end
end
