# 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 Class Methods

new(monitor) click to toggle source

    # File lib/monitor.rb, line 158
    def initialize(monitor)
      @monitor = monitor
      @cond = Thread::ConditionVariable.new
    end

### Public Instance Methods

broadcast() click to toggle source

Wakes up all threads waiting for this lock.

    # File lib/monitor.rb, line 151
    def broadcast
      @monitor.__send__(:mon_check_owner)
      @cond.broadcast
    end

signal() click to toggle source

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

    # File lib/monitor.rb, line 143
    def signal
      @monitor.__send__(: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 lib/monitor.rb, line 107
    def wait(timeout = nil)
      Thread.handle_interrupt(EXCEPTION_NEVER) do
        @monitor.__send__(:mon_check_owner)
        count = @monitor.__send__(:mon_exit_for_cond)
        begin
          Thread.handle_interrupt(EXCEPTION_IMMEDIATE) do
            @cond.wait(@monitor.instance_variable_get(:@mon_mutex), timeout)
          end
          return true
        ensure
          @monitor.__send__(:mon_enter_for_cond, count)
        end
      end
    end

wait_until() click to toggle source

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

    # File lib/monitor.rb, line 134
    def wait_until
      until yield
        wait
      end
    end

wait_while() click to toggle source

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

    # File lib/monitor.rb, line 125
    def wait_while
      while yield
        wait
      end
    end
