Class: MonitorMixin::ConditionVariable

Overview

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.

#broadcast

Wakes up all threads waiting for this lock.
#signal

Wakes up the first thread in line waiting for this lock.
#wait(timeout = nil)

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

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

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

def signal
  @monitor.mon_check_owner
