Detailed Description

Implements a Scheduler where time is virtualized, and TimedWait blocks the thread until mock-time is advanced.

The TimedWait implemention employs the worker's idle_callback to signal the underlying condition variable when the requested time has passed.

Member Function Documentation

virtual void net_instaweb::MockScheduler::AwaitWakeupUntilUs ( int64  wakeup_time_us )

protectedvirtual

Internal method to await a wakeup event. Block until wakeup_time_us (an absolute time since the epoch), or until something interesting (such as a call to Signal) occurs. This is virtual to permit us to mock it out (the mock simply advances time). This maybe called with 0 in case where there are no timers currently active.

Reimplemented from net_instaweb::Scheduler.

virtual void net_instaweb::MockScheduler::RegisterWorker ( QueuedWorkerPool::Sequence *  w )

virtual

These methods notify the scheduler of work sequences that may run work on it. They are only used for time simulations in MockScheduler and are no-ops during normal usage.

Reimplemented from net_instaweb::Scheduler.
