notifyAll method

void notifyAll()

Wake up all currently waiting tasks (does not store permits).

Immediately wakes all tasks currently waiting on notified. Unlike notifyOne, this does not store permits for future waiters.

Use cases:

  • Broadcast shutdown signal
  • Configuration reload for all workers
  • "Check your state" broadcast

Example:

// Graceful shutdown - wake all workers
void initiateShutdown() {
  shutdownFlag.notifyAll(); // All workers check shutdown state
}

Implementation

void notifyAll() {
  if (_closed) return;
  _epoch++;
  while (_waiters.isNotEmpty) {
    final c = _waiters.removeLast();
    if (!c.isCompleted) c.complete();
  }
}
