public function NullLockBackend::wait

public NullLockBackend::wait($name, $delay = 30)

Waits a short amount of time before a second lock acquire attempt.

While this method is subject to have a generic implementation in abstract backend implementation, some backends may provide non blocking or less I/O intensive wait mechanism: this is why this method remains on the backend interface.

Parameters

string $name: Lock name currently being locked.

int $delay: Milliseconds to wait for. Defaults to 30.

Return value

bool TRUE if the lock holds, FALSE if it may be available. You still need to acquire the lock manually and it may fail again.
