Stability: newable

Note: marked as newable in 1.35 for lack of a better alternative, but should use a factory in the future.

Constructor & Destructor Documentation

◆ __construct()

PoolCounterWorkViaCallback::__construct	(		$type,
			$key,
		array	$callbacks )

Build a PoolCounterWork class from a type, key, and callback map.

The callback map must at least have a callback for the 'doWork' method. Additionally, callbacks can be provided for the 'doCachedWork', 'fallback', and 'error' methods. Methods without callbacks will be no-ops that return false. If a 'doCachedWork' callback is provided, then execute() may wait for any prior process in the pool to finish and reuse its cached result.
