Constructor & Destructor Documentation
| 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.
- Parameters:
-
string $type string $key array $callbacks Map of callbacks
- Exceptions:
-
MWException
