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$callbacksMap of callbacks
Exceptions
MWException
