Doctrine\Common\Cache\RiakCache::resolveConflict PHP Method

RiakCache Class Documentation Datei anzeigen Open project: doctrine/cache

resolveConflict() protected method

Specific needs may override this method to apply alternate conflict resolutions. {@internal Riak does not attempt to resolve a write conflict, and store it as sibling of conflicted one. By following this approach, it is up to the next read to resolve the conflict. When this happens, your fetched object will have a list of siblings (read as a list of objects). In our specific case, we do not care about the intermediate ones since they are all the same read from storage, and we do apply a last sibling (last write) wins logic. If by any means our resolution generates another conflict, it'll up to next read to properly solve it.}

protected resolveConflict ( string $id, string $vClock, array $objectList ) : Riak\Object
$id	string
$vClock	string
$objectList	array
return	Riak\Object

    protected function resolveConflict($id, $vClock, array $objectList)
    {
        // Our approach here is last-write wins
        $winner = $objectList[count($objectList)];
        $putInput = new Input\PutInput();
        $putInput->setVClock($vClock);
        $mergedObject = new Object($id);
        $mergedObject->setContent($winner->getContent());
        $this->bucket->put($mergedObject, $putInput);
        return $mergedObject;
    }
