public function VoteResultFunctionManager::recalculateResults in Voting API 8.3

Recalculates the aggregate voting results of all votes for a given entity.

Loads all votes for a given piece of content, then calculates and caches the aggregate vote results. This is only intended for modules that have assumed responsibility for the full voting cycle: the votingapi_set_vote() function recalculates automatically.

Parameters

string $entity_type_id: A string identifying the type of content being rated. Node, comment, aggregator item, etc.

string $entity_id: The key ID of the content being rated.

string $vote_type: The type of vote cast.
