evaluate(FlowQuery $flowQuery, array $arguments)
Evaluate the operation on the objects inside $flowQuery->getContext(), taking the $arguments into account.
The resulting operation results should be stored using $flowQuery->setContext().
If the operation is final, evaluate should directly return the operation result.
