Constructor Details

This class inherits a constructor from MergeRequests::UpdateService

Instance Method Details

#execute(merge_request) ⇒ Object

a stripped down service that only does what it must to update the assignees, and knows that it does not have to check for other updates. This saves a lot of queries for irrelevant things that cannot possibly change in the execution of this service.
