Reference documentation and code samples for the Cloud Build v1 API class PullRequestFilter.
PullRequestFilter contains filter properties for matching GitHub Pull
Requests.
public PullRequestFilter.Types.CommentControl CommentControl { get; set; }
If CommentControl is enabled, depending on the setting, builds may not
fire until a repository writer comments /gcbrun on a pull
request or /gcbrun is in the pull request description.
Only PR comments that contain /gcbrun will trigger builds.
If CommentControl is set to disabled, comments with /gcbrun from a user
with repository write permission or above will
still trigger builds to run.
