  • Bus name: cbqo:Bus/QueryOperation

Creating actors on this bus

Actors extending ActorQueryOperation or ActorQueryOperationTyped are automatically subscribed to this bus.

It is recommended to extend from ActorQueryOperationTyped if your actor supports a single query operation, as the bus will be able to handle this actor more efficiently. This is not applicable if your actor handles multiple different types of query operations.
