EventBus combines a WriteBus and a stream of its events.
writer and events are made separate to allow you to manage permissions. For example, you can pass only the writer instance to a function that should only have access to writing events, not reading all events from the bus.
Set the display name for this instance (observable or observer).
Set the display name for this instance (observable or observer).
This method modifies the instance and returns this. It does not create a new instance.
New name you set will override the previous name, if any. This might change in the future. For the sake of sanity, don't call this more than once for the same instance.
If display name is set, toString will output it instead of the standard type@hashcode string
