EventBusBuilder #124
Description
Do all the optional configuration using a builder pattern. Current way with configure* methods are clumsy. This allows more configuration if required.
Existing config:
- logSubscriberExceptions
- logNoSubscriberMessages
Potential new config:
- fail fast (don't send event)
- Give a thread pool for EventBus
- disable sending no-subscriber events
- allow register subscribers without event handlers (Silencing exception on registered object without onEvent method #98)
- allow unregister to succeed if subscriber was not registered before
Q: Should there be a default builder used for the default bus instance? Or should the default bus be setable?
