const mixinafIoc::RegistryShutdownHub

afIoc::RegistryShutdownHub

Event hub for notifications when the Registry shuts down. All listeners need to immutable funcs, which essentially means only const classes can contribute.

Common usage is add listeners in your service ctor:

new make(RegistryShutdownHub shutdownHub) {
  shutdownHub.addRegistryShutdownListener |->| {
    this.shutdown
  }
}

addRegistryShutdownListener

Source

abstract Void addRegistryShutdownListener(Str id, Str[] constraints, |->Void listener)

Adds a listener that will be notified when the registry shuts down. Note when shutdown listeners are called, the state of other dependent services is unassured. If your listener depends on other services use addRegistryWillShutdownListener()

Errs thrown by the listener will be logged and ignored.

Each listener has a unique id (case insensitive) that is used by the constraints for ordering. Each constraint must start with the prefix BEFORE: or AFTER:.

config.addOrdered("Breakfast", eggs)
config.addOrdered("Lunch", ["AFTER: breakfast", "BEFORE: dinner"], ham)
config.addOrdered("Dinner", pie)

addRegistryWillShutdownListener

abstract Void addRegistryWillShutdownListener(Str id, Str[] constraints, |->Void listener)

Adds a listener that will be notified when the registry shuts down. RegistryWillShutdown listeners are notified before shutdown listeners.

Errs thrown by the listener will be logged and ignored.

Each listener has a unique id (case insensitive) that is used by the constraints for ordering. Each constraint must start with the prefix BEFORE: or AFTER:.
