trait Publisher
[source: scala/collection/mutable/Publisher.scala]
trait Publisher[Evt]
extends AnyRef
Publisher[A,This] objects publish events of type A to all registered subscribers. When subscribing, a subscriber may specify a filter which can be used to constrain the number of events sent to the subscriber. Subscribers may suspend their subscription, or reactivate a suspended subscription. Class Publisher is typically used as a mixin. The abstract type Pub models the type of the publisher itself.
