BehaviorSubject

Subject that emits the most recent item it has observed and all subsequent observed items to each subscribed Observer.

Example:

// observer will receive all events.
val subject = BehaviorSubject[String]("default")
subject.subscribe(observer)
subject.onNext("one")
subject.onNext("two")
subject.onNext("three")

// observer will receive the "one", "two" and "three" events, but not "zero"
val subject = BehaviorSubject[String]("default")
subject.onNext("zero")
subject.onNext("one")
subject.subscribe(observer)
subject.onNext("two")
subject.onNext("three")

// observer will receive only onCompleted
val subject = BehaviorSubject[String]("default")
subject.onNext("zero")
subject.onNext("one")
subject.onCompleted()
subject.subscribe(observer)

// observer will receive only onError
val subject = BehaviorSubject[String]("default")
subject.onNext("zero")
subject.onNext("one")
subject.onError(new RuntimeException("error"))
subject.subscribe(observer)
