/**
|
|
* Returns a new Observable that multicasts (shares) the original Observable. As long as there is at least one
|
|
* Subscriber this Observable will be subscribed and emitting data. When all subscribers have unsubscribed it will
|
|
* unsubscribe from the source Observable. Because the Observable is multicasting it makes the stream `hot`.
|
|
*
|
|
* This behaves similarly to .publish().refCount(), with a behavior difference when the source observable emits complete.
|
|
* .publish().refCount() will not resubscribe to the original source, however .share() will resubscribe to the original source.
|
|
* Observable.of("test").publish().refCount() will not re-emit "test" on new subscriptions, Observable.of("test").share() will
|
|
* re-emit "test" to new subscriptions.
