Method Details

observeInputs

protected Subscription observeInputs()

Description copied from class: ObservableBase

Starts observing this observable's input(s), if any. This method is called when the number of observers goes from 0 to 1. This method is called before ObservableBase.newObserver(Object) is called for the first observer.

Specified by:

observeInputs in class ObservableBase<LiveList.Observer<? super E, ?>, QuasiListChange<? extends E>>

Returns:

subscription used to stop observing inputs. The subscription is unsubscribed (i.e. input observation stops) when the number of observers goes down to 0.
