                  java.util.function.Function<? super E,? extends F> mapper)

Method Detail

get

public F get(int index)

Specified by:

get in interface java.util.List<E>

size

public int size()

Specified by:

size in interface java.util.Collection<E>

Specified by:

size in interface java.util.List<E>

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 F,?>,QuasiListChange<? extends F>>

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.

sourceChanged

private void sourceChanged(QuasiListChange<? extends E> change)

mappedChangeView

static <E,F> QuasiListChange<F> mappedChangeView(QuasiListChange<? extends E> change,
                                                       java.util.function.Function<? super E,? extends F> mapper)
