Method Detail

pendingProperty

public javafx.beans.value.ObservableBooleanValue pendingProperty()

Description copied from interface: AwaitingEventStream

Indicates whether there is a pending event that will be emitted by this stream in the (near) future. This may mean that an event has occurred that causes this stream to emit an event with some delay, e.g. waiting for a timer or completion of an asynchronous task.

Specified by:

pendingProperty in interface AwaitingEventStream<I>

isPending

public boolean isPending()

Specified by:

isPending in interface AwaitingEventStream<I>

observeInputs

protected final 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<java.util.function.Consumer<? super O>,O>

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.

handleEvent

private void handleEvent(I i)

handleTimeout

private void handleTimeout()

invalidatePending

private void invalidatePending()
