Method Summary

Modifier and Type	Method	Description
boolean	get()	Returns the current value of this ObservableBooleanValue.

Methods declared in interface Observable

addListener, removeListener, subscribe

Modifier and Type	Method	Description
void	addListener(InvalidationListener listener)	Adds an InvalidationListener which will be notified whenever the Observable becomes invalid.
void	removeListener(InvalidationListener listener)	Removes the given listener from the list of listeners, that are notified whenever the value of the Observable becomes invalid.
default Subscription	subscribe(Runnable invalidationSubscriber)	Creates a Subscription on this Observable which calls invalidationSubscriber whenever it becomes invalid.

Methods declared in interface ObservableValue

addListener, flatMap, getValue, map, orElse, removeListener, subscribe, subscribe, when

Modifier and Type	Method	Description
void	addListener(ChangeListener<? super Boolean> listener)	Adds a ChangeListener which will be notified whenever the value of the ObservableValue changes.
default <U> ObservableValue<U>	flatMap(Function<? super Boolean, ? extends ObservableValue<? extends U>> mapper)	Returns an ObservableValue that holds the value of an ObservableValue produced by applying the given mapping function on this value.
Boolean	getValue()	Returns the current value of this ObservableValue
default <U> ObservableValue<U>	map(Function<? super Boolean, ? extends U> mapper)	Returns an ObservableValue that holds the result of applying the given mapping function on this value.
default ObservableValue<Boolean>	orElse(Boolean constant)	Returns an ObservableValue that holds this value, or the given constant if it is null.
void	removeListener(ChangeListener<? super Boolean> listener)	Removes the given listener from the list of listeners that are notified whenever the value of the ObservableValue changes.
default Subscription	subscribe(BiConsumer<? super Boolean, ? super Boolean> changeSubscriber)	Creates a Subscription on this ObservableValue which calls the given changeSubscriber with the old and new value whenever its value changes.
default Subscription	subscribe(Consumer<? super Boolean> valueSubscriber)	Creates a Subscription on this ObservableValue which immediately provides the current value to the given valueSubscriber, followed by any subsequent values whenever its value changes.
default ObservableValue<Boolean>	when(ObservableValue<Boolean> condition)	Returns an ObservableValue that holds this value and is updated only when condition holds true.
