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 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.

Constructor Details

ReadOnlyBooleanProperty

public ReadOnlyBooleanProperty()

The constructor of ReadOnlyBooleanProperty.

Method Details

toString

public String toString()

Returns a string representation of this ReadOnlyBooleanProperty object.

Overrides:

toString in class Object

Returns:

a string representation of this ReadOnlyBooleanProperty object.

readOnlyBooleanProperty

public static ReadOnlyBooleanProperty readOnlyBooleanProperty(ReadOnlyProperty<Boolean> property)

Returns a ReadOnlyBooleanProperty that wraps a ReadOnlyProperty. If the ReadOnlyProperty is already a ReadOnlyBooleanProperty, it will be returned. Otherwise a new ReadOnlyBooleanProperty is created that is bound to the ReadOnlyProperty. Note: null values will be interpreted as "false"

Parameters:

property - The source ReadOnlyProperty

Returns:

A ReadOnlyBooleanProperty that wraps the ReadOnlyProperty if necessary

Throws:

NullPointerException - if property is null

Since:

JavaFX 8.0

asObject

public ReadOnlyObjectProperty<Boolean> asObject()

Creates a ReadOnlyObjectProperty that holds the value of this ReadOnlyBooleanProperty. If the value of this ReadOnlyBooleanProperty changes, the value of the ReadOnlyObjectProperty will be updated automatically.

Overrides:

asObject in class BooleanExpression

Returns:

the new ReadOnlyObjectProperty
