public abstract class BooleanProperty extends ReadOnlyBooleanProperty implements Property<Boolean>, WritableBooleanValue
This class provides a full implementation of aProperty
wrapping aboolean
value.The value of a
BooleanProperty
can be get and set withObservableBooleanValue.get()
,ObservableValue.getValue()
,WritableBooleanValue.set(boolean)
, andWritableBooleanValue.setValue(Boolean)
.A property can be bound and unbound unidirectional with
Property.bind(ObservableValue)
andProperty.unbind()
. Bidirectional bindings can be created and removed withProperty.bindBidirectional(Property)
andProperty.unbindBidirectional(Property)
.The context of a
BooleanProperty
can be read withReadOnlyProperty.getBean()
andReadOnlyProperty.getName()
.Note: setting or binding this property to a null value will set the property to "false". See
WritableBooleanValue.setValue(java.lang.Boolean)

- JavaFX 2.0

toString
public String toString()
Returns a string representation of thisBooleanProperty
object.- Overrides:
toString
in classReadOnlyBooleanProperty
- Returns:
- a string representation of this
BooleanProperty
object.
-
booleanProperty
public static BooleanProperty booleanProperty(Property<Boolean> property)
Returns aBooleanProperty
that wraps aProperty
. If theProperty
is already aBooleanProperty
, it will be returned. Otherwise a newBooleanProperty
is created that is bound to theProperty
. Note: null values in the source property will be interpreted as "false"- Parameters:
property
- The sourceProperty
- Returns:
- A
BooleanProperty
that wraps theProperty
if necessary - Throws:
NullPointerException
- ifproperty
isnull
- Since:
- JavaFX 8.0
-
asObject
public ObjectProperty<Boolean> asObject()
Creates anObjectProperty
that holds the value of thisBooleanProperty
. If the value of thisBooleanProperty
changes, the value of theObjectProperty
will be updated automatically.- Overrides:
asObject
in classReadOnlyBooleanProperty
- Returns:
- the new
ObjectProperty
- Since:
- JavaFX 8.0
