public final class JavaBeanFloatProperty extends FloatProperty implements JavaBeanProperty<Number>
JavaBeanFloatProperty provides an adapter between a regular
Java Bean property of type float or Float and a JavaFX
FloatProperty. It cannot be created directly, but a
JavaBeanFloatPropertyBuilder has to be used.
As a minimum, the Java Bean must implement a getter and a setter for the
property. If the getter of an instance of this class is called, the property of
the Java Bean is returned. If the setter is called, the value will be passed
to the Java Bean property. If the Java Bean property is bound (i.e. it supports
PropertyChangeListeners), this JavaBeanFloatProperty will be
aware of changes in the Java Bean. Otherwise it can be notified about
changes by calling fireValueChangedEvent(). If the Java Bean property
is also constrained (i.e. it supports VetoableChangeListeners), this
JavaBeanFloatProperty will reject changes, if it is bound to an
ObservableValue<Float>.
FloatProperty,
JavaBeanFloatPropertyBuilder| Modifier and Type | Method and Description |
|---|---|
void |
addListener(ChangeListener<? super Number> listener)
Adds a
ChangeListener which will be notified whenever the value
of the ObservableValue changes. |
void |
addListener(InvalidationListener listener)
Adds an
InvalidationListener which will be notified whenever the
Observable becomes invalid. |
void |
bind(ObservableValue<? extends Number> observable)
Create a unidirection binding for this
Property. |
void |
dispose()
Signals to the JavaFX property that it will not be used anymore and any
references can be removed.
|
void |
fireValueChangedEvent()
This method can be called to notify the adapter of a change of the Java
Bean value, if the Java Bean property is not bound (i.e.
|
float |
get()
Get the wrapped value.
|
Object |
getBean()
Returns the
Object that contains this property. |
String |
getName()
Returns the name of this property.
|
boolean |
isBound()
Can be used to check, if a
Property is bound. |
void |
removeListener(ChangeListener<? super Number> listener)
Removes the given listener from the list of listeners, that are notified
whenever the value of the
ObservableValue changes. |
void |
removeListener(InvalidationListener listener)
Removes the given listener from the list of listeners, that are notified
whenever the value of the
Observable becomes invalid. |
void |
set(float value)
Set the wrapped value.
|
String |
toString()
Returns a string representation of this
JavaBeanFloatProperty object. |
void |
unbind()
Remove the unidirectional binding for this
Property. |

Property.
Note that JavaFX has all the bind calls implemented through weak listeners. This means the bound property can be garbage collected and stopped from being updated.

ChangeListener which will be notified whenever the value
of the ObservableValue changes. If the same listener is added
more than once, then it will be notified more than once. That is, no
check is made to ensure uniqueness.
Note that the same actual ChangeListener instance may be safely
registered for different ObservableValues.
The ObservableValue stores a strong reference to the listener
which will prevent the listener from being garbage collected and may
result in a memory leak. It is recommended to either unregister a
listener by calling removeListener after use or to use an instance of
WeakChangeListener avoid this situation.

ObservableValue changes.
If the given listener has not been previously registered (i.e. it was never added) then this method call is a no-op. If it had been previously added then it will be removed. If it had been added more than once, then only the first occurrence will be removed.

InvalidationListener which will be notified whenever the

once. That is, no check is made to ensure uniqueness.
Note that the same actual InvalidationListener instance may be
safely registered for different Observables.
