public final class JavaBeanFloatProperty
extends FloatProperty
implements JavaBeanProperty<Number>
A 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 class must implement a getter and a setter for the property. The class, as well as the getter and a setter methods, must be declared public. 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 ReadOnlyJavaBeanProperty.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>.

Deploying an Application as a Module

If the Java Bean class is in a named module, then it must be reflectively accessible to the javafx.base module. A class is reflectively accessible if the module opens the containing package to at least the javafx.base module.

For example, if com.foo.MyBeanClass is in the foo.app module, the module-info.java might look like this:

module foo.app {
    opens com.foo to javafx.base;
}

Alternatively, a class is reflectively accessible if the module exports the containing package unconditionally.

Method Details

get

public float get()
Get the wrapped value. Unlike WritableValue.getValue(), this method returns primitive float. Needs to be identical to WritableValue.getValue().
Specified by:
get in interface ObservableFloatValue
Specified by:
get in interface WritableFloatValue
Returns:
The current value
Throws:
UndeclaredThrowableException - if calling the getter of the Java Bean property throws an IllegalAccessException or an InvocationTargetException.

set

public void set(float value)
Set the wrapped value. Unlike WritableFloatValue.setValue(java.lang.Number), this method uses primitive float.
Specified by:
set in interface WritableFloatValue
Parameters:
value - The new value
Throws:
UndeclaredThrowableException - if calling the getter of the Java Bean property throws an IllegalAccessException or an InvocationTargetException.

toString

public String toString()
Returns a string representation of this JavaBeanFloatProperty object.
Overrides:
toString in class FloatProperty
Returns:
a string representation of this JavaBeanFloatProperty object.
