javafx.beans.property.ReadOnlyFloatProperty

javafx.beans.property.FloatProperty

javafx.beans.property.FloatPropertyBase

All Implemented Interfaces:

NumberExpression, Observable, Property<java.lang.Number>, ReadOnlyProperty<java.lang.Number>, ObservableFloatValue, ObservableNumberValue, ObservableValue<java.lang.Number>, WritableFloatValue, WritableNumberValue, WritableValue<java.lang.Number>

Direct Known Subclasses:

SimpleFloatProperty

public abstract class FloatPropertyBase
extends FloatProperty

The class FloatPropertyBase is the base class for a property wrapping a float value. It provides all the functionality required for a property except for the ReadOnlyProperty.getBean() and ReadOnlyProperty.getName() methods, which must be implemented by extending classes.

Constructor Detail

FloatPropertyBase

public FloatPropertyBase()

The constructor of the FloatPropertyBase.

FloatPropertyBase

public FloatPropertyBase(float initialValue)

The constructor of the FloatPropertyBase.

Parameters:

initialValue - the initial value of the wrapped value

Method Detail

addListener

public void addListener(InvalidationListener listener)

Description copied from interface: Observable

Adds an InvalidationListener which will be notified whenever the Observable becomes invalid. 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 InvalidationListener instance may be safely registered for different Observables.

The Observable 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 WeakInvalidationListener avoid this situation.

Parameters:

listener - The listener to register

See Also:

Observable.removeListener(InvalidationListener)

removeListener

public void removeListener(InvalidationListener listener)

Description copied from interface: Observable

Removes the given listener from the list of listeners, that are notified whenever the value of the Observable becomes invalid.

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.

Parameters:

listener - The listener to remove

See Also:

Observable.addListener(InvalidationListener)

addListener

public void addListener(ChangeListener<? super java.lang.Number> listener)

Description copied from interface: ObservableValue

Adds a 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.

Parameters:

listener - The listener to register

See Also:

ObservableValue.removeListener(ChangeListener)

removeListener

public void removeListener(ChangeListener<? super java.lang.Number> listener)

Description copied from interface: ObservableValue

Removes the given listener from the list of listeners, that are notified whenever the value of the 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.

Parameters:

listener - The listener to remove

See Also:

ObservableValue.addListener(ChangeListener)

fireValueChangedEvent

protected void fireValueChangedEvent()

Sends notifications to all attached InvalidationListeners and ChangeListeners. This method is called when the value is changed, either manually by calling set(float) or in case of a bound property, if the binding becomes invalid.

invalidated

protected void invalidated()

The method invalidated() can be overridden to receive invalidation notifications. This is the preferred option in Objects defining the property, because it requires less memory. The default implementation is empty.

get

public float get()

Get the wrapped value.

Returns:

The current value

set

public void set(float v)

Set the wrapped value.

Parameters:

v - The new value

isBound

public boolean isBound()

Can be used to check, if a Property is bound.

Returns:

true if the Property is bound, false otherwise

bind

public void bind(ObservableValue<? extends java.lang.Number> rawObservable)

Create a unidirection binding for this Property.

Parameters:

rawObservable - The observable this Property should be bound to.

unbind

public void unbind()

Remove the unidirectional binding for this Property. If the Property is not bound, calling this method has no effect.

toString

public java.lang.String toString()

Returns a string representation of this FloatPropertyBase object.

Overrides:

toString in class FloatProperty

Returns:

a string representation of this FloatPropertyBase object.
