Class IntegerPropertyBase

java.lang.Object

IntegerExpression

javafx.beans.property.ReadOnlyIntegerProperty

javafx.beans.property.IntegerProperty

javafx.beans.property.IntegerPropertyBase

All Implemented Interfaces:

Property<java.lang.Number>, ReadOnlyProperty<java.lang.Number>

Direct Known Subclasses:

SimpleIntegerProperty

public abstract class IntegerPropertyBase
extends IntegerProperty

The class IntegerPropertyBase is the base class for a property wrapping a int 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.

Since:

JavaFX 2.0

Constructor Detail

IntegerPropertyBase

public IntegerPropertyBase()

The constructor of the IntegerPropertyBase.

IntegerPropertyBase

public IntegerPropertyBase(int initialValue)

The constructor of the IntegerPropertyBase.

Parameters:

initialValue - the initial value of the wrapped value

Method Detail

addListener

public void addListener(InvalidationListener listener)

removeListener

public void removeListener(InvalidationListener listener)

addListener

public void addListener(<any> listener)

removeListener

public void removeListener(<any> listener)

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(int) or in case of a bound property, if the binding becomes invalid.

markInvalid

private void markInvalid()

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 int get()

set

public void set(int newValue)

isBound

public boolean isBound()

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

Returns:

true if the Property is bound, false otherwise

See Also:

#bind(javafx.beans.value.ObservableValue)

bind

public void bind(<any> rawObservable)

Create a unidirection binding for this 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.

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.

See Also:

#bind(javafx.beans.value.ObservableValue)

toString

public java.lang.String toString()

Returns a string representation of this IntegerPropertyBase object.

Overrides:

toString in class IntegerProperty

Returns:

a string representation of this IntegerPropertyBase object.
