Class IntegerPropertyBase

javafx.beans.property.IntegerPropertyBase

All Implemented Interfaces:: NumberExpression, Observable, Property<Number>, ReadOnlyProperty<Number>, ObservableIntegerValue, ObservableNumberValue, ObservableValue<Number>, WritableIntegerValue, WritableNumberValue, WritableValue<Number>

Direct Known Subclasses:: SimpleIntegerProperty, StyleableIntegerProperty

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 Details

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 Details

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:

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:

addListener

public void addListener(ChangeListener<? super 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:

removeListener

public void removeListener(ChangeListener<? super 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.

Parameters:

listener - The listener to remove

See Also:

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.

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()

Returns the current value of this ObservableIntegerValue.

Returns:: The current value

set

public void set(int newValue)

Set the wrapped value. Unlike WritableIntegerValue.setValue(java.lang.Number), this method uses primitive int.

Parameters:: newValue - 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

See Also:

bind

public void bind(ObservableValue<? extends Number> 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:

toString

public String toString()

Returns a string representation of this IntegerPropertyBase object.

Overrides:: toString in class IntegerProperty
Returns:: a string representation of this IntegerPropertyBase object.
