public abstract class IntegerPropertyBase extends IntegerProperty
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.IntegerProperty| Constructor and Description |
|---|
IntegerPropertyBase()
The constructor of the
IntegerPropertyBase. |
IntegerPropertyBase(int initialValue)
The constructor of the
IntegerPropertyBase. |
| 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> rawObservable)
Create a unidirection binding for this
Property. |
protected void |
fireValueChangedEvent()
Sends notifications to all attached
InvalidationListeners and
ChangeListeners. |
int |
get()
Get the wrapped value.
|
protected void |
invalidated()
The method
invalidated() can be overridden to receive
invalidation notifications. |
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(int newValue)
Set the wrapped value.
|
String |
toString()
Returns a string representation of this
IntegerPropertyBase object. |
void |
unbind()
Remove the unidirectional binding for this
Property. |

IntegerPropertyBase.initialValue - the initial value of the wrapped valuepublic void addListener(InvalidationListener listener)
ObservableInvalidationListener 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.

ObservableObservable 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.
listener - The listener to removeObservable.addListener(InvalidationListener)public void addListener(ChangeListener<? super Number> listener)
ObservableValueChangeListener 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

listener - The listener to removeObservableValue.addListener(ChangeListener)protected void fireValueChangedEvent()
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.protected void invalidated()
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.public int get()
WritableValue.getValue(),
this method returns primitive int.
Needs to be identical to WritableValue.getValue().public void set(int newValue)
WritableIntegerValue.setValue(java.lang.Number),
this method uses primitive int.newValue - The new valuepublic boolean isBound()
Property is bound.true if the Property is bound, false
otherwiseProperty.bind(javafx.beans.value.ObservableValue)public void bind(ObservableValue<? extends Number> rawObservable)
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.
rawObservable - The observable this Property should be bound to.public void unbind()
Property.
If the Property is not bound, calling this method has no effect.public String toString()
