public abstract class DoublePropertyBase extends DoubleProperty
DoublePropertyBase
is the base class for a property
wrapping a double
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.DoubleProperty

Modifier and Type | Method and Description |
---|---|
void |
addListener(ChangeListener<? super java.lang.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 java.lang.Number> rawObservable)
Create a unidirection binding for this
Property . |
protected void |
fireValueChangedEvent()
Sends notifications to all attached
InvalidationListeners and
ChangeListeners . |
double |
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 java.lang.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(double v)
Set the wrapped value.

Returns a string representation of this
DoublePropertyBase object. |

Observable
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.

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.

ObservableValue
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

This method is called when the value is changed, either manually by
calling set(double)
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

defining the property, because it requires less memory.
