removeListener(ChangeListener<? super java.lang.String> changeListener)
Removes the given listener from the list of listeners, that are notified
whenever the value of the
ObservableValue changes. |

public void addListener(ChangeListener<? super java.lang.String> changeListener)
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
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.

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.
