  - onEvent
```
public void onEvent(ObservableEvent<V> event)
```
    Description copied from interface: EventListener
    
    This method is called if an event occurred.
    WARNING:
    Depending on the implementation of EventSource it may NOT be legal to add or remove listeners during the call of this method as this may lead to a dead-lock.
    
    Specified by:
    
    onEvent in interface EventListener<V>
    
    Parameters:
    
    event - is the event that notifies about something that happened.
  - isMatchedUsingEquals
```
public boolean isMatchedUsingEquals()
```
    Specified by:
    
    isMatchedUsingEquals in interface EventListener<V>
    
    Returns:
    
    true if to match using equals, false to match via object identity (compared using ==). For better performance the default is false. If you implement this interface as a class overriding equals in order to being able to remove the EventListener without keeping its reference by creating a new equal EventListener instance, then you simply need to override this method returning true.
  - equals
```
public boolean equals(Object obj)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - unbind
```
public void unbind()
```

    WritableObservableValue.unbindTwoWay(WritableObservableValue)
  - bind
```
public static <V> BidirectionalBinding<V> bind(WritableObservableValue<V> property1,
                                               WritableObservableValue<V> property2)
```
    Type Parameters:
    
    V - type of observed value.
    
    Parameters:
    
    property1 - the first WritableObservableValue to bind.
    
    property2 - the second WritableObservableValue to bind.
    
    Returns:
    
    the BidirectionalBinding.
    
    See Also:
    
    WritableObservableValue.bindTwoWay(WritableObservableValue)
  - unbind
```
public static <V> void unbind(WritableObservableValue<V> property1,
                              WritableObservableValue<V> property2)
```
    Type Parameters:
    
    V - type of observed value.
    
    Parameters:
    
    property1 - the first WritableObservableValue to unbind.
    
    property2 - the second WritableObservableValue to unbind.
