Constructor Detail

ConverterCollections.ConverterMapEvent

public ConverterCollections.ConverterMapEvent(ObservableMap map,
                                              MapEvent event,
                                              Converter convKey,
                                              Converter convVal)

Constructor.

Parameters:

event - the underlying MapEvent

map - the new event's source

convKey - the Converter to view the underlying MapEvent's key

convVal - the Converter to view the underlying MapEvent's values

Method Detail

getKey

public java.lang.Object getKey()

Return a key associated with this event.

Overrides:

getKey in class MapEvent

Returns:

a key

getOldValue

public java.lang.Object getOldValue()

The old value represents a value deleted from or updated in a map. It is always null for "insert" notifications.

Overrides:

getOldValue in class MapEvent

Returns:

an old value

getNewValue

public java.lang.Object getNewValue()

Return a new value associated with this event.

The new value represents a new value inserted into or updated in a map. It is always null for "delete" notifications.

Overrides:

getNewValue in class MapEvent

Returns:

a new value

getMapEvent

public MapEvent getMapEvent()

Return the underlying MapEvent.

Returns:

the underlying MapEvent

getConverterKeyUp

public Converter getConverterKeyUp()

Return the Converter used to view the underlying MapEvent's key through.

Returns:

the Converter from the underlying MapEvent's key

getConverterValueUp

public Converter getConverterValueUp()

Return the Converter used to view the underlying MapEvent's value through.

Returns:

the Converter from the underlying MapEvent's value

setKey

public void setKey(java.lang.Object oKey)

Set the cached converted old value associated with this event.

Parameters:

oKey - the converted key value

setOldValue

public void setOldValue(java.lang.Object oValue)

Set the cached converted old value associated with this event.

Parameters:

oValue - the new converted "old" value

setNewValue

public void setNewValue(java.lang.Object oValue)

Set the cached converted new value associated with this event.

Parameters:

oValue - the new converted "new" value

isKeyConverted

public boolean isKeyConverted()

Check if the event's key has been converted.

Returns:

true iff the key has been converted

isOldValueConverted

public boolean isOldValueConverted()

Check if the event's old value has been converted.
