MapListenerSupport.FilterEvent

public MapListenerSupport.FilterEvent(ObservableMap map,
                                      int nId,
                                      java.lang.Object oKey,
                                      boolean fSynthetic,
                                      Filter[] aFilter)

Constructs a new lite (no values are specified) FilterEvent.

Parameters:

map - the ObservableMap object that fired the event

nId - this event's id

oKey - the key into the map

fSynthetic - true iff the event is caused by the cache internal processing such as eviction or loading

aFilter - an array of filters that caused this event

MapListenerSupport.FilterEvent

public MapListenerSupport.FilterEvent(ObservableMap map,
                                      int nId,

                                      java.lang.Object oValueNew,
                                      boolean fSynthetic,
                                      Filter[] aFilter)

Constructs a new FilterEvent.

Parameters:

map - the ObservableMap object that fired the event

nId - this event's id

oKey - the key into the map

oValueOld - the old value

oValueNew - the new value

fSynthetic - true iff the event is caused by the cache internal processing such as eviction or loading

aFilter - an array of filters that caused this event

Parameters:

map - the ObservableMap object that fired the event

nId - this event's id

oKey - the key into the map

oValueOld - the old value

oValueNew - the new value

fSynthetic - true iff the event is caused by the cache internal processing such as eviction or loading

transformState - the state describing how this event has been or should be transformed

aFilter - an array of filters that caused this event

MapListenerSupport.FilterEvent

public MapListenerSupport.FilterEvent(MapEvent event,
                                      Filter[] aFilter)
