◆ fireEventScheduler

final EventScheduler com.realtime.crossfire.jxclient.items.AbstractItemView.fireEventScheduler = new EventScheduler(100, 1, fireEventCallback)

private

The EventScheduler for delaying event generation.

◆ locationListeners

final IndexedEventListenerList<LocationListener> com.realtime.crossfire.jxclient.items.AbstractItemView.locationListeners = new IndexedEventListenerList<>()

private

The registered ItemListeners to be notified about changes.

Definition at line 48 of file AbstractItemView.java.

◆ locationsListeners

final EventListenerList2<LocationsListener> com.realtime.crossfire.jxclient.items.AbstractItemView.locationsListeners = new EventListenerList2<>()

private

The registered LocationsListeners to be notified about changes.

Definition at line 41 of file AbstractItemView.java.

◆ modifiedSlots

final Collection<Integer> com.realtime.crossfire.jxclient.items.AbstractItemView.modifiedSlots = new HashSet<>()

private

The pending modified floor slots to be reported to listeners.

Definition at line 54 of file AbstractItemView.java.

◆ sync

final Object com.realtime.crossfire.jxclient.items.AbstractItemView.sync = new Object()

private

The synchronization object for accesses to modifiedSlots.
