Method Detail
-
fireInvalidationEvent
protected final void fireInvalidationEvent()
Notifies all listeners/callbacks.
-
fireInvalidationEvent
public final void fireInvalidationEvent(java.util.List<java.lang.String> resources)
Notifies all listeners/callbacks.- Specified by:
fireInvalidationEventin interfaceInvalidationEventHub
-
addInvalidationCallback
public final void addInvalidationCallback(java.lang.Runnable callback)
Description copied from interface:InvalidationEventHubAdds a callback that is invoked when an underlying tracked resource has changed. Does nothing in production mode.- Specified by:
addInvalidationCallbackin interfaceInvalidationEventHub
-
clearOnInvalidation
public final void clearOnInvalidation(java.util.Map<?,?> map)
Description copied from interface:InvalidationEventHubAdds a callback that clears the map.- Specified by:
clearOnInvalidationin interfaceInvalidationEventHub
-
addInvalidationListener
public final void addInvalidationListener(InvalidationListener listener)
Description copied from interface:InvalidationEventHubAdds a listener, who needs to know when an underlying resource of a given category has changed (so that the receiver may discard any cached data that may have been invalidated). Does nothing in production mode.- Specified by:
addInvalidationListenerin interfaceInvalidationEventHub
-
addInvalidationCallback
public void addInvalidationCallback(java.util.function.Function<java.util.List<java.lang.String>,java.util.List<java.lang.String>> callback)
Description copied from interface:InvalidationEventHubAdds a callback, as a function that receives a list of strings and also returns a list of strings, that is invoked when one or more listed underlying tracked resource have changed. An empty list should be considered as all resources being changed and any caches needing to be cleared. The return value of the function should be a non-null, but possibly empty, list of other resources that also need to be invalidated in a recursive fashion. This method does nothing in production mode.- Specified by:
