Method Summary

Modifier and Type	Method	Description
void	addInvalidationCallback(java.lang.Runnable callback)	Adds a callback that is invoked when an underlying tracked resource has changed.
void	addInvalidationCallback(java.util.function.Function<java.util.List<java.lang.String>,java.util.List<java.lang.String>> callback)	Adds 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.
void	addInvalidationListener(InvalidationListener listener)	Adds 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).
void	clearOnInvalidation(java.util.Map<?,?> map)	Adds a callback that clears the map.
protected void	fireInvalidationEvent()	Notifies all listeners/callbacks.
void	fireInvalidationEvent(java.util.List<java.lang.String> resources)	Notifies all listeners/callbacks.

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:

fireInvalidationEvent in interface InvalidationEventHub

addInvalidationCallback

public final void addInvalidationCallback(java.lang.Runnable callback)

Description copied from interface: InvalidationEventHub

Adds a callback that is invoked when an underlying tracked resource has changed. Does nothing in production mode.

Specified by:

addInvalidationCallback in interface InvalidationEventHub

clearOnInvalidation

public final void clearOnInvalidation(java.util.Map<?,?> map)

Description copied from interface: InvalidationEventHub

Adds a callback that clears the map.

Specified by:

clearOnInvalidation in interface InvalidationEventHub

addInvalidationListener

public final void addInvalidationListener(InvalidationListener listener)

Description copied from interface: InvalidationEventHub

Adds 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:

addInvalidationListener in interface InvalidationEventHub

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: InvalidationEventHub

Adds 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.
