Method Summary

Modifier and Type	Method	Description
protected List<String>	_getRemovingCacheEventIds(String workspace)	Returns all event ids for which the cache should be removed.
Set<String>	getPageElementTypes()	Returns the types of the associated page elements.
void	service(ServiceManager manager)
PageElementCachePolicy.PolicyResult	shouldClearCache(String workspace, Site site, String pageElementType, String elementId, Event event)	Second pass of event processing, at the Page level. This method is only called if the first pass resulted with NEED_MORE_INFORMATION.
PageElementCachePolicy.PolicyResult	shouldClearCache(String workspace, Site site, String pageElementType, Event event)	First pass of event processing, at the type level. Returning NEED_MORE_INFORMATION eventually leads to the second pass, which is more precise, and also depends on a particular element, but is more costly to compute. Returning null means that this policy declares itself as not concerned by the current event.
