| useCache($depends = array() X-Ref |
| public method to determine whether the cache can be used to assist in centralisation of event triggering and calculation of cache statistics, don't override this function override makeDefaultCacheDecision() return: bool true if cache can be used, false otherwise param: array $depends array of cache dependencies, support dependecies: |
| makeDefaultCacheDecision() X-Ref |
| internal method containing cache use decision logic this function processes the following keys in the depends array purge - force a purge on any non empty value age - expire cache if older than age (seconds) files - expire cache if any file in this array was updated more recently than the cache Note that this function needs to be public as it is used as callback for the event handler can be overridden return: bool see useCache() |
| addDependencies() X-Ref |
| add dependencies to the depends array this method should only add dependencies, it should not remove any existing dependencies and it should only overwrite a dependency when the new value is more stringent than the old |
| retrieveCache($clean = true) X-Ref |
| retrieve the cached data return: string cache contents param: bool $clean true to clean line endings, false to leave line endings alone |
| storeCache($data) X-Ref |
| cache $data return: bool true on success, false otherwise param: string $data the data to be cached |
| removeCache() X-Ref |
| remove any cached data associated with this cache instance |
| stats($success) X-Ref |
| Record cache hits statistics. (Only when debugging allowed, to reduce overhead.) return: bool pass-thru $success value param: bool $success result of this cache use attempt |
| isNoCache() X-Ref |
return: bool |
