clearCacheForRecord()
Stores a record into the stack to resolve the page IDs later-on to clear the caches on these pages then.

clearCacheForRecord(string $table, int $uid) : void
Make sure to call clearCachesOfRegisteredPageIds() afterwards.
Parameters

clearCachesOfRegisteredPageIds()
First, this method checks, if any records are registered (usually via Database Backend) to be analyzed for a page record, if so, adds additional page IDs to the pageIdStack.
public
clearCachesOfRegisteredPageIds() : void
Walks through the pageIdStack, collects all pageIds as array and passes them on to clearPageCache.
clearPageCache()
Clears the page cache
public
clearPageCache([int|array<string|int, int>|string $pageIdsToClear = null ]) : void

Return values
SplStackclearPageCacheForGivenRecord()
Finds the right PID(s) of a given record and loads the TYPO3 page cache for the given record.
protected
clearPageCacheForGivenRecord(string $tableName, int $uid) : void
If the record lies on a page, then we clear the cache of this page. If the record has no PID column, we clear the cache of the current page as best-effort.
Much of this functionality is taken from DataHandler::clear_cache() which unfortunately only works with logged-in BE user.
Parameters
- $tableName : string
-
Table name of the record
- $uid : int
-
UID of the record
