PHP Класс Neos\Cache\Backend\ApcBackend

This backend uses the following types of keys: - entry_xxx the actual cache entry with the data to be stored - tag_xxx xxx is tag name, value is array of associated identifiers identifier. This is "forward" tag index. It is mainly used for obtaining content by tag (get identifier by tag -> get content by identifier) - ident_xxx xxx is identifier, value is array of associated tags. This is "reverse" tag index. It provides quick access for all tags associated with this identifier and used when removing the identifier - tagIndex Value is a List of all tags (array) Each key is prepended with a prefix. By default prefix consists from two parts separated by underscore character and ends in yet another underscore character: - "Flow" - MD5 of path to Flow and the current context (Production, Development, ...) This prefix makes sure that keys from the different installations do not conflict. Показать файл Открыть проект Примеры использования класса

flush ( ) : void	Removes all cache entries of this cache.
flushByTag ( string $tag ) : integer	Removes all cache entries of this cache which are tagged by the specified tag.
get ( string $entryIdentifier ) : mixed	Loads data from the cache.
getPrefixedIdentifier ( string $entryIdentifier ) : string	Returns the internally used, prefixed entry identifier for the given public entry identifier.
has ( string $entryIdentifier ) : boolean	Checks if a cache entry with the specified identifier exists.
key ( ) : string	Returns the identifier of the current cache entry pointed to by the cache entry iterator.
next ( ) : void	Move forward to the next cache entry
remove ( string $entryIdentifier ) : boolean	Removes all cache entries matching the specified identifier.
