__construct() публичный Метод

public __construct ( StopwatchHelper $stopwatch, AbstractCache $distributedCache, AbstractCache $fastCache )
$stopwatch	Jarves\StopwatchHelper
$distributedCache	Jarves\Cache\Backend\AbstractCache
$fastCache	Jarves\Cache\Backend\AbstractCache

deleteDistributedCache() публичный Метод

Deletes a distributed cache

public deleteDistributedCache ( string $key )
$key	string

getDistributedCache() публичный Метод

This uses cache invalidation mechanism described in

public getDistributedCache ( string $key ) : mixed
$key	string
Результат	mixed	null when not found

getFastCache() публичный Метод

Returns a local cache value.

public getFastCache ( string $key ) : mixed
$key	string
Результат	mixed	null when not found

invalidateCache() публичный Метод

This is the distributed cache controller. Use it if you want to invalidate caches on a distributed backend (setDistributedCache() and getDistributedCache()). You don't have to define the full key, instead you can pass only the starting part of the key. This means, if you have following caches defined: - news/list/2 - news/list/3 - news/list/4 - news/comments/134 - news/comments/51 you can mark all listing caches as invalid by calling - invalidateCache('news/list'); or mark all caches as invalid which starts with news/ you can call: - invalidateCache('news'); The invalidation mechanism explodes the key by / and checks all levels whether they're marked as invalid (through a microsecond timestamp) or not. Default is $time is mark all caches as invalid which are older than CURRENT. This method is called by the Jarves\Configuration\Event::$clearCaches configuration

public invalidateCache ( string $key, integer $time = null ) : boolean
$key	string
$time	integer	Unix timestamp. Default is microtime(true). Uses float for ms.
Результат	boolean

isCacheIsValid() публичный Метод

Returns an timestamp as integer which tells the cache handler that all stored caches before this timestamp are automatically invalide. Returns null when no invalidation has set yet, means also that the cache with given key is valid.

public isCacheIsValid ( $key, $timestamp ) : integer | null
Результат	integer | null

setDistributedCache() публичный Метод

This stores a ms timestamp on the distributed cache (Jarves::setCache()) and the actual data on the high-speed cache driver (Jarves::setFastCache()). This mechanism makes sure, you gain the maximum performance by using the fast cache driver to store the actual data and using the distributed cache driver to store a ms timestamp where we can check (over several jarves.cms installations) whether the cache is still valid or not. Use Jarves::invalidateCache($key) to invalidate this cache. You don't have to define the full key, instead you can pass only a part of the key.

public setDistributedCache ( string $key, mixed $value, integer $lifeTime = null ) : boolean
$key	string
$value	mixed	Only simple data types. Serialize your value if you have objects/arrays.
$lifeTime	integer
Результат	boolean

setFastCache() публичный Метод

Does not use cache invalidation mechanism. Notes: Not practical for load balances or php-pm scenarios. Not even practical when you use PHP in PHP-FPM, because there are several php instances as well which do nothing know about cache refreshing in this fast cache. Is only useful for configuration purposes at bootstrap or in combination with the invalidation mechanism (which is then the same as if you would call setDistributedCache())

public setFastCache ( string $key, mixed $value, integer $lifeTime = null ) : boolean
$key	string
$value	mixed	Only simple data types. Serialize your value if you have objects/arrays.
$lifeTime	integer
Результат	boolean
