Details

at line 39
protected array|Traversable doFetch(array $ids)

Fetches several cache items.

Parameters

array $ids The cache identifiers to fetch

Return Value

array|Traversable The corresponding values found in the cache

at line 51
protected bool doHave(string $id)

Confirms if the cache contains specified cache item.

Parameters

string $id The identifier for which to check existence

Return Value

bool True if item exists in the cache, false otherwise

at line 59
protected bool doClear(string $namespace)

Deletes all items in the pool.

Parameters

string $namespace The prefix used for all identifiers managed by this pool

Return Value

bool True if the pool was successfully cleared, false otherwise

at line 67
protected bool doDelete(array $ids)

Removes multiple items from the pool.

Parameters

array $ids An array of identifiers that should be removed from the pool

Return Value

bool True if the items were successfully removed, false otherwise

at line 75
protected array|bool doSave(array $values, int $lifetime)

Persists several cache items immediately.

Parameters

array $values The values to cache, indexed by their cache identifier
int $lifetime The lifetime of the cached values, 0 for persisting until manual cleaning

Return Value

array|bool The identifiers that failed to be cached or a boolean stating if caching succeeded or not

Parameters

$key

deleteItem($key)

{@inheritdoc}

Parameters

$key

deleteItems(array $keys)

{@inheritdoc}

Parameters

array $keys

in AbstractTrait at line 186
bool enableVersioning(bool $enable = true)

Enables/disables versioning of items.

When versioning is enabled, clearing the cache is atomic and doesn't require listing existing keys to proceed, but old keys may need garbage collection and extra round-trips to the back-end are required.

Calling this method also clears the memoized namespace version and thus forces a resynchonization of it.

Parameters

bool $enable

Return Value

bool the previous state of versioning

static protected mixed unserialize(string $value)
