Details

abstract 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

abstract 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

abstract 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

abstract 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

abstract 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

hasItem($key)

{@inheritdoc}

Parameters

$key

clear()

{@inheritdoc}

deleteItem($key)

{@inheritdoc}

Parameters

$key

deleteItems(array $keys)

{@inheritdoc}

Parameters

array $keys

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

reset()

{@inheritdoc}

static protected mixed unserialize(string $value)

Like the native unserialize() function but throws an exception if anything goes wrong.

Parameters

string $value

Return Value

mixed

Exceptions

Exception

static handleUnserializeCallback($class)

Parameters

$class

__construct(Redis|RedisArray|RedisCluster|Client $redisClient, string $namespace = '', int $defaultLifetime = 0)

Parameters

Redis|RedisArray|RedisCluster|Client $redisClient The redis client
string $namespace
int $defaultLifetime

static AdapterInterface createSystemCache(string $namespace, int $defaultLifetime, string $version, string $directory, LoggerInterface $logger = null)

Parameters

string $namespace
int $defaultLifetime
string $version
string $directory
LoggerInterface $logger

Return Value

AdapterInterface

static Redis|Client createConnection(string $dsn, array $options = array())

Creates a Redis connection using a DSN configuration.

Example DSN: - redis://localhost - redis://example.com:1234 - redis://secret@example.com/13 - redis:///var/run/redis.sock - redis://secret@/var/run/redis.sock/13

Parameters
