DOCTRINE_NAMESPACE_CACHEKEY

public mixed DOCTRINE_NAMESPACE_CACHEKEY = 'DoctrineNamespaceCacheKey[%s]'

Properties

$namespace

The namespace to prefix all cache ids with.

private string $namespace = ''

$namespaceVersion

The namespace version.

private int|null $namespaceVersion

Methods

contains()

Tests if an entry exists in the cache.

public contains(mixed $id) : bool
Parameters
$id : mixed

The cache id of the entry to check for.

Return values
bool —

TRUE if a cache entry exists for the given cache id, FALSE otherwise.

delete()

Deletes a cache entry.

public delete(mixed $id) : bool
Parameters
$id : mixed

The cache id.

Return values
bool —

TRUE if the cache entry was successfully deleted, FALSE otherwise. Deleting a non-existing entry is considered successful.

deleteAll()

Deletes all cache entries in the current cache namespace.

public deleteAll() : bool
Return values
bool —

TRUE if the cache entries were successfully deleted, FALSE otherwise.

deleteMultiple()

{@inheritdoc}

public deleteMultiple(array<string|int, mixed> $keys) : mixed
Parameters
$keys : array<string|int, mixed>

fetch()

Fetches an entry from the cache.

public fetch(mixed $id) : mixed
Parameters
$id : mixed

The id of the cache entry to fetch.

Return values
mixed —

The cached data or FALSE, if no cache entry exists for the given id.

fetchMultiple()

{@inheritdoc}

public fetchMultiple(array<string|int, mixed> $keys) : mixed
Parameters
$keys : array<string|int, mixed>

flushAll()

Flushes all cache entries, globally.

public flushAll() : bool
Return values
bool —

TRUE if the cache entries were successfully flushed, FALSE otherwise.

getNamespace()

Retrieves the namespace that prefixes all cache ids.

public getNamespace() : string
Return values
string

getStats()

Retrieves cached information from the data store.

public getStats() : array<string|int, mixed>|null
Return values
array<string|int, mixed>|null —

An associative array with server's statistics if available, NULL otherwise.

save()

Puts data into the cache.

public save(mixed $id, mixed $data[, mixed $lifeTime = 0 ]) : bool
Parameters
$id : mixed

The cache id.

$data : mixed

The cache entry/data.

$lifeTime : mixed = 0

The lifetime in number of seconds for this cache entry. If zero (the default), the entry never expires (although it may be deleted from the cache to make place for other entries).

Return values
bool —

TRUE if the entry was successfully stored in the cache, FALSE otherwise.

saveMultiple()

{@inheritdoc}

public saveMultiple(array<string|int, mixed> $keysAndValues[, mixed $lifetime = 0 ]) : mixed
Parameters
$keysAndValues : array<string|int, mixed>
$lifetime : mixed = 0

setNamespace()

bool

doDelete()

Deletes a cache entry.

protected doDelete(mixed $id) : bool
Parameters
$id : mixed

The id of the cache entry to fetch.

Return values
mixed|false —

The cached data or FALSE, if no cache entry exists for the given id.

doFetchMultiple()

Default implementation of doFetchMultiple. Each driver that supports multi-get should owerwrite it.

protected doFetchMultiple(array<string|int, string> $keys) : array<string|int, mixed>
Parameters
$keys : array<string|int, string>

Array of keys to retrieve from cache
