Methods
__construct()
public
__construct(AdapterInterface $pool) : mixed
Parameters
- $pool : AdapterInterface
Return values
mixed —clear()
Deletes all items in the pool.
public
clear([string $prefix = '' ]) : bool
Parameters
- $prefix : string = ''
Return values
bool —clearCalls()
public
clearCalls() : mixed
Return values
mixed —commit()
{@inheritdoc}
public
commit() : bool
Return values
bool —delete()
Removes an item from the pool.
public
delete(string $key) : bool
Parameters
- $key : string
-
The key to delete
Return values
bool —True if the item was successfully removed, false if there was any error
deleteItem()
{@inheritdoc}
public
deleteItem(mixed $key) : bool
Parameters
- $key : mixed
Return values
bool —deleteItems()
{@inheritdoc}
public
deleteItems(array<string|int, mixed> $keys) : bool
Parameters
- $keys : array<string|int, mixed>
Return values
bool —get()
Fetches a value from the pool or computes it if not found.
public
get(string $key, callable $callback[, float $beta = null ][, array<string|int, mixed> &$metadata = null ]) : mixed
Parameters
- $key : string
-
The key of the item to retrieve from the cache
- $callback : callable
-
Should return the computed value for the given key/item
- $beta : float = null
-
A float that, as it grows, controls the likeliness of triggering early expiration. 0 disables it, INF forces immediate expiration. The default (or providing null) is implementation dependent but should typically be 1.0, which should provide optimal stampede protection. See https://en.wikipedia.org/wiki/Cache_stampede#Probabilistic_early_expiration
- $metadata : array<string|int, mixed> = null
-
The metadata of the cached item ItemInterface::getMetadata()
Return values
mixed —The value corresponding to the provided key
getCalls()
public
getCalls() : mixed
Return values
mixed —getItem()
Returns a Cache Item representing the specified key.
public
getItem(mixed $key) : CacheItem
Parameters
- $key : mixed
-
The key for which to return the corresponding Cache Item.
Return values
CacheItem —getItems()
Returns a traversable set of cache items.
public
getItems([array<string|int, mixed> $keys = [] ]) : Traversable|array<string|int, CacheItem>
Parameters
