Properties

Methods

clear()

Deletes all items in the pool.

public clear([string $prefix = '' ]) : bool
Parameters
$prefix : string = ''
Return values
bool —

commit()

{@inheritdoc}

public commit() : bool
Return values
bool —

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

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.

$keys : array<string|int, mixed> = []

An indexed array of keys of items to retrieve.

Return values
Traversable|array<string|int, CacheItem> —

hasItem()
