Properties

Methods

clear()

Deletes all items in the pool.

public clear([string $prefix = '' ]) : bool
Parameters
$prefix : string = ''
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|null $beta = null ][, array<string|int, mixed>|null &$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 = 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 = null

The metadata of the cached item ItemInterface::getMetadata()

Return values
mixed

getItems()

Returns a traversable set of cache items.

public getItems([array<string|int, mixed> $keys = [] ]) : Traversable<string, CacheItem>
Parameters
$keys : array<string|int, mixed> = []
Return values
Traversable<string, CacheItem>

hasItem()

{@inheritdoc}

public hasItem(mixed $key) : bool
Parameters
$key : mixed
Return values
bool

start()

protected start(string $name) : mixed
Parameters
$name : string
Return values
mixed
