implements CRM_Utils_Cache_Interface uses CRM_Utils_Cache_NaiveMultipleTrait

Class CRM_Utils_Cache_ArrayDecorator

This creates a two-tier cache-hierarchy: a thread-local, array-based cache combined with some third-party cache driver.

Ex: $cache = new CRM_Utils_Cache_ArrayDecorator(new CRM_Utils_Cache_Redis(...));

Properties

$defaultTimeout

protected int $defaultTimeout

Default time-to-live (seconds) for cache items that don't have a TTL.

$expires

private array<string|int, mixed> $expires = []

Array(string $cacheKey => int $expirationTime).

$values

private array<string|int, mixed> $values = []

Array(string $cacheKey => mixed $cacheValue).

Methods

clear()

Delete all values from the cache.

public clear() : bool

NOTE: flush() and clear() should be aliases. flush() is specified by Civi's traditional interface, and clear() is specified by PSR-16.

Return values
bool

delete()

Delete a value from the cache.

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

deleteMultiple()

Deletes multiple cache items in a single operation.

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

A list of string-based keys to be deleted.

Tags
throws
InvalidArgumentException

MUST be thrown if $keys is neither an array nor a Traversable, or if any of the $keys are not a legal value.

Return values
bool —

True if the items were successfully removed. False if there was an error.

flush()

Delete all values from the cache.

public flush() : bool

NOTE: flush() and clear() should be aliases. flush() is specified by Civi's traditional interface, and clear() is specified by PSR-16.

Return values
bool

get()

Get a value from the cache.

public get(mixed $key[, mixed $default = NULL ]) : mixed
Parameters
$key : mixed
$default : mixed = NULL
Return values
mixed —

The previously set value value, or $default (NULL).

getMultiple()

Obtains multiple cache items by their unique keys.

public getMultiple(iterable<string|int, mixed> $keys[, mixed $default = NULL ]) : iterable<string|int, mixed>
Parameters
$keys : iterable<string|int, mixed>

A list of keys that can obtained in a single operation.

$default : mixed = NULL

Default value to return for keys that do not exist.

Tags
throws
InvalidArgumentException

MUST be thrown if $keys is neither an array nor a Traversable, or if any of the $keys are not a legal value.

Return values
iterable<string|int, mixed> —

A list of key => value pairs. Cache keys that do not exist or are stale will have $default as value.

has()

Determines whether an item is present in the cache.

public has(mixed $key) : bool

NOTE: It is recommended that has() is only to be used for cache warming type purposes and not to be used within your live applications operations for get/set, as this method is subject to a race condition where your has() will return true and immediately after, another script can remove it making the state of your app out of date.

Parameters
$key : mixed

The cache item key.

Return values
bool

set()

Set the value in the cache.

public set(mixed $key, mixed $value[, mixed $ttl = NULL ]) : bool
Parameters
$key : mixed
$value : mixed
$ttl : mixed = NULL
Return values
bool

setMultiple()

Persists a set of key => value pairs in the cache, with an optional TTL.

public setMultiple(iterable<string|int, mixed> $values[, null|int|DateInterval $ttl = NULL ]) : bool
Parameters
$values : iterable<string|int, mixed>

A list of key => value pairs for a multiple-set operation.

$ttl : null|int|DateInterval = NULL

Optional. The TTL value of this item. If no value is sent and the driver supports TTL then the library may set a default value for it or let the driver take care of that.

Tags
throws
InvalidArgumentException

MUST be thrown if $values is neither an array nor a Traversable, or if any of the $values are not a legal value.

Return values
bool —

True on success and false on failure.

reobjectify()

private reobjectify(mixed $value) : mixed
Parameters
$value : mixed
