Details

protected object|false cacheGet(string $cid)

Fetches from the cache backend, respecting the use caches flag.

Parameters

string $cid

The cache ID of the data to retrieve.

Return Value

object|false

The cache item or FALSE on failure.

CacheBackendInterface::get

in UseCacheBackendTrait at line 69
protected cacheSet(string $cid, mixed $data, int $expire = Cache::PERMANENT, array $tags = [])

Stores data in the persistent cache, respecting the use caches flag.

Parameters

string $cid

The cache ID of the data to store.
mixed $data

The data to store in the cache. Some storage engines only allow objects up to a maximum of 1MB in size to be stored by default. When caching large arrays or similar, take care to ensure $data does not exceed this size.
int $expire

One of the following values:

  • CacheBackendInterface::CACHE_PERMANENT: Indicates that the item should not be removed unless it is deleted explicitly.
  • A Unix timestamp: Indicates that the item will be considered invalid after this time, i.e. it will not be returned by get() unless $allow_invalid has been set to TRUE. When the item has expired, it may be permanently deleted by the garbage collector at any time.
array $tags

An array of tags to be stored with the cache item. These should normally identify objects used to build the cache item, which should trigger cache invalidation when updated. For example if a cached item represents a node, both the node ID and the author's user ID might be passed in as tags. For example array('node' => array(123), 'user' => array(92)).

Parameters

string $string

A string containing the English text to translate.

array $options

(optional) An associative array of additional options, with the following elements:

  • 'langcode' (defaults to the current language): A language code, to translate to a language other than what is used to display the page.
  • 'context' (defaults to the empty context): The context the source string belongs to. See the @link i18n Internationalization topic @endlink for more information about string contexts.

Return Value

TranslatableMarkup

An object that, when cast to a string, returns the translated string.

FieldDefinitionInterface[] getBaseFieldDefinitions(string $entity_type_id)

Return Value

FieldDefinitionInterface[]

The array of base field definitions for the entity type, keyed by field name.
