abstract
getDefinitions()
{@inheritdoc}
getDefinition($plugin_id, $exception_on_invalid = TRUE)
{@inheritdoc}
protected array|null
doGetDefinition(array $definitions, string $plugin_id, bool $exception_on_invalid)
Gets a specific plugin definition.
hasDefinition($plugin_id)
{@inheritdoc}
protected DiscoveryInterface
getDiscovery()
Gets the plugin discovery.
protected FactoryInterface
getFactory()
Gets the plugin factory.
object
createInstance(string $plugin_id, array $configuration = [], ImageToolkitInterface $toolkit = NULL)
Creates a pre-configured instance of a plugin.
protected object
handlePluginNotFound(string $plugin_id, array $configuration)
Allows plugin managers to specify custom behavior if a plugin is not found.
object|false
getInstance(array $options)
Gets a preconfigured instance of a plugin.
protected object|false
cacheGet(string $cid)
Fetches from the cache backend, respecting the use caches flag.
protected
cacheSet(string $cid, mixed $data, int $expire = Cache::PERMANENT, array $tags = [])
Stores data in the persistent cache, respecting the use caches flag.
__construct(Traversable $namespaces, CacheBackendInterface $cache_backend, ModuleHandlerInterface $module_handler, LoggerInterface $logger, ImageToolkitManager $toolkit_manager)
Constructs the ImageToolkitOperationManager object.
setCacheBackend(CacheBackendInterface $cache_backend, string $cache_key, array $cache_tags = [])
Initialize the cache backend.
Plugin definitions are cached using the provided cache backend.
protected
alterInfo(string $alter_hook)
Sets the alter hook name.
clearCachedDefinitions()
Clears static and persistent plugin definition caches.
Don't resort to calling \Drupal::cache()->delete() and friends to make Drupal detect new or updated plugin definitions. Always use this method on the appropriate plugin type's plugin manager!
protected array|null
getCachedDefinitions()
Returns the cached plugin definitions of the decorated discovery class.
protected
setCachedDefinitions(array $definitions)
Sets a cache of plugin definitions for the decorated discovery class.
useCaches(bool $use_caches = FALSE)
Disable the use of caches.
Can be used to ensure that uncached plugin definitions are returned, without invalidating all cached information.
This will also remove all local/static caches.
processDefinition($definition, $plugin_id)
Performs extra processing on plugin definitions.
By default we add defaults for the type to the definition. If a type has additional processing logic they can do that by replacing or extending the method.
protected array
findDefinitions()
Finds plugin definitions.
protected string|null
extractProviderFromDefinition(mixed $plugin_definition)
Extracts the provider from a plugin definition.
protected
alterDefinitions($definitions)
Invokes the hook to alter the definitions if the alter hook is set.
protected bool
providerExists($provider)
Determines if the provider of a definition exists.
string[]
getCacheContexts()
The cache contexts associated with this object.
These identify a specific variation/representation of the object.
Cache contexts are tokens: placeholders that are converted to cache keys by the @cache_contexts_manager service. The replacement value depends on the request context (the current URL, language, and so on). They're converted before storing an object in cache.
string[]
getCacheTags()
The cache tags associated with this object.
When this object is modified, these cache tags will be invalidated.
int
getCacheMaxAge()
The maximum age for which this object may be cached.
protected string
getToolkitOperationPluginId(ImageToolkitInterface $toolkit, string $operation)
Returns the plugin ID for a given toolkit and operation.
ImageToolkitOperationInterface
getToolkitOperation(ImageToolkitInterface $toolkit, string $operation)
Returns a toolkit operation plugin instance.
