$this setSyncing(bool $status)

Sets the status of the synchronization flag.

Parameters

bool $status

The status of the synchronization flag.

Return Value

$this

bool isSyncing()

Returns whether this entity is being changed as part of a synchronization.

If you are writing code that responds to a change in this entity (insert, update, delete, presave, etc.), and your code would result in a change to this entity itself, a configuration change (whether related to this entity, another entity, or non-entity configuration), you need to check and see if this entity change is part of a synchronization process, and skip executing your code if that is the case.

For example, \Drupal\node\Entity\NodeType::postSave() adds the default body field to newly created node type configuration entities, which is a configuration change. You would not want this code to run during an import, because imported entities were already given the body field when they were originally created, and the imported configuration includes all of their currently-configured fields. On the other hand, \Drupal\field\Entity\FieldStorageConfig::preSave() and the methods it calls make sure that the storage tables are created or updated for the field storage configuration entity, which is not a configuration change, and it must be done whether due to an import or not. So, the first method should check $entity->isSyncing() and skip executing if it returns TRUE, and the second should not perform this check.

Return Value

bool

TRUE if the configuration entity is being created, updated, or deleted through a synchronization process.

$this enable()

Enables the configuration entity.

Return Value

$this

$this disable()

Disables the configuration entity.

Return Value

$this

$this setStatus(bool $status)

Sets the status of the configuration entity.

Parameters

bool $status

The status of the configuration entity.

Return Value

$this

bool status()

Returns whether the configuration entity is enabled.

Status implementations for configuration entities should follow these general rules:

  • Status does not affect the loading of entities. I.e. Disabling configuration entities should only have UI/access implications.
  • It should only take effect when a 'status' key is explicitly declared in the entity_keys info of a configuration entity's annotation data.
  • Each entity implementation (entity/controller) is responsible for checking and managing the status.

Return Value

bool

Whether the entity is enabled or not.

bool isUninstalling()

Returns whether this entity is being changed during the uninstall process.

If you are writing code that responds to a change in this entity (insert, update, delete, presave, etc.), and your code would result in a configuration change (whether related to this configuration entity, another configuration entity, or non-entity configuration) or your code would result in a change to this entity itself, you need to check and see if this entity change is part of an uninstall process, and skip executing your code if that is the case.

For example, \Drupal\language\Entity\ConfigurableLanguage::preDelete() prevents the API from deleting the default language. However during an uninstall of the language module it is expected that the default language should be deleted.

Return Value

bool

mixed get(string $property_name)

Returns the value of a property.

Parameters

string $property_name

The name of the property that should be returned.

Return Value

mixed

The property if it exists, or NULL otherwise.

$this set(string $property_name, mixed $value)

Sets the value of a property.

Parameters

string $property_name

The name of the property that should be set.

mixed $value

The value the property should be set to.

Return Value

$this

$this calculateDependencies()

Calculates dependencies and stores them in the dependency property.

Return Value

$this

See also

ConfigDependencyManager

bool onDependencyRemoval(array $dependencies)

Informs the entity that entities it depends on will be deleted.

This method allows configuration entities to remove dependencies instead of being deleted themselves. Configuration entities can use this method to avoid being unnecessarily deleted during an extension uninstallation. For example, entity displays remove references to widgets and formatters if the plugin that supplies them depends on a module that is being uninstalled.

If this method returns TRUE then the entity needs to be re-saved by the caller for the changes to take effect. Implementations should not save the entity.

Parameters

array $dependencies

An array of dependencies that will be deleted keyed by dependency type. Dependency types are, for example, entity, module and theme.

Return Value

bool

TRUE if the entity has been changed as a result, FALSE if not.

See also

ConfigDependencyManager
\Drupal\Core\Config\ConfigEntityBase::preDelete()
ConfigManager::uninstall
EntityDisplayBase::onDependencyRemoval

array getDependencies()

Gets the configuration dependencies.

Return Value

array

An array of dependencies, keyed by $type.

See also

ConfigDependencyManager

bool isInstallable()

Checks whether this entity is installable.

For example, a default view might not be installable if the base table doesn't exist.

Return Value

bool

TRUE if the entity is installable, FALSE otherwise.

$this trustData()

Sets that the data should be trusted.

If the data is trusted then dependencies will not be calculated on save and schema will not be used to cast the values. Generally this is only used during module and theme installation. Once the config entity has been saved the data will no longer be marked as trusted. This is an optimization for creation of configuration during installation.

Return Value

$this

See also

ConfigInstaller::createConfiguration

bool hasTrustedData()

Gets whether on not the data is trusted.

Return Value

bool

TRUE if the configuration data is trusted, FALSE if not.

string getName()

Returns the machine name of the field.

This defines how the field data is accessed from the entity. For example, if the field name is "foo", then $entity->foo returns its data.

Return Value

string

The field name.

string getType()

Returns the field type.

Return Value

string

The field type, i.e. the id of a field type plugin. For example 'text'.

array getSettings()

Returns the storage settings.

Each field type defines the settings that are meaningful for that type. For example, a text field can define a 'max_length' setting, and an image field can define an 'alt_field_required' setting.

The method always returns an array of all available settings for this field type, possibly with the default values merged in if values have not been provided for all available settings.

Return Value

array

An array of key/value pairs.

mixed getSetting(string $setting_name)

Returns the value of a given storage setting.

Parameters

string $setting_name

The setting name.

Return Value

mixed

The setting value.

bool isTranslatable()

Returns whether the field supports translation.

Return Value

bool

TRUE if the field supports translation.

Sets whether the field is translatable.

Parameters

bool $translatable

Whether the field supports translation.

Return Value

$this

bool isRevisionable()

Return Value

bool

TRUE if the field is revisionable.

string getLabel()

Returns the human-readable label for the field.

Return Value

string

The field label.

string|null getDescription()

Returns the human-readable description for the field.

This is displayed in addition to the label in places where additional descriptive information is helpful. For example, as help text below the form element in entity edit forms.

Return Value

string|null

The field description, or NULL if no description is available.

OptionsProviderInterface|null getOptionsProvider(string $property_name, FieldableEntityInterface $entity)

Gets an options provider for the given field item property.

Parameters

string $property_name

The name of the property to get options for; e.g., 'value'.

FieldableEntityInterface $entity

The entity for which the options should be provided.

Return Value

OptionsProviderInterface|null

An options provider, or NULL if no options are defined.

bool isMultiple()

Returns whether the field can contain multiple items.

Return Value

bool

TRUE if the field can contain multiple items, FALSE otherwise.

int getCardinality()

Returns the maximum number of items allowed for the field.

Possible values are positive integers or FieldStorageDefinitionInterface::CARDINALITY_UNLIMITED.

int

The field cardinality.

DataDefinitionInterface|null getPropertyDefinition(string $name)

Gets the definition of a contained property.

Parameters

string $name

The name of property.

Return Value

DataDefinitionInterface|null

The definition of the property or NULL if the property does not exist.

DataDefinitionInterface[] getPropertyDefinitions()

Gets an array of property definitions of contained properties.

Return Value

DataDefinitionInterface[]

An array of property definitions of contained properties, keyed by property name.

string[] getPropertyNames()

Returns the names of the field's subproperties.

A field is a list of items, and each item can contain one or more properties. All items for a given field contain the same property names, but the values can be different for each item.

For example, an email field might just contain a single 'value' property, while a link field might contain 'title' and 'url' properties, and a text field might contain 'value', 'summary', and 'format' properties.

Return Value

string[]

The property names.

string|null getMainPropertyName()

Returns the name of the main property, if any.

Some field items consist mainly of one main property, e.g. the value of a text field or the @code target_id @endcode of an entity reference. If the field item has no main property, the method returns NULL.

Return Value

string|null

The name of the value property, or NULL if there is none.

string getTargetEntityTypeId()

Returns the ID of the entity type the field is attached to.

This method should not be confused with EntityInterface::getEntityTypeId() (configurable fields are config entities, and thus implement both interfaces):

  • FieldStorageDefinitionInterface::getTargetEntityTypeId() answers "as a field storage, which entity type are you attached to?".
  • EntityInterface::getEntityTypeId() answers "as a (config) entity, what is your own entity type?".

Return Value

string

The entity type ID.

array[] getSchema()

Returns the field schema.

Note that this method returns an empty array for computed fields which have no schema.

Return Value

array[]

The field schema, as an array of key/value pairs in the format returned by \Drupal\Core\Field\FieldItemInterface::schema():

  • columns: An array of Schema API column specifications, keyed by column name. This specifies what comprises a single value for a given field. No assumptions should be made on how storage backends internally use the original column name to structure their storage.
  • indexes: An array of Schema API index definitions. Some storage backends might not support indexes.
  • unique keys: An array of Schema API unique key definitions. Some storage backends might not support unique keys.
  • foreign keys: An array of Schema API foreign key definitions. Note, however, that depending on the storage backend specified for the field, the field data is not necessarily stored in SQL.

array[] getColumns()

Returns the field columns, as defined in the field schema.

Return Value

array[]

The array of field columns, keyed by column name, in the same format returned by getSchema().
