public BaseFieldDefinition::hasCustomStorage() Returns the storage behavior for this field. Indicates whether the entity type's storage should take care of storing the field values or whether it is handled separately; e.g. by the module providing the field. Return value bool FALSE if the storage takes care of storing the field, TRUE otherwise.

public BaseFieldDefinition::getUniqueStorageIdentifier() Returns a unique identifier for the field. Return value string Overrides FieldStorageDefinitionInterface::getUniqueStorageIdentifier File core/lib/Drupal/Core/Field/BaseFieldDefinition.php, line 711 Class BaseFieldDefinition A class for defining entity fields. Namespace Drupal\Core\Field Code public function getUniqueStorageIdentifier() { return $this->getTargetEntityTypeId() . '-' . $this->getName(); }

public BaseFieldDefinition::getType() Returns the field type. Return value string The field type, i.e. the id of a field type plugin. For example 'text'.

Namespace Drupal\Core\Field Code public function getType() { return $this->type; }

public BaseFieldDefinition::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): FieldDefinitionInterface::getTargetEntityTypeId() answers "as a field, which entity type are you attached to?". EntityInterface::getEntityTypeId() answers "as a (config) entity, what is your own entity type?". Return value string

public BaseFieldDefinition::getTargetBundle() Gets the bundle the field is attached to. This method should not be confused with EntityInterface::bundle() (configurable fields are config entities, and thus implement both interfaces): FieldDefinitionInterface::getTargetBundle() answers "as a field, which bundle are you attached to?". EntityInterface::bundle() answers "as a (config) entity, what is your own bundle?" (not relevant in our case, the config entity types used to store the definitions

public BaseFieldDefinition::getSettings() Returns the array of settings, as required by the used class. See the documentation of the class for supported or required settings. Return value array The array of settings.

public BaseFieldDefinition::getSetting($setting_name) Returns the value of a given setting. Parameters string $setting_name: The setting name. Return value mixed The setting value.

public BaseFieldDefinition::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 inte

public BaseFieldDefinition::getProvider() Returns the name of the provider of this field. Return value string The provider name; e.g., the module name. Overrides FieldStorageDefinitionInterface::getProvider File core/lib/Drupal/Core/Field/BaseFieldDefinition.php, line 195 Class BaseFieldDefinition A class for defining entity fields. Namespace Drupal\Core\Field Code public function getProvider() { return isset($this->definition['provider']) ? $this->definition['provider'] : NUL

public BaseFieldDefinition::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.
