Member Function Documentation

static generateSampleValue ( FieldDefinitionInterface  $field_definition)
static

{Generates placeholder field values.Useful when populating site with placeholder content during site building or profiling.

Parameters
\Drupal\Core\Field\FieldDefinitionInterface$field_definitionThe field definition.
Returns
array An associative array of values.
}

Implements FieldItemInterface.

Referenced by EntityUser\processStubRow().

Here is the caller graph for this function:

getConstraints ( )

{Gets a list of validation constraints.

Returns
array Array of constraints, each being an instance of .
}

Implements TypedDataInterface.

References FieldItemBase\getFieldDefinition(), t(), and Drupal\typedDataManager().

Here is the call graph for this function:

isEmpty ( )

{Determines whether the data structure is empty.

Returns
bool TRUE if the data structure is empty, FALSE otherwise.
}

Implements ComplexDataInterface.

static propertyDefinitions ( FieldStorageDefinitionInterface  $field_definition)
static

{Defines field item properties.Properties that are required to constitute a valid, non-empty item should be denoted with ::setRequired().

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

}

Implements FieldItemInterface.

References DataDefinition\create(), and t().

Here is the call graph for this function:

static schema ( FieldStorageDefinitionInterface  $field_definition)
static

{Returns the schema for the field.This method is static because the field schema information is needed on creation of the field. FieldItemInterface objects instantiated at that time are not reliable as field settings might be missing.Computed fields having no schema should return an empty array.

Parameters
\Drupal\Core\Field\FieldStorageDefinitionInterface$field_definitionThe field definition.
Returns
array An empty array if there is no schema, or an associative array with the following key/value pairs:
  • columns: An array of Schema API column specifications, keyed by column name. The columns need to be a subset of the properties defined in propertyDefinitions(). The 'not null' property is ignored if present, as it is determined automatically by the storage controller depending on the table layout and the property definitions. It is recommended to avoid having the column definitions depend on field settings when possible. No assumptions should be made on how storage engines internally use the original column name to structure their storage.
  • unique keys: (optional) An array of Schema API unique key definitions. Only columns that appear in the 'columns' array are allowed.
  • indexes: (optional) An array of Schema API index definitions. Only columns that appear in the 'columns' array are allowed. Those indexes will be used as default indexes. Field definitions can specify additional indexes or, at their own risk, modify the default indexes specified by the field-type module. Some storage engines might not support indexes.
  • foreign keys: (optional) An array of Schema API foreign key definitions. Note, however, that the field data is not necessarily stored in SQL. Also, the possible usage is limited, as you cannot specify another field as related, only existing SQL tables, such as {taxonomy_term_data}.
}
