A DataField instance which defines the type of element contained in the Array.
Options which configure the behavior of the field
The data type of each element in this array
The initially provided options which configure the data field
The field name of this DataField instance. This is assigned by SchemaField#initialize.
A reference to the parent schema to which this DataField belongs. This is assigned by SchemaField#initialize.
Coerce source data to ensure that it conforms to the correct data type for the field. Data coercion operations should be simple and synchronous as these are applied whenever a DataModel is constructed. For one-off cleaning of user-provided input the sanitize method should be used.
The initial value
The cast value
Attempt to retrieve a valid initial value for the DataField.
The source data object for which an initial value is required
A valid initial value
Validate a candidate input for this field, ensuring it meets the field requirements. A validation failure can be provided as a raised Error (with a string message) or by returning false. A validator which returns true denotes that the result is certainly valid and further validations are unnecessary.
The initial value
Returns a ModelValidationError if a validation failure occurred
Validate every element of the ArrayField
The array to validate
Validation options
An array of element-specific errors
Special validation rules which supersede regular field validation. This validator screens for certain values which are otherwise incompatible with this field like null or undefined.
The candidate value
A boolean to indicate with certainty whether the value is valid. Otherwise, return void.
Validate the contained element type of the ArrayField
The type of Array element
The validated element type
A dot-separated string representation of the field path within the parent schema.
A subclass of DataField which deals with array-typed data.
