Options which modify how this update workflow is performed.
InternalUpdate the source data for a DataModel which includes this DataField. This method is responsible for modifying the provided source data as well as updating the tracked diff included in provided metadata.
Source data of the DataModel which should be updated. This object is always a partial node of source data, relative to which this field belongs.
The name of this field within the context of the source data.
The candidate value that should be applied as an update.
The accumulated diff that is recursively populated as the model traverses through its schema fields.
Options which modify how this update workflow is performed.
InternalCertain fields may declare joint data validation criteria. This method will only be called if the field is designated as recursive.

Apply a function to this DataField which propagates through recursively to any contained data schema.

Apply an ActiveEffectChange to this field.
The field's current value.
The model instance.
The change to apply.
The updated value.
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.

Export the current value of the field into a serializable object.
The initialized value of the field
An exported representation of the field
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), by returning false, or by returning a DataModelValidationFailure instance. A validator which returns true denotes that the result is certainly valid and further validations are unnecessary.
The initial value
Optionaloptions: DataFieldValidationOptions = {}Options which affect validation behavior
Returns a DataModelValidationFailure if a validation failure occurred.
