Remarks

This method is used for data serialization logic and for field validation logic that is specific to a custom field type.

In a custom type-specific class, override this method to define the following kinds of logic:

• Data-validation; for example, to throw an exception in server-side code if the field is required.

• Pre-update data processing; for example, to filter out bad data but not fail validation.

• Serialization; for example, to convert a field value object into string format.
