atomize
in interfaceSchemaType

returned by this SequenceIterator will all be of type
AtomicValue
- Throws:
ValidationException
- This method should be called only if it is known that the value is valid. If the value is not valid, there is no guarantee that this method will perform validation, but if it does detect a validity error, then it MAY throw a ValidationException.
-
equals
Two types are equal if they have the same fingerprint. Note: it is normally safe to use ==, because we always use the static constants, one instance for each built in atomic type. However, after serialization and deserialization a different instance can appear. -
