Interface CanonicalValue<T extends CanonicalValue<T>>

Type Parameters:

T - Canonical value type

All Superinterfaces:

Comparable<T>, Immutable, MutationBehaviour<Immutable>, Serializable

All Known Implementing Classes:

CachingDerivedString, Decimal64, DerivedString, Uint16, Uint32, Uint64, Uint8

@Beta
 @NonNullByDefault
public interface CanonicalValue<T extends CanonicalValue<T>>
extends Comparable<T>, Immutable, Serializable

A typed value in its internal Java representation. Implementations of this interface are required to:

• be immutable
• be Serializable
• accurately define total ordering of values

Aside from providing the ability to hold a canonical value, this interface and its implementations support carrying additional information about how the value has been validated -- allowing efficient interchange of already-validated values between users. validator() provides the link to a CanonicalValueValidator which has declared the value conform to it. Users can query the validator to establish whether the value needs to be further validated to conform to their requirement.
