IdentityIF (Ontopia)

All Superinterfaces:

Cloneable

All Known Implementing Classes:

AtomicIdentity, Identity, LongIdentity, WrappedIdentity
```
public interface IdentityIF
extends Cloneable
```
INTERNAL: Interface used to represent data store object identity. The identity has two parts; the type of object and an ordered list of primary key components. Note that an identity instance should always be immutable. Warning: Implementations of this class must all have the same hashCode() behaviour.
