Interface Summary

Interface	Description
CopyableValue<T>	Interface to be implemented by basic types that support to be copied efficiently.
Key<T>	This interface has to be implemented by all data types that act as key.
NormalizableKey<T>	The base interface for normalizable keys.
ResettableValue<T extends Value>
Value	Basic value interface for types that act as serializable values.
