Interface Freezable

All Known Implementing Classes:
Binary, Date, Time, Timestamp
public interface Freezable
A freezable object.

Some classes are value objects by nature, but are not immutable, for example Date.
Whenever the use case requires immutability, such objects cannot be used safely.
That's why Tentackle provides extended implementations of those types, that can be made immutable.

Once an object is frozen, it cannot be unfrozen anymore. However, its clones are unfrozen (if cloneable).
Any attempt to modify a frozen object results in a TentackleRuntimeException.
