Class UniqueId

java.lang.Object

tools.jackson.databind.util.UniqueId

All Implemented Interfaces:

Serializable, Comparable<UniqueId>

public class UniqueId
extends Object
implements Serializable, Comparable<UniqueId>

Simple identity value class that may be used as Serializable key for entries that need to retain identity of some kind, but where actual appearance of id itself does not matter. Instances NEVER equal each other, only themselves, even if generated ids might be same (although they should not be).

Since:

3.0
