public static final class ObjectIdGenerators.UUIDGenerator extends ObjectIdGenerator<T>
UUIDs as reliably
unique identifiers: downside is that resulting String is
36 characters long.
One difference to other generators is that scope is always
set as Object.class (regardless of arguments): this
because UUIDs are globally unique, and scope has no meaning.

|---|---|
boolean |
canUseFor(ObjectIdGenerator<?> gen)
Since UUIDs are always unique, let's fully ignore scope definition
|
ObjectIdGenerator<UUID> |
forScope(Class<?> scope)
Can just return base instance since this is essentially scopeless
|
UUID |
generateId(Object forPojo)
Method used for generating a new Object Identifier to serialize
for given POJO.
|
ObjectIdGenerator.IdKey |
key(Object key)
Method for constructing key to use for ObjectId-to-POJO maps.
|
ObjectIdGenerator<UUID> |
newForSerialization(Object context)
Can just return base instance since this is essentially scopeless
