Modifier and Type | Class and Description |
---|---|
static class |
ObjectIdGenerators.IntSequenceGenerator
Simple sequence-number based generator, which uses basic Java
int s (starting with value 1) as Object Identifiers. |
static class |
ObjectIdGenerators.None
Abstract marker class used to allow explicitly specifying
that no generator is used; which also implies that no
Object Id is to be included or used.
|
static class |
ObjectIdGenerators.PropertyGenerator
Abstract place-holder class which is used to denote case
where Object Identifier to use comes from a POJO property
(getter method or field).
|
static class |
ObjectIdGenerators.StringIdGenerator
Implementation that will accept arbitrary (but unique) String Ids on
deserialization, and (by default) use random UUID generation similar
to
ObjectIdGenerators.UUIDGenerator for generation ids. |
static class |
ObjectIdGenerators.UUIDGenerator
Implementation that just uses
UUID s as reliably
unique identifiers: downside is that resulting String is
36 characters long. |
Modifier and Type | Method and Description |
---|---|
ObjectIdGenerator<Integer> |
ObjectIdGenerators.IntSequenceGenerator.forScope(Class<?> scope) |
ObjectIdGenerator<UUID> |
ObjectIdGenerators.UUIDGenerator.forScope(Class<?> scope)
Can just return base instance since this is essentially scopeless
|
ObjectIdGenerator<String> |
ObjectIdGenerators.StringIdGenerator.forScope(Class<?> scope) |
abstract ObjectIdGenerator<T> |
ObjectIdGenerator.forScope(Class<?> scope)
Factory method to create a blueprint instance for specified
scope.
|
ObjectIdGenerator<Integer> |
ObjectIdGenerators.IntSequenceGenerator.newForSerialization(Object context) |
ObjectIdGenerator<UUID> |
ObjectIdGenerators.UUIDGenerator.newForSerialization(Object context)
Can just return base instance since this is essentially scopeless
|
ObjectIdGenerator<String> |
ObjectIdGenerators.StringIdGenerator.newForSerialization(Object context) |
abstract ObjectIdGenerator<T> |
ObjectIdGenerator.newForSerialization(Object context)
Factory method called to create a new instance to use for
serialization: needed since generators may have state
(next id to produce).
|
Modifier and Type | Method and Description |
---|---|
boolean |
ObjectIdGenerators.UUIDGenerator.canUseFor(ObjectIdGenerator<?> gen)
Since UUIDs are always unique, let's fully ignore scope definition
|
boolean |
ObjectIdGenerators.StringIdGenerator.canUseFor(ObjectIdGenerator<?> gen) |
abstract boolean |
ObjectIdGenerator.canUseFor(ObjectIdGenerator<?> gen)
Method called to check whether this generator instance can
be used for Object Ids of specific generator type and
scope; determination is based by passing a configured
"blueprint" (prototype) instance; from which the actual
instances are created (using
newForSerialization(java.lang.Object) ). |
