ObjectIdGenerators.UUIDGenerator (jackson-annotations 2.3.3)

java.lang.Object
- com.fasterxml.jackson.annotation.ObjectIdGenerator<T>
- - com.fasterxml.jackson.annotation.ObjectIdGenerators.UUIDGenerator

All Implemented Interfaces:

Serializable

Enclosing class:

ObjectIdGenerators
```
public static final class ObjectIdGenerators.UUIDGenerator
extends ObjectIdGenerator<T>
```
Implementation that just uses 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.

Method Summary

Methods
Modifier and Type	Method and Description
`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

    Can just return base instance since this is essentially scopeless
    
    Specified by:
    
    forScope in class ObjectIdGenerator<UUID>
  - newForSerialization
```
public ObjectIdGenerator<UUID> newForSerialization(Object context)

    Can just return base instance since this is essentially scopeless
    
    Specified by:
    
    newForSerialization in class ObjectIdGenerator<UUID>
    
    Parameters:
    context - Serialization context object used (of type com.fasterxml.jackson.databind.SerializerProvider; may be needed by more complex generators to access contextual information such as configuration.
  - generateId
```
public UUID generateId(Object forPojo)
```
    Description copied from class: ObjectIdGenerator
    
    Method used for generating a new Object Identifier to serialize for given POJO.
    
    Parameters:
    forPojo - POJO for which identifier is needed
    
    Returns:
    Object Identifier to use.
  - key
```
public ObjectIdGenerator.IdKey key(Object key)
```
    Description copied from class: ObjectIdGenerator
    
    Method for constructing key to use for ObjectId-to-POJO maps.
    
    Specified by:
    
    key in class ObjectIdGenerator<UUID>
  - canUseFor
```
public boolean canUseFor(ObjectIdGenerator<?> gen)
```
    Since UUIDs are always unique, let's fully ignore scope definition
    
    Returns:
    True if this instance can be used as-is; false if not
