Subject [jira] Commented: (GRFT-125) Add UUID support
Date Wed, 07 Mar 2007 21:25:24 GMT

    [ https://issues.apache.org/jira/browse/GRFT-125?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12478902
] 

Christophe Lombart commented on GRFT-125:
-----------------------------------------

I just committed some changes : 

1/ add a new method in the persistence manager : getObjectByUuid(String uuid)
2/ In order to map a bean field into the node uuid, it is possible to add the following field-descriptor
in any class-descriptor : 
<field-descriptor fieldName="myUuid" uudi="true" /> 
notes : path is still mandatory in each class descriptor, otherwise we have to review the
PersistenceManager API (add in almost all public methods a new arg : String path). the uuid
field is optional.
3/ the uuid can be defined in an ancestor class.

> Until now, only the path was used to retrieve content and makes references. Of course,
in some situation UUID becomes more important. Furthermore supporting uuid is mandatory if
we want to support "reference" jcr type. 
> Here is a proposal to support UUID : 
> 1/ Modify the PersistenceManager API : 
>       * add method getObject(String uuid)
>       * Is it necessary to overload methods used to manage versions and locks ? 
> 2/ Review the mapping descriptor in order to map a pojo attribute into the node UUID
(readonly) : 
>       <field-descriptor fieldName="myUuid" uudi="true" />
>       From now, it is possible to specify the path attribute and/or the uuid attribute
in the java classes. Both fields are optional. 
>      So, we have to review the classes PersistenceManagerImpl and ObjectConverterImpl
which depend strongly on the path attribute.
> 3/ Specify in a class-descriptor the jcr type "mix:referenceable ". This can be done
with one of the following way : 
>        a. In the class descriptor definition : 
>                 <class-descriptor  className="...." jcrNodeType="..." jcrMixinTypes="mix:referencable"
>
>        b. or in the primary node type definition associated to the java class
> 4/ It should possible to defined the uuid field in an ancestor class descrptor (similar
to the path field descriptor)
