[jira] Created: (GRFT-126) Add support for the "Reference" jcr type

Add support for the "Reference" jcr type
----------------------------------------

                 Key: GRFT-126
                 URL: https://issues.apache.org/jira/browse/GRFT-126
             Project: Graffito
          Issue Type: Sub-task
            Reporter: Christophe Lombart


Supporting reference could be done in different ways.

Just a couple of ideas (which required more investigation ) :

* Define a field-descriptor which will contain an uuid to point to another object.
* Define a bean descriptor which is mapped to a jcr prop of type reference.
* Define a collection of properties based on the type "Reference".
* Define a collection containing some referenced beans.

Christophe Lombart commented on GRFT-126:
-----------------------------------------

I just commited the following point :

* There is a new atomic converter (ReferenceTypeConverterImpl) which can be used to map a String attribute into a jcr property (based on the reference type).
   ex. :  
                <field-descriptor fieldName="reference2A" jcrName="reference2A" converter="org.apache.portals.graffito.jcr.persistence.atomictypeconverter.impl.ReferenceTypeConverterImpl" />

  in this example, the jcr prop "reference2A" will contains a valid uuid.


* There is a new bean converter (ReferenceBeanConverterImpl) which can be used to map a bean attribute into a jcr reference property.

ex.:
                <bean-descriptor fieldName="a" jcrName="a" converter="org.apache.portals.graffito.jcr.persistence.beanconverter.impl.ReferenceBeanConverterImpl" />

In this example, the jcr prop "a'" will contain a valid uuid but in the java object graph, the object matching to this uuid will be loaded.

* See the unit test : PersistenceManagerUuidTest to get more details.

I'm going to work on uuid/reference support in collections.

Christophe Lombart resolved GRFT-126.
-------------------------------------

       Resolution: Fixed
    Fix Version/s: ocm-1.0

Add new collection converters used to support the following cases :

* Define a collection of properties based on the type "Reference".
* Define a collection containing some referenced beans.

Review unit tests.
