All Implemented Interfaces:

com.vaadin.data.Item, ItemAdapter, JcrItemAdapter, Serializable

Direct Known Subclasses:

JcrNewNodeAdapter

public class JcrNodeAdapter
extends AbstractJcrNodeAdapter

Base implementation of an Item wrapping/representing a Node. Implements Property.ValueChangeListener in order to inform/change JCR property when a Vaadin property has changed.

  

      Jcr properties are read from Repository as long as they are not modified.
  

  Jcr properties are updated or created if they:
  

      
Previously existed and where modified.
      
Newly created and set (an empty created property is not stored into Jcr repository)
  
  

      Create a JcrNodeAdapter:
  

      
Just create a new JcrNodeAdapter with the related Jcr Node as parameter.
  
  

      Properties:
  

      
getItemProperty(Object id) will return the current stored JCR property if not yet modified or the modified one.
      
If the property do not exist null will be returned.
      
In this case we have to create a new Property and attach this property to the JcrNodeAdapter, i.e.
  

  
      property p = DefaultPropertyUtil.newDefaultProperty(...)
      jcrNodeAdapter.addItemProperty(...)
