Class NonExistingNodeData

  info.magnolia.cms.core.AbstractNodeData
      info.magnolia.cms.core.NonExistingNodeData

All Implemented Interfaces:

NodeData, Cloneable

public class NonExistingNodeData
extends AbstractNodeData

Represents an non-mutable empty node data. This is returned by Content.getNodeData(String) in case the node data does not exist. This is the case because jcr doesn't support empty properties. All reading methods will return a default value which might be null in some cases. All writing methods will throw an ItemNotFoundException.
