> The JCR specification does not support empty properties:
> - only the setProperty() method exists
> - setting a property to null removes it
> But the content API has both createNodeData() and setNodeData() methods but
> since they use JCR properties they behave which I consider being wrong:
> - createNodeData(name) will not fail if a node data already exist
> - setNodeData(name) will not fail it the node data doesn't exist yet
> - getNodeData(name) will never fail but return an nodeData where isExists()
> might return false
> - createNodeData(name, type) creates a property by setting an empty string
> value (null would not create a property) no matter what type you specify
> So there are two solutions possible:
> A) differentiate the creation and setting
> - means throw exception if you are doing wrong
> B) drop the explicit creation (as in JCR)
> I am very much in favor of B) and would like to deprecate all
> createNodeData() methods
