Description copied from interface: Content

Creates a property and set its value immediately, according to the type of the passed instance, hiding the complexity of using JCR's ValueFactory and providing a sensible default behavior.

Specified by:

createNodeData in interface Content

Throws:

javax.jcr.RepositoryException

getNodeData

public NodeData getNodeData(String name)

Returns a NodeData object. If the node data does not exist (respectively if it has no value) an empty representation is returned whose NodeData.isExist() will return false. Delegates to newNodeDataInstance(String, int, boolean) by setting the type to PropertyType.UNDEFINED. A subclass has to handle this by trying to determine the type if the node data exists. The reason for this is that implementations want to instantiate different node data classes per type

Specified by:

getNodeData in interface Content

Returns:

NodeData requested NodeData object

newNodeDataInstance

                                             javax.jcr.RepositoryException

As defined in Content.getNodeData(String) this method always returns a node data object. If the type is PropertyType.UNDEFINED the implementation should check if the node data exists and determine the type to use.

Parameters:

createIfNotExisting - if false an empty non-mutable node data will be returned if the node data doesn't exist otherwise a mutable nodedata object is returned (depending on the type)

Throws:

AccessDeniedException

javax.jcr.RepositoryException

hasNodeData

public boolean hasNodeData(String name)
                    throws javax.jcr.RepositoryException

Delegates to NodeData.isExist().

Specified by:

hasNodeData in interface Content

Throws:

javax.jcr.RepositoryException - if an error occurs
