public final class NodeHelper
extends Object

Provides helper methods on nodes.

Method Summary

Modifier and Type	Method	Description
static String	getFullHashPath(String name)	Get the path with hashed nodes.
static javax.jcr.Node	getOrCreateFinalHashNode(javax.jcr.Node parentNode, String name)	Get or create hash nodes for the given name, intermediate nodes are of type "ametys:collectionElement".
static javax.jcr.Node	getOrCreateFinalHashNode(javax.jcr.Node parentNode, String name, String hashType)	Get or create hash nodes for the given name and intermediate primary type.
static List<String>	hashAsList(String name)	Computes a hashed path in the JCR tree from the name of the child object. Subclasses may override this method to provide a more suitable hash function. This implementation relies on the buzhash algorithm.
static void	rename(javax.jcr.Node node, String newName)	Rename the given Node with the given new name

Method Details

rename

public static void rename(javax.jcr.Node node,
 String newName)
                   throws AmetysRepositoryException

Rename the given Node with the given new name

Parameters:

node - the node to rename

newName - the new name of the node

Throws:

AmetysRepositoryException - if an error occurs.

hashAsList

public static List<String> hashAsList(String name)

Computes a hashed path in the JCR tree from the name of the child object.
Subclasses may override this method to provide a more suitable hash function.
This implementation relies on the buzhash algorithm. This method MUST return an array of the same length for each name.

Parameters:

name - the name of the child object

Returns:

a hashed path of the name.

getFullHashPath

public static String getFullHashPath(String name)

Get the path with hashed nodes.

Parameters:

name - the name of the final node

Returns:

the path with hashed nodes

getOrCreateFinalHashNode

public static javax.jcr.Node getOrCreateFinalHashNode(javax.jcr.Node parentNode,
 String name)
                                               throws AmetysRepositoryException

Get or create hash nodes for the given name, intermediate nodes are of type "ametys:collectionElement". The final node is not created. The session is not saved.

Parameters:

parentNode - the parent node of the hashed nodes

name - the name of the final node.

Returns:

the last level of hashed nodes

Throws:

AmetysRepositoryException - if an error occurs

getOrCreateFinalHashNode

public static javax.jcr.Node getOrCreateFinalHashNode(javax.jcr.Node parentNode,
 String name,
 String hashType)
                                               throws AmetysRepositoryException

Get or create hash nodes for the given name and intermediate primary type. The final node is not created. The session is not saved.

Parameters:

parentNode - the parent node of the hashed nodes

name - the name of the final node.

hashType - the primary type of hashed nodes

Returns:

the last level of hashed nodes

Throws:

AmetysRepositoryException - if an error occurs
