The path of the Node, or null if node is null or an exception happens.

getNodeNameQuietly

public static String getNodeNameQuietly(javax.jcr.Node node)

Get the name of a Node, or null if the node cannot be retrieved.

This method is mainly provided for convenience of usage, so a developer does not have to worry about exception handling in case it is not of interest.

getNextSiblingIfExists

public static javax.jcr.Node getNextSiblingIfExists(javax.jcr.Node current)
                                             throws javax.jcr.RepositoryException

Returns the next sibling Node of current. If there is no next sibling it returns null. If the parent Node of current is not an orderable Node, an UnsupportedRepositoryOperationException will be thrown. Checking whether the parent is orderable can be done easily as follows

         Node parent = current.getParent();
         parent.getPrimaryNodeType().hasOrderableChildNodes()
 

If the caller of this method uses this method to reorder nodes, then take into account whether the parent node allows same name siblings or not. If you do not know, use

         Node parent = current.getParent();
         if (parent.getDefinition().allowsSameNameSiblings()) {
             Node next = getNextSiblingIfExists(current);
             parent.orderBefore(current.getName() + "[" + current.getIndex() + "]",
                                next.getName()+ "[" + next.getIndex() + "]");
         } else {
             parent.orderBefore(current.getName(), getNextSiblingIfExists(current).getName());
         }
 

Parameters:

current - the Node for which to find the next sibling

Returns:

the next sibling of current if there is a next one and null in case there is no next sibling

Throws:

javax.jcr.UnsupportedRepositoryOperationException - if the parent of current is not orderable

javax.jcr.RepositoryException - if some repository exception happens
