public class ChangeLogImpl
extends Object
implements ChangeLog

This ChangeLog implementation simply keeps back all calls to its Batch methods as a list of operations (with item of type Operation). When applied to a batch, all operations in the list are applied to that batch.

             throws RepositoryException

Description copied from interface: Batch

Add a new node to the persistent layer.

Specified by:

addNode in interface Batch

Parameters:

parentId - NodeId identifying the parent node.

nodeName - Name of the node to be created.

nodetypeName - Primary node type name of the node to be created.

uuid - Value for the jcr:uuid property of the node to be created or null. If due to an import the uuid of the resulting node is already defined, it must be passed as separate uuid parameter, indicating a binding value for the server. Otherwise the uuid must be null.
