All Implemented Interfaces:

NodeOps, Serializable

public class NodeOpsImpl

extends BaseOps

implements NodeOps

A WLP Content Repository-to-ContentManager node ops.

The uid of IDs for Nodes from this will be the Content identifier.

The uid of IDs for Propertys from Nodes from this will be contentidentifier/propname
