Examples of org.exist.numbering.NodeId

org.exist.numbering.NodeId
Represents the internal id of a node within eXist. Basically, all stored nodes in eXist need to have an id that implements this interface. The id will be assigned according to used numbering scheme. From a given id, we can determine the relationship of the node it represents to any other node in the same document.
