- public interface IdNode
Base node for identifiable NewsML objects.
Most NewsML objects can have a Duid (document-unique
identifiers) and/or Euid (element-unique identifier) attached. All
such objects are derived from this class.

getDuid
public Text getDuid()
- Get the Duid for this element.
The Duid, or Document-Unique Identifier, is a string identifier
guaranteed to be unique within this NewsML package. Duids are
heavily used for cross-referencing.
- Returns:
- Text containing the document-unique identifier for the
underlying XML element, or null if none was specified.
getEuid
public Text getEuid()
- Get the Euid for this element.
The Euid, or Element-Unique Identifier is not likely to be used
widely -- it's an identifier that unique only among elements
with the same type and parent (and thus, is virtually useless
for cross-referencing). This toolkit includes access to the
Euid simply for the sake of completeness, but all of its
retrieval and cross-referencing support is based on the Duid.
Note that this method will always return null for instances of
the
NewsIdentifier, RevisionId, and TopicUse classes.
- Returns:
- Text containing the element-unique identifier for the
underlying XML element, or null if none was specified.
