Syntax

public String getUniversalID()
    throws NotesException
public void setUniversalID(String unid)
    throws NotesException

Usage

If two documents in replica databases share the same universal ID, the documents are replicas.

If you modify the UNID of an existing document, it becomes a new document.

Saving a document with the same UNID as an existing document throws NotesError.NOTES_MIN_ERROR_CODE (4000).

See DocumentUniqueID for another way to get the Universal ID of a document and more information.
