org.apache.directory.shared.ldap.model.name.Dn
The Dn class contains a Dn (Distinguished Name). This class is immutable.
Its specification can be found in RFC 2253, "UTF-8 String Representation of Distinguished Names".
We will store two representation of a Dn :
- a user Provider representation, which is the parsed String given by a user
- an internal representation.
A Dn is formed of RDNs, in a specific order :
Rdn[n], Rdn[n-1], ... Rdn[1], Rdn[0]
It represents a position in a hierarchy, in which the root is the last Rdn (Rdn[0]) and the leaf is the first Rdn (Rdn[n]). @author Apache Directory Project
