pack-priv Class NameNode

extends Object
Class Inheritance
Known Direct Subclasses
com.sun.jndi.dns.ZoneNode
Imports
java.util.Hashtable
A NameNode represents a node in the DNS namespace. Each node has a label, which is its name relative to its parent (so the node at Sun.COM has label "Sun"). Each node has a hashtable of children indexed by their labels converted to lower-case.

A node may be addressed from another by giving a DnsName consisting of the sequence of labels from one node to the other.

Each node also has an isZoneCut flag, used to indicate if the node is a zone cut. A zone cut is a node with an NS record that is contained in one zone, but that actually belongs to a child zone.

All access is unsynchronized.
