Lines Matching defs:zone
37 * A ZoneNode that represents a zone may be "populated" with a
38 * NameNode tree containing the zone's contents.
40 * <p> A populated zone's contents will be flagged as having expired after
41 * the time specified by the minimum TTL value in the zone's SOA record.
43 * <p> Since zone cuts aren't directly modeled by a tree of ZoneNodes,
48 * <p> The zone's contents are accessed via a soft reference, so its
49 * heap space may be reclaimed when necessary. The zone may be
