public class DNSCache extends ConcurrentHashMap<String,List<DNSEntry>>
for (Iterator i=dnscache.allValues().iterator(); i.hasNext(); ) { DNSEntry entry = i.next(); ...do something with entry... }And here's how to iterate over all entries having a given name:
for (Iterator i=dnscache.getDNSEntryList(name).iterator(); i.hasNext(); ) { DNSEntry entry = i.next(); ...do something with entry... }
