Detailed Description

A table of DNS entries. This is a map table which can handle multiple entries with the same name.

Storing multiple entries with the same name is implemented using a linked list. This is hidden from the user and can change in later implementation.

Here's how to iterate over all entries:

       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...
       }
