Direct Known Subclasses:
DnssecResolverApi
public class ResolverApi extends Object
The high-level MiniDNS resolving API. It is designed to be easy to use.

A simple exammple how to resolve the IPv4 address of a given domain: 


ResolverResult<A> result = DnssecResolverApi.INSTANCE.resolve("verteiltesysteme.net", A.class);
if (!result.wasSuccessful()) {
  RESPONSE_CODE responseCode = result.getResponseCode();
  // Perform error handling.
  …
  return;
}
if (!result.isAuthenticData()) {
  // Response was not secured with DNSSEC.
  …
  return;
}
Set<A> answers = result.getAnswers();
for (A a : answers) {
  InetAddress inetAddress = a.getInetAddress();
  // Do someting with the InetAddress, e.g. connect to.
  …
}

MiniDNS also supports SRV resource records as first class citizens: 


SrvResolverResult result = DnssecResolverApi.INSTANCE.resolveSrv(SrvType.xmpp_client, "example.org")
if (!result.wasSuccessful()) {
  RESPONSE_CODE responseCode = result.getResponseCode();
  // Perform error handling.
  …
  return;
}
if (!result.isAuthenticData()) {
  // Response was not secured with DNSSEC.
  …
  return;
}
List<ResolvedSrvRecord> srvRecords = result.getSortedSrvResolvedAddresses();
// Loop over the domain names pointed by the SRV RR. MiniDNS will return the list
// correctly sorted by the priority and weight of the related SRV RR.
for (ResolvedSrvRecord srvRecord : srvRecord) {
  // Loop over the Internet Address RRs resolved for the SRV RR. The order of
  // the list depends on the prefered IP version setting of MiniDNS.
  for (InternetAddressRR inetAddressRR : srvRecord.addresses) {
    InetAddress inetAddress = inetAddressRR.getInetAddress();
    int port = srvAddresses.port;
    // Try to connect to inetAddress at port.
    …
  }
}
