DnsServerResponseFeedbackAddressStream (Netty API Reference (4.2.1.Final))

All Superinterfaces:

DnsServerAddressStream
```
public interface DnsServerResponseFeedbackAddressStream
extends DnsServerAddressStream
```
An infinite stream of DNS server addresses, that requests feedback to be returned to it. If query is successful timing information is provided, else a failure notification is given.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`feedbackFailure(java.net.InetSocketAddress address, java.lang.Throwable failureCause, long queryResponseTimeNanos)`	A way to provide failure feedback to `DnsServerAddressStream` so that `DnsServerAddressStream.next()` cab be tuned to return the best performing DNS server address
`void`	`feedbackSuccess(java.net.InetSocketAddress address, long queryResponseTimeNanos)`	A way to provide success feedback to `DnsServerAddressStream` so that `DnsServerAddressStream.next()` can be tuned to return the best performing DNS server address NOTE: This is called regardless of the RCode returned by the DNS server

  - feedbackSuccess
```
void feedbackSuccess(java.net.InetSocketAddress address,
                     long queryResponseTimeNanos)
```
    A way to provide success feedback to DnsServerAddressStream so that DnsServerAddressStream.next() can be tuned to return the best performing DNS server address NOTE: This is called regardless of the RCode returned by the DNS server
    
    Parameters:
    
    address - The address returned by DnsServerAddressStream.next() that feedback needs to be applied to
    
    queryResponseTimeNanos - The response time of a query against the given DNS server
  - feedbackFailure
```
void feedbackFailure(java.net.InetSocketAddress address,
                     java.lang.Throwable failureCause,
                     long queryResponseTimeNanos)
```
    A way to provide failure feedback to DnsServerAddressStream so that DnsServerAddressStream.next() cab be tuned to return the best performing DNS server address
    
    Parameters:
    
    address - The address returned by DnsServerAddressStream.next() that feedback needs to be applied to
    
    failureCause - The reason the DNS query failed, can be used to penalize failures differently
    
    queryResponseTimeNanos - The response time of a query against the given DNS server
