接口 DnsServerResponseFeedbackAddressStream

所有超级接口:

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.

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

参数:

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

参数:

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
