public DnsServerAddresses()

Method Detail

defaultAddressList

@Deprecated
public static List<InetSocketAddress> defaultAddressList()

Deprecated.

Use DefaultDnsServerAddressStreamProvider.defaultAddressList().

Returns the list of the system DNS server addresses. If it failed to retrieve the list of the system DNS server addresses from the environment, it will return "8.8.8.8" and "8.8.4.4", the addresses of the Google public DNS servers.

defaultAddresses

@Deprecated
public static DnsServerAddresses defaultAddresses()

Deprecated.

Use DefaultDnsServerAddressStreamProvider.defaultAddresses().

Returns the DnsServerAddresses that yields the system DNS server addresses sequentially. If it failed to retrieve the list of the system DNS server addresses from the environment, it will use "8.8.8.8" and "8.8.4.4", the addresses of the Google public DNS servers.

This method has the same effect with the following code:

 DnsServerAddresses.sequential(DnsServerAddresses.defaultAddressList());
 

sequential

public static DnsServerAddresses sequential(Iterable<? extends InetSocketAddress> addresses)

Returns the DnsServerAddresses that yields the specified addresses sequentially. Once the last address is yielded, it will start again from the first address.

sequential

public static DnsServerAddresses sequential(InetSocketAddress... addresses)

Returns the DnsServerAddresses that yields the specified addresses sequentially. Once the last address is yielded, it will start again from the first address.

shuffled

public static DnsServerAddresses shuffled(Iterable<? extends InetSocketAddress> addresses)

Returns the DnsServerAddresses that yields the specified address in a shuffled order. Once all addresses are yielded, the addresses are shuffled again.

shuffled

public static DnsServerAddresses shuffled(InetSocketAddress... addresses)

Returns the DnsServerAddresses that yields the specified addresses in a shuffled order. Once all addresses are yielded, the addresses are shuffled again.

rotational

public static DnsServerAddresses rotational(Iterable<? extends InetSocketAddress> addresses)

Returns the DnsServerAddresses that yields the specified addresses in a rotational sequential order. It is similar to sequential(Iterable), but each DnsServerAddressStream starts from a different starting point. For example, the first stream() will start from the first address, the second one will start from the second address, and so on.

rotational

public static DnsServerAddresses rotational(InetSocketAddress... addresses)

Returns the DnsServerAddresses that yields the specified addresses in a rotational sequential order. It is similar to sequential(Iterable), but each DnsServerAddressStream starts from a different starting point. For example, the first stream() will start from the first address, the second one will start from the second address, and so on.

singleton

public static DnsServerAddresses singleton(InetSocketAddress address)

Returns the DnsServerAddresses that yields only a single address.

stream

public abstract DnsServerAddressStream stream()

Starts a new infinite stream of DNS server addresses. This method is invoked by DnsNameResolver on every uncached SimpleNameResolver.resolve(String)or SimpleNameResolver.resolveAll(String).
