Class DnsServerAddresses

java.lang.Object
io.netty.resolver.dns.DnsServerAddresses
Direct Known Subclasses:

public abstract class DnsServerAddresses extends java.lang.Object
Provides an infinite sequence of DNS server addresses to DnsNameResolver.

  • Method Details

    • defaultAddressList

      @Deprecated public static java.util.List<java.net.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(java.lang.Iterable<? extends java.net.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(java.net.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.

    • sequential0

      private static DnsServerAddresses sequential0(java.util.List<java.net.InetSocketAddress> addresses)

    • shuffled

      public static DnsServerAddresses shuffled(java.lang.Iterable<? extends java.net.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(java.net.InetSocketAddress... addresses)
      Returns the DnsServerAddresses that yields the specified addresses in a shuffled order. Once all addresses are yielded, the addresses are shuffled again.

    • shuffled0

      private static DnsServerAddresses shuffled0(java.util.List<java.net.InetSocketAddress> addresses)

    • rotational

      public static DnsServerAddresses rotational(java.lang.Iterable<? extends java.net.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(java.net.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.

    • rotational0

      private static DnsServerAddresses rotational0(java.util.List<java.net.InetSocketAddress> addresses)

    • singleton

      public static DnsServerAddresses singleton(java.net.InetSocketAddress address)
      Returns the DnsServerAddresses that yields only a single address.

    • sanitize

      private static java.util.List<java.net.InetSocketAddress> sanitize(java.lang.Iterable<? extends java.net.InetSocketAddress> addresses)

    • sanitize

      private static java.util.List<java.net.InetSocketAddress> sanitize(java.net.InetSocketAddress[] addresses)

    • 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).
