Enum Cluster.DnsLookupFamily

  • All Implemented Interfaces:
    com.google.protobuf.Internal.EnumLite, com.google.protobuf.ProtocolMessageEnum, java.io.Serializable, java.lang.Comparable<Cluster.DnsLookupFamily>
    Enclosing class:
    Cluster

    public static enum Cluster.DnsLookupFamily
    extends java.lang.Enum<Cluster.DnsLookupFamily>
    implements com.google.protobuf.ProtocolMessageEnum
     When V4_ONLY is selected, the DNS resolver will only perform a lookup for
     addresses in the IPv4 family. If V6_ONLY is selected, the DNS resolver will
     only perform a lookup for addresses in the IPv6 family. If AUTO is
     specified, the DNS resolver will first perform a lookup for addresses in
     the IPv6 family and fallback to a lookup for addresses in the IPv4 family.
     This is semantically equivalent to a non-existent V6_PREFERRED option.
     AUTO is a legacy name that is more opaque than
     necessary and will be deprecated in favor of V6_PREFERRED in a future major version of the API.
     If V4_PREFERRED is specified, the DNS resolver will first perform a lookup for addresses in the
     IPv4 family and fallback to a lookup for addresses in the IPv6 family. i.e., the callback
     target will only get v6 addresses if there were NO v4 addresses to return.
     If ALL is specified, the DNS resolver will perform a lookup for both IPv4 and IPv6 families,
     and return all resolved addresses. When this is used, Happy Eyeballs will be enabled for
     upstream connections. Refer to :ref:`Happy Eyeballs Support <arch_overview_happy_eyeballs>`
     for more information.
     For cluster types other than
     :ref:`STRICT_DNS<envoy_v3_api_enum_value_config.cluster.v3.Cluster.DiscoveryType.STRICT_DNS>` and
     :ref:`LOGICAL_DNS<envoy_v3_api_enum_value_config.cluster.v3.Cluster.DiscoveryType.LOGICAL_DNS>`,
     this setting is
     ignored.
     [#next-major-version: deprecate AUTO in favor of a V6_PREFERRED option.]

    • Method Detail

      • values

        public static Cluster.DnsLookupFamily[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (Cluster.DnsLookupFamily c : Cluster.DnsLookupFamily.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static Cluster.DnsLookupFamily valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
      • getNumber

        public final int getNumber()
        Specified by:
        getNumber in interface com.google.protobuf.Internal.EnumLite
        Specified by:
        getNumber in interface com.google.protobuf.ProtocolMessageEnum
      • valueOf

        @Deprecated
        public static Cluster.DnsLookupFamily valueOf​(int value)
        Deprecated.
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        value - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
      • forNumber

        public static Cluster.DnsLookupFamily forNumber​(int value)
        Parameters:
        value - The numeric wire value of the corresponding enum entry.
        Returns:
        The enum associated with the given numeric wire value.

      • valueOf

        public static Cluster.DnsLookupFamily valueOf​(com.google.protobuf.Descriptors.EnumValueDescriptor desc)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        desc - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
