Enum Constant Detail

IPV4_ONLY

public static final DnsResolverAddressTypes IPV4_ONLY

Only resolve IPv4 addresses.

IPV6_ONLY

public static final DnsResolverAddressTypes IPV6_ONLY

Only resolve IPv6 addresses.

IPV4_PREFERRED

public static final DnsResolverAddressTypes IPV4_PREFERRED

Attempt to resolve both, prefer IPv4 addresses over IPv6 ones. Failure to resolve IPv6 won't result in an error.

IPV6_PREFERRED

public static final DnsResolverAddressTypes IPV6_PREFERRED

Attempt to resolve both, prefer IPv6 addresses over IPv4 ones. Failure to resolve IPv4 won't result in an error.

IPV4_PREFERRED_RETURN_ALL

public static final DnsResolverAddressTypes IPV4_PREFERRED_RETURN_ALL

Attempt to resolve IPv4 and IPv6 addresses, return all results. Failure to resolve IPv6 won't result in an error.

IPV6_PREFERRED_RETURN_ALL

public static final DnsResolverAddressTypes IPV6_PREFERRED_RETURN_ALL

Attempt to resolve IPv6 and IPv4 addresses, return all results. Failure to resolve IPv4 won't result in an error.

Method Detail

values

public static DnsResolverAddressTypes[] 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 (DnsResolverAddressTypes c : DnsResolverAddressTypes.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DnsResolverAddressTypes valueOf(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:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
