Resolve host to the first ip addresses allowing for connection attempts to try just that first ip addresses for a given hostname. Includes IPV6 addresses.

Unresolved

public static final Options.HostnameResolveMode Unresolved

Do not resolve, instead use InetSocketAddress.createUnresolved while creating the socket.

HappyEyeballs

Method Detail

values

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

Returns:

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

valueOf

public static Options.HostnameResolveMode 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

get
