Class AddressUtils

java.lang.Object

reactor.netty.transport.AddressUtils

public final class AddressUtils
extends java.lang.Object

Internal class that creates unresolved or resolved InetSocketAddress instances Numeric IPv4 and IPv6 addresses will be detected and parsed by using Netty's NetUtil.createByteArrayFromIpAddressString(java.lang.String) utility method and the InetSocketAddress instances will created in a way that these instances are resolved initially. This removes the need to do unnecessary reverse DNS lookups.

Method Summary

Modifier and Type	Method and Description
static java.net.InetSocketAddress	createInetSocketAddress(java.lang.String hostname, int port, boolean resolve) Creates InetSocketAddress instance.
static java.net.InetSocketAddress	createResolved(java.lang.String hostname, int port) Creates InetSocketAddress that is always resolved.
static java.net.InetSocketAddress	createUnresolved(java.lang.String hostname, int port) Creates unresolved InetSocketAddress.
static java.net.InetSocketAddress	parseAddress(java.lang.String address, int defaultPort) Parse unresolved InetSocketAddress.
static java.net.InetSocketAddress	replaceUnresolvedNumericIp(java.net.InetSocketAddress inetSocketAddress) Replaces an unresolved InetSocketAddress with a resolved instance in the case that the passed address is a numeric IP address (both IPv4 and IPv6 are supported).
static java.net.InetSocketAddress	replaceWithResolved(java.net.InetSocketAddress inetSocketAddress) Replaces an unresolved InetSocketAddress with a resolved instance in the case that the passed address is unresolved.
static java.net.SocketAddress	updateHost(java.util.function.Supplier<? extends java.net.SocketAddress> address, java.lang.String host) Update the provided address with the new host string.
static java.net.SocketAddress	updatePort(java.util.function.Supplier<? extends java.net.SocketAddress> address, int port) Update the provided address with the new port.

Method Detail

createInetSocketAddress

public static java.net.InetSocketAddress createInetSocketAddress(java.lang.String hostname,
                                                                 int port,
                                                                 boolean resolve)

Creates InetSocketAddress instance. Numeric IP addresses will be detected and resolved without doing reverse DNS lookups.

Parameters:

hostname - ip-address or hostname

port - port number

resolve - when true, resolve given hostname at instance creation time

Returns:

InetSocketAddress for given parameters

createResolved

public static java.net.InetSocketAddress createResolved(java.lang.String hostname,
                                                        int port)

Creates InetSocketAddress that is always resolved. Numeric IP addresses will be detected and resolved without doing reverse DNS lookups.

Parameters:

hostname - ip-address or hostname

port - port number

Returns:

InetSocketAddress for given parameters

createUnresolved

public static java.net.InetSocketAddress createUnresolved(java.lang.String hostname,
                                                          int port)

Creates unresolved InetSocketAddress. Numeric IP addresses will be detected and resolved.

Parameters:

hostname - ip-address or hostname

port - port number

Returns:

InetSocketAddress for given parameters

parseAddress

public static java.net.InetSocketAddress parseAddress(java.lang.String address,
                                                      int defaultPort)

Parse unresolved InetSocketAddress. Numeric IP addresses will be detected and resolved.

Parameters:

address - ip-address or hostname

defaultPort - the default port

Returns:

InetSocketAddress for given parameters

replaceUnresolvedNumericIp

public static java.net.InetSocketAddress replaceUnresolvedNumericIp(java.net.InetSocketAddress inetSocketAddress)

Replaces an unresolved InetSocketAddress with a resolved instance in the case that the passed address is a numeric IP address (both IPv4 and IPv6 are supported).

Parameters:

inetSocketAddress - socket address instance to process

Returns:

processed socket address instance

replaceWithResolved

public static java.net.InetSocketAddress replaceWithResolved(java.net.InetSocketAddress inetSocketAddress)

Replaces an unresolved InetSocketAddress with a resolved instance in the case that the passed address is unresolved.

Parameters:

inetSocketAddress - socket address instance to process

Returns:

resolved instance with same host string and port

updateHost
