com.linecorp.armeria.common.util.InetAddressPredicates

public final class InetAddressPredicates
extends Object

A utility class which provides factory methods in order to easily create a Predicate of an InetAddress.

Method Summary

Modifier and Type	Method	Description
static Predicate<InetAddress>	ofCidr(String cidr)	Returns a Predicate which returns true if the given InetAddress is in the range of a Classless Inter-domain Routing (CIDR) block.
static Predicate<InetAddress>	ofCidr(InetAddress baseAddress, int maskBits)	Returns a Predicate which returns true if the given InetAddress is in the range of a Classless Inter-domain Routing (CIDR) block.
static Predicate<InetAddress>	ofCidr(InetAddress baseAddress, String subnetMask)	Returns a Predicate which returns true if the given InetAddress is in the range of a Classless Inter-domain Routing (CIDR) block.
static Predicate<InetAddress>	ofExact(String address)	Returns a Predicate which returns true if the given InetAddress equals to the specified address.
static Predicate<InetAddress>	ofExact(InetAddress address)	Returns a Predicate which returns true if the given InetAddress equals to the specified address.

Method Details

ofExact

public static Predicate<InetAddress> ofExact(InetAddress address)

Returns a Predicate which returns true if the given InetAddress equals to the specified address.

Parameters:

address - the expected InetAddress

ofExact

public static Predicate<InetAddress> ofExact(String address)

Returns a Predicate which returns true if the given InetAddress equals to the specified address.

Parameters:

address - the expected IP address string, e.g. 10.0.0.1

ofCidr

public static Predicate<InetAddress> ofCidr(InetAddress baseAddress, int maskBits)

Returns a Predicate which returns true if the given InetAddress is in the range of a Classless Inter-domain Routing (CIDR) block.

Parameters:

baseAddress - the base InetAddress of a CIDR notation

maskBits - the number of significant bits which describes its network portion

ofCidr

public static Predicate<InetAddress> ofCidr(InetAddress baseAddress, String subnetMask)

Returns a Predicate which returns true if the given InetAddress is in the range of a Classless Inter-domain Routing (CIDR) block.

Parameters:

baseAddress - the base InetAddress of a CIDR notation

subnetMask - the subnet mask, e.g. 255.255.255.0

ofCidr

public static Predicate<InetAddress> ofCidr(String cidr)

Returns a Predicate which returns true if the given InetAddress is in the range of a Classless Inter-domain Routing (CIDR) block.

Parameters:

cidr - the CIDR notation of an address block, e.g. 10.0.0.0/8, 192.168.1.0/24, 1080:0:0:0:8:800:200C:4100/120. If it's an exact IP address such as 10.1.1.7 or 1080:0:0:0:8:800:200C:4100, the mask bits is considered as 32 for IPv4 or 128 for IPv6.
