public Inet4AddressWithSubnetmask(String label,
 Inet4Address inet4Address,
 int subnetmask)

Method Details

fromString

public static Inet4AddressWithSubnetmask fromString(String value)
                                             throws OpenemsException

Parse a string in the form "192.168.100.100/24" to an IPv4 address. Label is set to an empty string with this factory method.

Parameters:

value - the string in the form "192.168.100.100/24"

Returns:

the new Inet4AddressWithSubnetmask

Throws:

OpenemsException - on error

fromString

public static Inet4AddressWithSubnetmask fromString(String label,
 String value)
                                             throws OpenemsException

Parse a string in the form "192.168.100.100/24" to an IPv4 address.

Parameters:

label - a label string

value - the string in the form "192.168.100.100/24"

Returns:

the new Inet4AddressWithSubnetmask

Throws:

OpenemsException - on error

getCidrFromSubnetmask

public static int getCidrFromSubnetmask(Inet4Address subnetmask)
                                 throws OpenemsException

Converts the Subnetmask to a CIDR number.

e. g. Converts "255.255.255.0" to "24".

Parameters:

subnetmask - the subnetmask.

Returns:

the CIDR number.

Throws:

OpenemsException

getLabel

public String getLabel()

getInet4Address

public Inet4Address getInet4Address()

getSubnetmaskAsCidr

public int getSubnetmaskAsCidr()

Returns:

the subnetmask

getSubnetmaskAsString

public final String getSubnetmaskAsString()

Gets the Subnetmask in string format, e.g. "255.255.255.0" for "24".

Returns:

the subnetmask

toString

public String toString()

Overrides:

toString in class Object

isInSameNetwork

public boolean isInSameNetwork(Inet4AddressWithSubnetmask other)

Determines if this address and the given address are in the same network.

Parameters:

other - the other Inet4AddressWithSubnetmask

Returns:

true if they are in the same network

hashCode
