@Nonnull
public static MacAddress of(@Nonnull
                                     String macString)
                              throws IllegalArgumentException

Parse a mac adress from the canonical string representation as 6 hex bytes separated by colons (01:02:03:04:05:06).

Parameters:

macString - - a mac address in canonical string representation

Returns:

the parsed MacAddress

Throws:

IllegalArgumentException - if macString is not a valid mac adddress

of

public static MacAddress of(@Nonnull
                            DatapathId dpid)

Creates a MacAddress from a DatapathId. This factory method assumes that the first two bytes of the DatapathId are 0 bytes.

Parameters:

dpid - the DatapathId to create the MacAddress from

Returns:

a MacAddress derived from the supplied DatapathId

getBytes

public byte[] getBytes()

isBroadcast

public boolean isBroadcast()

Returns true if the MAC address is the broadcast address.

Returns:

true if the MAC address is the broadcast address.

isMulticast

public boolean isMulticast()

Returns true if the MAC address is a multicast address.

Returns:

true if the MAC address is a multicast address.

isLLDPAddress

public boolean isLLDPAddress()

Returns true if the MAC address is an LLDP mac address.

Returns:

true if the MAC address is an LLDP mac address.

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:
