Method Detail

valueOf

public static MACAddress valueOf(String address)

Returns a MAC address instance representing the value of the specified String.

Parameters:

address - the String representation of the MAC Address to be parsed.

Returns:

a MAC Address instance representing the value of the specified String.

Throws:

IllegalArgumentException - if the string cannot be parsed as a MAC address.

valueOf

public static MACAddress valueOf(byte[] address)

Returns a MAC address instance representing the specified byte array.

Parameters:

address - the byte array to be parsed.

Returns:

a MAC address instance representing the specified byte array.

Throws:

IllegalArgumentException - if the byte array cannot be parsed as a MAC address.

valueOf

public static MACAddress valueOf(long address)

Returns a MAC address instance representing the specified long value. The lower 48 bits of the long value are used to parse as a MAC address.

Parameters:

address - the long value to be parsed. The lower 48 bits are used for a MAC address.

Returns:

a MAC address instance representing the specified long value.

Throws:

IllegalArgumentException - if the long value cannot be parsed as a MAC address.

length

public int length()

Returns the length of the MACAddress.

Returns:

the length of the MACAddress.

toBytes

public byte[] toBytes()

Returns the value of the MACAddress as a byte array.

Returns:

the numeric value represented by this object after conversion to type byte array.

toLong

public long toLong()

Returns:

the numeric value represented by this object after conversion to type long.

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 the multicast address.

Returns:

true if the MAC address is the multicast address.

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
