Field Detail

type

private final short type

[htype] Hardware address type, see ARP section in "Assigned Numbers" RFC; e.g., '1' = 10mb ethernet.

length

private final short length

[hlen] Hardware address length (e.g. '6' for 10mb ethernet).

Constructor Detail

HardwareAddress

public HardwareAddress(short type,
                       short length,
                       byte[] address)

Parameters:

type -

length -

address -

Method Detail

getAddress

public byte[] getAddress()

getLength

public short getLength()

getType

public short getType()

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

Returns:

the instance's hash code

See Also:

Object.hashCode()

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

getNativeRepresentation

public java.lang.String getNativeRepresentation()

Create the string representation of the hardware address native to the corresponding address type. This method currently supports only type 1==ethernet with the representation a1:a2:a3:a4:a5:a6.
For all other types, this method falls back to the representation created by toString().

See Also:

Object.toString()

toString

public java.lang.String toString()

Create a string representation of the hardware address. The string representation is in the format
t/a1:a2:a3...
Where t represents the address type (decimal) and an represent the address bytes (hexadecimal).

Overrides:

toString in class java.lang.Object

See Also:

Object.toString()

valueOf

public static HardwareAddress valueOf(java.lang.String s)

Parses a string representation of a hardware address according to the specification given in toString().

Parameters:

s -

Returns:

HardwareAddress

Throws:

ParseException
