Method Detail

addOption

public NeighborDiscoveryOptions addOption(byte type,
                                          byte[] data)

Adds a Neighbor Discovery Protocol packet option.

Parameters:

type - the option type

data - the option data

Returns:

this

options

public List<NeighborDiscoveryOptions.Option> options()

Gets the Neighbor Discovery Protocol packet options.

Returns:

the Neighbor Discovery Protocol packet options

hasOptions

public boolean hasOptions()

Checks whether any options are included.

Returns:

true if options are included, otherwise false

serialize

public byte[] serialize()

Description copied from interface: IPacket

Sets all payloads parent packet if applicable, then serializes this packet and all payloads.

Returns:

a byte[] containing this packet and payloads

deserialize

public IPacket deserialize(byte[] data,
                           int offset,
                           int length)

Description copied from interface: IPacket

Deserialize this packet layer and all possible payloads. NOTE: This method has been deprecated and will be removed in a future release. It is now recommended to use the Deserializer function provided by the deserialize() method on each packet to deserialize them. The Deserializer functions are robust to malformed input.

Parameters:

data - bytes to deserialize

offset - offset to start deserializing from

length - length of the data to deserialize

Returns:

the deserialized data

hashCode

public int hashCode()

Overrides:

hashCode in class BasePacket

equals

public boolean equals(Object obj)

Overrides:

equals in class BasePacket

deserializer

public static Deserializer<NeighborDiscoveryOptions> deserializer()

toString

public String toString()

Overrides:

toString in class Object
