NeighborSolicitation

public NeighborSolicitation()

Method Detail

getTargetAddress

public byte[] getTargetAddress()

Gets target address.

Returns:

the target IPv6 address

setTargetAddress

public NeighborSolicitation setTargetAddress(byte[] targetAddress)

Sets target address.

Parameters:

targetAddress - the target IPv6 address to set

Returns:

this

getOptions

public List<NeighborDiscoveryOptions.Option> getOptions()

Gets the Neighbor Discovery Protocol packet options.

Returns:

the Neighbor Discovery Protocol packet options

addOption

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

Adds a Neighbor Discovery Protocol packet option.

Parameters:

type - the option type

data - the option data

Returns:

this

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<NeighborSolicitation> deserializer()

Deserializer function for neighbor solicitation packets.

Returns:

deserializer function

toString

public String toString()

Overrides:

toString in class Object

buildNdpSolicit

public static Ethernet buildNdpSolicit(byte[] targetIp,
                                       byte[] sourceIp,
                                       byte[] destinationIp,
                                       byte[] sourceMac,
                                       byte[] destinationMac,
                                       VlanId vlan)

Builds a NDP solicitation using the supplied parameters.

Parameters:

targetIp - the target ip

sourceIp - the source ip

destinationIp - the destination ip

sourceMac - the source mac address

destinationMac - the destination mac address

vlan - the vlan id

Returns:

the ethernet packet containing the ndp solicitation
