Interface Node

All Superinterfaces:

Model, NetworkElement

All Known Implementing Classes:

DefaultNode

public interface Node
extends NetworkElement

Node is a network terminal entity, meaning a leaf, and has a single Interface. A multi-homed system is modeled as multiple nodes.

Any node is uniquely identified by IpAddress and SegmentId. Any other information about the node is not guaranteed to be unique, and may be unknown.

supplierId

Method Detail

id

NodeId id()

Returns the globally-unique identifier of this node.

Specified by:

id in interface NetworkElement

Returns:

node identifier

ip

IpAddress ip()

Returns the IPv4 or IPv6 address of this node.

Returns:

the IP address

segmentId

SegmentId segmentId()

Returns the network segment id on which this node has been discovered.

Returns:

segment id.

netInterface

Interface netInterface()

Returns the network interface through which the node attaches to the network. This is an interface on the node itself, not the interface on a Device to which the node is attached.

Returns:

node network interface; null if unknown

mac

MacAddress mac()

Returns the MAC address of this node.

Returns:

the node MAC; null if unknown

location

NodeLocation location()

Returns the most recent node location.

Returns:

node location; null if unknown

recentLocations

List<NodeLocation> recentLocations()

Returns the list of recent node locations. The most recent location will be at the beginning of the list, which may be empty if no recent location is known.

Returns:

recent node locations

timeout

long timeout()

Returns the original time offset (in seconds) after which the node would be removed.

Returns:

removal time offset, in seconds

check

@Deprecated
boolean check(NodeInfo info)

Deprecated.

Deprecated Checks whether this node would be changed by applying the given information. This method gives the same return value as update(NodeInfo) without modifying this object.

Parameters:

info - given node information

Returns:

whether the update would change any node data, if applied

update

@Deprecated
boolean update(NodeInfo info)

Deprecated.

Deprecated Updates this node based upon applying the given information.

Parameters:

info - given node information

Returns:

whether the update changed any node data
