Interface Node

All Superinterfaces:

Comparable<Vertex>, Serializable, Vertex

All Known Implementing Classes:

NodeImpl

public interface Node
extends Vertex

Node is a vertex but not all vertices are nodes. Nodes represent locations in the physical network where links intersect, usually representing junctions or intersections

Method Detail

getExternalId

Object getExternalId()

Collect the external id of the node

Returns:

external id

setExternalId

void setExternalId(Object externalId)

Set the external id of the node

Parameters:

externalId - the external id to set

hasExternalId

boolean hasExternalId()

Returns whether the node has an external Id set

Returns:

true if the node has an external Id, false otherwise

getNodeId

long getNodeId()

Collect the id of the node. Not all vertices need to be nodes, this node id is contiguous and unique to the nodes in the network, but not necesssarily across all vertices in the network

Returns:

node id
