Field Detail

nodeId

protected final long nodeId

Unique node identifier

externalId

protected Object externalId

External identifier used in input files

Constructor Detail

NodeImpl

public NodeImpl(IdGroupingToken groupId)

Node constructor

Parameters:

groupId - contiguous id generation within this group for instances of this class

Method Detail

generateNodeId

protected static int generateNodeId(IdGroupingToken groupId)

generate unique node id

Parameters:

groupId - contiguous id generation within this group for instances of this class

Returns:

nodeId

getExternalId

public Object getExternalId()

Collect the external id of the node

Specified by:

getExternalId in interface Node

Returns:

external id

setExternalId

public void setExternalId(Object externalId)

Set the external id of the node

Specified by:

setExternalId in interface Node

Parameters:

externalId - the external id to set

hasExternalId

public boolean hasExternalId()

Returns whether the node has an external Id set

Specified by:

hasExternalId in interface Node

Returns:

true if the node has an external Id, false otherwise

getNodeId

public 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

Specified by:

getNodeId in interface Node

Returns:

node id
