Method Detail

getNetwork

Network getNetwork()

Return the network in which this link is registered. Cannot be null.

Returns:

Network; the network in which this link is registered

getId

String getId()

Returns:

node id.

getPoint

OTSPoint3D getPoint()

Returns:

point.

getDirection

org.djunits.value.vdouble.scalar.Direction getDirection()

Returns:

the 3D direction. "East" is 0 degrees. "North" is 90 degrees (1/2 pi radians).

getSlope

org.djunits.value.vdouble.scalar.Direction getSlope()

Returns:

the slope as an angle. Horizontal is 0 degrees.

addLink

void addLink(Link link)

Add a link to this Node.

Parameters:

link - the link to add.

removeLink

void removeLink(Link link)

Remove a link from this Node.

Parameters:

link - the link to remove.

getLinks

ImmutableSet<Link> getLinks()

Returns:

a safe copy of the links connected to this Node

nextLinks

Set<Link> nextLinks(GTUType gtuType,
                    Link prevLink)
             throws NetworkException

Determine the links connecting from the previous link via this Node for the given GTU type.

Parameters:

gtuType - the GTU type to determine the next links for

prevLink - the incoming link to the Node

Returns:

a set of links connecting from the previous link via this Node for the given GTU type

Throws:

NetworkException - if thhe incoming link is not connected to this node for the given GTU type

isDirectionallyConnectedTo

boolean isDirectionallyConnectedTo(GTUType gtuType,
                                   Node toNode)

Check if the current node is linked to the given Node in the specified direction for the given GTUType. This can mean there is a Link from this node to toNode, and the LongitudinalDirectionality for the Link between this node and toNode is FORWARD or BOTH; or there is a Link from toNode to this node, and the LongitudinalDirectionality for the Link between toNode and this node is BACKWARD or BOTH for the provided GTUType.

Parameters:

gtuType - the GTU type to check the connection for.

toNode - the to node

Returns:

whether two nodes are linked in the specified direction.
