               PolyLine3d designLine)
        throws NetworkException
        Construct a new OTSLink and register it in a Network. TODO should this method verify that the designLine is credible?

        endNode - Node; the end Node
        linkType - LinkType; the LinkType (stores compatibility with GTU types)
        designLine - PolyLine3d; the design line of the Link
        Throws:
        NetworkException - if link already exists in the network, or if name of the link is not unique, or if the start node or the end node of the link are not registered in the network.

    • Method Detail

      • getDirectionality

        public final LongitudinalDirectionality getDirectionality​(GtuType gtuType)
        This method returns the directionality of the link for a GTU type. It might be that the link is FORWARD (from start node to end node) for the GTU type CAR, but BOTH for the GTU type BICYCLE (i.e., bicycles can also go from end node to start node). If there is no entry for the given GTU Type, the values of GTUType.ALL will be returned. If this entry is not present, LongitudinalDirectionality.NONE will be returned.
        Specified by:
        getDirectionality in interface Link
        Parameters:
        gtuType - GtuType; the GTU type to request the directionality for
        Returns:
        the longitudinal directionality of the link (FORWARD, BACKWARD, BOTH or NONE) for the given GTU type. NONE will be returned if no directionality is given.

      • addGTU

        @Deprecated
public final void addGTU​(Gtu gtu)
        Deprecated.
        Add a GTU to this link (e.g., for statistical purposes, or for a model on macro level). It is safe to add a GTU again. No warning or error will be given. The GTU_ADD_EVENT will only be fired when the GTU was not already on the link.
        Specified by:
        addGTU in interface Link
        Parameters:
        gtu - Gtu; the GTU to add.

      • removeGTU

        @Deprecated
public final void removeGTU​(Gtu gtu)
        Deprecated.
        Remove a GTU from this link. It is safe to try to remove a GTU again. No warning or error will be given. The GTU_REMOVE_EVENT will only be fired when the GTU was on the link.
        Specified by:
        removeGTU in interface Link
        Parameters:
        gtu - Gtu; the GTU to remove.

      • getGTUs

        @Deprecated
public final Set<Gtu> getGTUs()
        Deprecated.
        Provide a safe copy of the set of GTUs.
        Specified by:
        getGTUs in interface Link
        Returns:
        Set<GTU>; a safe copy of the set of GTUs

      • getGTUCount

        @Deprecated
public final int getGTUCount()
        Deprecated.
        Provide the number of GTUs on this link.
        Specified by:
        getGTUCount in interface Link
        Returns:
        int; the number of GTUs on this link

      • getNetwork

        public Network getNetwork()
        Return the network in which this link is registered. Cannot be null.
        Specified by:
        getNetwork in interface Link
        Returns:
        Network; the network in which this link is registered

      • getStartNode

        public final Node getStartNode()
        Specified by:
        getStartNode in interface Link
        Returns:
        start node.

      • getEndNode

        public final Node getEndNode()
        Specified by:
        getEndNode in interface Link
        Returns:
        end node.

      • clone

        public OTSLink clone​(OTSNetwork newNetwork)
              throws NetworkException
        Clone this OTSLink for e.g., copying a network.
        Parameters:

        Returns:
        a clone of this object
        Throws:
        NetworkException - in case the cloning fails, a Link with the same name exists in newNetwork, etc.
