Class NFENetworkElement

  • All Implemented Interfaces:
    NFEModelObject
    Direct Known Subclasses:
    NFELink, NFENode
    public abstract class NFENetworkElement
extends NFEBasicModelObject
    This is the base class for nodes and links. It contains methods and properties common to both types of network elements.

        id - a node or link ID

      • getId

        public long getId()
        Gets the ID of the network element
        Returns:
        a node or link ID

      • setName

        public void setName​(java.lang.String name)
        Sets the name of the network element

        a boolean value indicating whether the network element is active or not

      • setCost

        public void setCost​(double cost)
        Sets the cost of the network element
        Parameters:
        cost - the network element's cost

        public double getCost()
        Gets the cost of the network element
        Returns:
        the network element's cost

      • setGeometry

        public void setGeometry​(JGeometry geometry)
        Sets the network element's geometry
        Parameters:
        geometry - a line string geometry for links, a point geometry for nodes

      • getGeometry

        public JGeometry getGeometry()
        gets the network element's geometry

        a line string geometry for links, a point geometry for nodes

      • setNetwork

        public void setNetwork​(NFENetwork network)
        Sets the network to which the network element belongs
        Parameters:
        network - a network instance

      • getNetwork

        public NFENetwork getNetwork()
        Gets the network to which the network element belongs
        Returns:
        a network instance or null the network element does not belong to any network

      • isNode

        public abstract boolean isNode()
        Tells whether the network element is a node or not
