Package org.planit.network.virtual

Class ConnectoidSegmentImpl

java.lang.Object

org.planit.graph.EdgeSegmentImpl

org.planit.network.virtual.ConnectoidSegmentImpl

All Implemented Interfaces:

Serializable, Comparable<EdgeSegment>, EdgeSegment, ConnectoidSegment

public class ConnectoidSegmentImpl
extends EdgeSegmentImpl
implements ConnectoidSegment

The link segment that connects a zone to the physical network is not a physical link segment. However in order to be able to efficiently conduct path searches this connection needs to materialise in a similar form. to do this we construct ConnectoidLinkSegment instances which are a link segment, but do not have any physical characteristics apart from connecting a zone (via its centroid) to a physical node. these segments are NOT registered on the network because they are not part of the physical network, instead they are registered on the adopted zoning. they are however injected/connected to the connectoid reference nodes in the network as link segments to provide the above mentioned interface
