Topology- and Topology Group Specification
Note: There is a newer version of this specification see VEC 2.0.2
A TopologySpecification is a container for various TopologyNodes, TopologySegments and Zones. A TopologyNode represents an abstract place (meaning without concrete coordinates) in the wiring harness that can be typed either as EndNode, JunctionPoint or Inliner.
A TopologySegment represents a section of a connection or a wiring harness where no intermediate electrical contacts appear. In consequence, at the beginning and at the end of a TopologySegment the same wires go in and out. The beginning and the end are each defined by a dedicated reference to a TopologyNode. A TopologySegment can specify various SegmentCrossSectionAreas. These SegmentCrossSectionAreas are not supposed to express configuration-dependant values but different views (Calculated, Measured or Estimated) on the same type-dependant value whereupon the default-type is “reserved design space”. The same applies to SegmentLength.
A Zone represents a certain topology section, e.g. a certain design space and can specify various subZones.
In contrast to GEO 1.0 the VEC recognises an explicit grouping mechanism for topology. For this the VEC has introduced the class TopologyGroupSpecification which primary acts as a “normal” TopologySpecification being a container for various TopologyNodes, TopologySegments and Zones. However, a TopologyGroupSpecification can additionally reference the TopologySpecifications that it groups.
