APPENDIX A - Classes
Same As Geometry Edge

Class Name: Same As Geometry Edge

Superclass - <Geometry Same As>

Subclasses

This DRM class is concrete and has no subclasses.

Definition

An instance of this DRM class indicates that two or more <Geometry Edge> instances are the same <Geometry Edge>, so that the topologies they are a part of may be joined together by an application.

Secondary Pages in DRM Diagram:

This class appears on only one page of the DRM class diagram.

Example

  1. Consider a <Geometry Model> representing one lane of a road, containing a <Geometry Edge> corresponding to a line of lights. Consider two instances of this <Geometry Model> that are instanced to represent opposing lanes on the same road. Each of the actual <Geometry Edge> lane representations in the <Geometry Model> has a <Geometry ID> with a <Geometry ID Control Link>, so that when the lane model is instanced, the instanced lanes can be uniquely identified, and <Same As Geometry Edge> information can be provided to specify which representations actually correspond to the same environmental entity.
