Overview

The ComponentInstance class is used to represent component instances of a component definition or components that have been dragged from the Component Browser and placed (thus, instanced) within the Model. Therefore, the ComponentInstance class contains a reference to a corresponding ComponentDefinition object and a Transformation object (which contains the location of the component in the Drawing Window).
