Component definition diagram (IDL code)
A Component Definition Diagram allows you to create the following items.
• Components
• Connectors
• Port Types
• Interfaces
Through Generalizations you can define inheritance between two Components, two Connectors, two Port Types and two Interfaces.
All Component Definition Diagrams are shown in the 
IDL Elements pane - expand the Component Definition Diagram folder.
IDL Elements pane - expand the Component Definition Diagram folder.A Component Definition Diagram is based on a UML Text Diagram.
A Component Definition Diagram can show the following IDL items.
Component
To create a Component: click the 
Component button, and then click in free space on the diagram.
Component button, and then click in free space on the diagram.To add an existing Component to the diagram: drag the Component from an appropriate pane to free space on the diagram.
Note that a Component's view options are set through the Class entry.
Connector
To create a Connector: click the 
Connector button, and then click in free space on the diagram.
Connector button, and then click in free space on the diagram.To add an existing Connector to the diagram: drag the Connector from an appropriate pane to free space on the diagram.
Note that a Connector's view options are set through the Class entry.
Generalization (UML item)
You can create a Generalization between two Components, two Connectors, two Interfaces or two Port Types.
To create a Generalization: click the 
Generalization button, click the sub item, and then click the super item.
Generalization button, click the sub item, and then click the super item.To add missing Generalizations to the diagram: right-click an item or the diagram background, point to Populate, and then click Inheritance.
Interface
To create a Connector: click the 
Interface button, and then click in free space on the diagram.
Interface button, and then click in free space on the diagram.To add an existing Interface to the diagram: drag the Interface from an appropriate pane to free space on the diagram.
Note that an Interface's view options are set through the Interface entry.
Port Type
To create a Port Type: click the 
Port Type button, and then click in free space on the diagram.
Port Type button, and then click in free space on the diagram.To add an existing Port Type to the diagram: drag the Port Type from an appropriate pane to free space on the diagram.
Note that a Port Type's view options are set through the Class entry.
