Node Type

Specifies characteristics common to all Nodes of a given type. A class node, for example, has three compartments, sharp corners a certain border style, etc. For now, to support a different visual style for a class node, let’s say, you would need to define a new node/diagram type combination (UML class on a UML class diagram type vs. Shlaer-Mellor class on a Shlaer-Mellor class diagram type), for example). Since, most diagrams we are considering have notational variation in the Connector Types and not the Node Types, we’re baking in the visual characteristics of a Node Type for now and making it flexible for Connector Types.

Attributes

Name

A name like “class”, “state”, “imported class”, “domain”, etc.

Type: Node Type Name, based on Name

Default size

Initial assumption about a Node size.

Max Size

Node may not be drawn larger than this size.
