Provides access to members that control the graphic sub-link.


A sublink is a link that exists as part of another link. It connects one node on link to one of its related link’s extremity node or connects two nodes on links. Sublinks are completely dependent on the link they are related to. Selecting and moving a link automatically selects and moves its sublinks. The destruction of the link causes the automatic destruction of its sublinks. As with links, sublinks exist only in run time. The common properties of a sublink are stored and defined by its related sublink type.

Defining nodes on links and sublinks for your links is often useful when you have to graphically display a line that is composed by several different parts. For example, in the electrical world, there are electrical lines that combine an overhead part and an underground part along their path route. In this case, it could be useful to graphically distinguish the overhead part from the underground one using sublinks and nodes on links.
