IODLinkShape Class

class IODLinkShape: public IODObject

The link shape interface defines a set of methods used by the  CODLinkComponent class for positioning a child component to dock with its connected symbols. This interface is mixed into classes derived from  CODComponent so that any type of shape (not just lines) can be used for links. The link shape defines a head and tail point that correspond to the head and tail ports of a link. The method Dock adjusts the shape so that the head and tail points are positioned over the given ports. The UpdateVertex method is called to update the shape when a vertex is modified. The GetComponent provides a type-safe way to cast the link shape to a CODComponent object.

Defined in: OdLinkShape.h
