NConnectionPoint Class

In This Topic

The NConnectionPoint abstract class represents a point, which can be a member of a connection. It serves as base class for ports and plugs.

'Usage
 
Dim instance As NConnectionPoint

Remarks

Each connection point has the potential to be connected to only one Inward Port. The Inward Port to which the connection point is currently connected is obtained from the InwardPort property.

When a connection point is connected it creates a dependency, between its shape and the inward port shape. When the inward port shape is changed the dependent shapes are automatically updates. The type of dependency update depends on the type of connected point. For example: start and end plugs will update the shape start and end points, outward ports will translate (rotate) the shape to match the inward port location and direction.
