NPort Class

In This Topic

The NPort class represents a connection point, which can be anchored to a specific parameter of the shape to which they belong or to an aggregated model, which the shape contains.

'Declaration

'Usage
 
Dim instance As NPort

[System.Xml.Serialization.XmlInclude(Nevron.Diagram.NBoundsPort)]
[System.Serializable()]
public abstract class NPort : NConnectionPoint, INContextMenuEditable, INDiagramElement, INDiagramElementReferenceHolder, INHitTestable, INInvalidatable, INMeasurements, INPaintable, INTranslatable, INZOrderable, Nevron.Dom.INAttributeContainer, Nevron.Dom.INAttributeObserver, Nevron.Dom.INElement, Nevron.Dom.INHistoryCallback, Nevron.Dom.INIdentifiable, Nevron.Dom.INNode, Nevron.Dom.INUniquelyIdentifiable, Nevron.INReferenceHolder, Nevron.INReferenceProvider

Remarks

The Type property of the port defines much of the port behavior. It can take the following values:

Inward ports cannot be connected. However multiple plugs and outward ports of other shapes can be connected to an inward port.
Outward ports can be connected to inward ports. Plugs cannot be connected to outward ports. Only one outward port of a shape can be connected at time. This means that whenever an outward port is connected, both plugs and the currently connected outward port (if any) are automatically disconnected.
Behaves as an inward and outward port.
