'Usage
 
Dim instance As NPortCollection

[System.ComponentModel.Editor(Nevron.Diagram.Editors.NDiagramElementContainerTypeEditor, System.Drawing.Design.UITypeEditor)]
[System.Xml.Serialization.XmlInclude(Nevron.Diagram.NLayerCollection)]
[System.Serializable()]
public class NPortCollection : NDiagramElementCollection, INContextMenuEditable, INDiagramElement, INDiagramElementComposite, INDiagramElementContainer, INDiagramElementReferenceHolder, INInvalidatable, INMeasurements, INPaintable, INVisible, INZOrderable, Nevron.Dom.INAttributeContainer, Nevron.Dom.INAttributeObserver, Nevron.Dom.INElement, Nevron.Dom.INElementComposite, Nevron.Dom.INElementContainer, Nevron.Dom.INHistoryCallback, Nevron.Dom.INIdentifiable, Nevron.Dom.INNode, Nevron.Dom.INNodeComposite, Nevron.Dom.INNodeContainer, Nevron.Dom.INUniquelyIdentifiable, Nevron.INReferenceHolder, Nevron.INReferenceProvider

Remarks

The NPortCollection provides a two types of default ports: a default inward port and a default outward port.

The default inward port is controlled by the DefaultInwardPortUniqueId property. When set to Guid.Empty the the DefaultInwardPort property will return the first inward port in the collection. The default inward port is used in implicit connections when the inward port in the connection is not explicitly specified (e.g. in the FromShape, ToShape and OutwardShape property setters)

Similarly the default outward port is controlled by the DefaultOutwardPortUniqueId property. When set to Guid.Empty the the DefaultOutwardPort property will return the first outward port in the collection. The default outward port is used in implicit connections when the outward port in the connection is not explicitly specified (e.g. in the OutwardShape property setter)

Since the default ports are referenced by their ids, the NPortCollection class implements the INDiagramElementReferenceHolder interface.
