Syntax

public class Edge<TNodeData, TLinkData> : IEdge<Node<TNodeData, TLinkData>, Edge<TNodeData, TLinkData>> where TNodeData : new()
    where TLinkData : new()

Type Parameters

TNodeData

TLinkData

Constructors

Edge()

Initializes a new instance of the Edge<TNodeData, TLinkData> class.

Declaration

public Edge()

Edge(IConnection)

Initializes a new instance of the Edge<TNodeData, TLinkData> class.

Declaration

public Edge(IConnection connection)

Parameters

IConnection connection The connection on which this link is based.

Properties

Connection

Gets the associated IConnection object. If this is a virtual edge this connection is null.

Declaration

public IConnection Connection { get; }

Property Value

IConnection

Id

Gets or sets identifier.

Declaration

public int Id { get; set; }

Property Value

System.Int32

Implements

IEdge<TNode, TLink>.Id

IsDirected

Gets or sets whether there is an intrinsic direction. If not, this means the edge can be traversed in both directions.

Declaration

public bool IsDirected { get; set; }

Property Value

System.Boolean

IsReversed

Gets whether link has been reversed (using the Reverse() method).

Declaration

public bool IsReversed { get; }

Property Value

System.Boolean

IsVirtual

Gets whether this edge represents a logical link rather than one derived from a single connection. For instance, a virtual edge is necessary when multiple connections exist between containers and the working graph needs a single edge for the layout process.

Declaration

public bool IsVirtual { get; }

Property Value

System.Boolean

NumberOfVirtualNodes

Gets or sets the number of virtual nodes which have been inserted during the process of breaking layer-crossing links. This is specific to the Sugiyama layout.

Declaration

public int NumberOfVirtualNodes { get; set; }

Property Value

System.Int32

Points

Gets or sets the points defining the link.

Declaration

public IList<Point> Points { get; set; }

Property Value

System.Collections.Generic.IList<System.Windows.Point>

Remarks

This also defines eventually the IConnection visual if it's a polyline or some other multi-point visual.

PropertyBag

Gets or sets the dictionary of runtime/layout properties.

Declaration

public Dictionary<object, object> PropertyBag { get; set; }

Property Value

System.Collections.Generic.Dictionary<System.Object, System.Object>

SegmentIndex

Gets or sets index of the segment.

Declaration

public int SegmentIndex { get; set; }

Property Value

System.Int32

Sink

Gets the destination (target, end) node of this link.

Declaration

public Node<TNodeData, TLinkData> Sink { get; set; }

Property Value

Node<TNodeData, TLinkData>

Implements

IEdge<TNode, TLink>.Sink

Source

Gets the source (origin, start) node of this link.

Declaration

public Node<TNodeData, TLinkData> Source { get; set; }

Property Value

Node<TNodeData, TLinkData>

Implements

IEdge<TNode, TLink>.Source

Weight

Gets the weight of this link.

Declaration

public double Weight { get; set; }

Property Value

System.Double

Implements

IEdge<TNode, TLink>.Weight

Methods

Clone()

Returns a (shallow) clone of this link.

Declaration

public Edge<TNodeData, TLinkData> Clone()

Returns

Edge<TNodeData, TLinkData> A clone of this link.

Implements

IEdge<TNode, TLink>.Clone()

Remarks

The following properties are being cloned:

• The identifier (Id)
• The weight (Weight)
• The segment index (SegmentIndex)
• The points (Points).

GetBounds()

Gets the bounding rectangle of this entity.

Declaration

public Rect GetBounds()

Returns

System.Windows.Rect

GetComplementaryNode(INode<Node<TNodeData, TLinkData>, Edge<TNodeData, TLinkData>>)

Returns the opposite or complementary node of the given one.

Declaration

public Node<TNodeData, TLinkData> GetComplementaryNode(INode<Node<TNodeData, TLinkData>, Edge<TNodeData, TLinkData>> node)

Parameters

INode<Node<TNodeData, TLinkData>, Edge<TNodeData, TLinkData>> node The node whose complement is looked for.

Returns

Node<TNodeData, TLinkData> null if the node is not part of this link, otherwise the opposite or complementary node with respect to this link.

Implements

IEdge<TNode, TLink>.GetComplementaryNode(INode<TNode, TLink>)

GetOppositeNode(Node<TNodeData, TLinkData>)

Returns the node at the opposite end of the link.

Declaration

public Node<TNodeData, TLinkData> GetOppositeNode(Node<TNodeData, TLinkData> node)

Parameters

Node<TNodeData, TLinkData> node The a Node.

Returns

Node<TNodeData, TLinkData>

Reverse()

Reverses the direction of this link.

Declaration

public void Reverse()

Implements

IEdge<TNode, TLink>.Reverse()

SetPoints(IEnumerable<Point>)

Sets the control points (Points) of this link.

Declaration

public void SetPoints(IEnumerable<Point> points)

Parameters

System.Collections.Generic.IEnumerable<System.Windows.Point> points The points defining this link.
