Syntax

public static class EdgeExtensions

Methods

DirectedEdgeId(Graph.EdgeEnumerator)

Returns a directed version of the edge-id. Smaller than 0 if inverted, as-is if not inverted.

Declaration

public static DirectedEdgeId DirectedEdgeId(this Graph.EdgeEnumerator enumerator)

Parameters

Graph.EdgeEnumerator enumerator

Returns

DirectedEdgeId

Remarks

The relationship between a regular edge id and a directed edge id:

• 0 -> 1 forward, -1 backward.
• all other id's are offset by 1 and postive when forward, negative when backward.

GetSourceVertex(Graph.EdgeEnumerator, Int64)

Gets the source vertex.

Declaration

public static uint GetSourceVertex(this Graph.EdgeEnumerator enumerator, long directedEdgeId)

Parameters

Graph.EdgeEnumerator enumerator

System.Int64 directedEdgeId

Returns

System.UInt32

GetTargetVertex(Graph.EdgeEnumerator, Int64)

Gets the target vertex.

Declaration

public static uint GetTargetVertex(this Graph.EdgeEnumerator enumerator, long directedEdgeId)

Parameters

Graph.EdgeEnumerator enumerator

System.Int64 directedEdgeId

Returns

System.UInt32

GetWeight(Graph.EdgeEnumerator, Func<UInt16, Factor>)

Gets the weight for the current edge.

Declaration

public static float GetWeight(this Graph.EdgeEnumerator enumerator, Func<ushort, Factor> getFactor)

Parameters

Graph.EdgeEnumerator enumerator

Func<System.UInt16, Factor> getFactor

Returns

System.Single

GetWeight(Graph.EdgeEnumerator, Func<UInt16, Factor>, out Int16)

Gets the weight for the current edge.

Declaration

public static float GetWeight(this Graph.EdgeEnumerator enumerator, Func<ushort, Factor> getFactor, out short direction)

Parameters

Graph.EdgeEnumerator enumerator

Func<System.UInt16, Factor> getFactor

System.Int16 direction

Returns

System.Single

GetWeight(Graph.EdgeEnumerator, Int64, Func<UInt16, Factor>)

Gets the weight for the given edge.

Declaration

public static float GetWeight(this Graph.EdgeEnumerator enumerator, long edge, Func<ushort, Factor> getFactor)

Parameters

Graph.EdgeEnumerator enumerator

System.Int64 edge

Func<System.UInt16, Factor> getFactor

Returns

System.Single

GetWeight(Graph.EdgeEnumerator, Int64, Func<UInt16, Factor>, out Int16)

Gets the weight for the given edge.

Declaration

public static float GetWeight(this Graph.EdgeEnumerator enumerator, long directedEdgeId, Func<ushort, Factor> getFactor, out short direction)

Parameters

Graph.EdgeEnumerator enumerator

System.Int64 directedEdgeId

Func<System.UInt16, Factor> getFactor

System.Int16 direction

Returns

System.Single

IdDirected(Edge)

Returns a directed version of the edge-id. Smaller than 0 if inverted, as-is if not inverted.

Declaration

public static long IdDirected(this Edge edge)

Parameters

Edge edge

Returns

System.Int64

Remarks

The relationship between a regular edge id and a directed edge id:

• 0 -> 1 forward, -1 backward.
• all other id's are offset by 1 and postive when forward, negative when backward.

IdDirected(Graph.EdgeEnumerator)

Returns a directed version of the edge-id. Smaller than 0 if inverted, as-is if not inverted.

Declaration

public static long IdDirected(this Graph.EdgeEnumerator enumerator)

Parameters

Graph.EdgeEnumerator enumerator

Returns

System.Int64

Remarks

The relationship between a regular edge id and a directed edge id:

• 0 -> 1 forward, -1 backward.
• all other id's are offset by 1 and postive when forward, negative when backward.

MoveToEdge(Graph.EdgeEnumerator, Int64)

Moves to the given directed edge-id.

Declaration

public static void MoveToEdge(this Graph.EdgeEnumerator enumerator, long directedEdgeId)

Parameters

Graph.EdgeEnumerator enumerator

System.Int64 directedEdgeId

MoveToTargetVertex(Graph.EdgeEnumerator, Int64)
