Read-only property ElementType Type of this network element.
Read-only property OID Object ID of the object corresponding to this network element.
Method QueryEdge Queries the index'th network edge element adjacent to this network junction element.
Method QueryPoint Queries the point object corresponding to this network junction element.
Method QueryTurn Queries the index'th network turn element anchored at this network junction element.
Read-only property SourceID ID of the network dataset source from which this network element was derived.
Read-only property TurnCount Number of network turn elements anchored at this network junction.

INetworkJunction.AttributeValue Property

Value of this network element for the given network attribute ID.

Public Function get_AttributeValue ( _
    ByVal AttributeID As Integer _
) As Object
public object get_AttributeValue (
    int AttributeID
);

INetworkJunction.AttributeValueAtTime Property

Value of this network element for the given network attribute ID and local time.

Public Function get_AttributeValueAtTime ( _
    ByVal AttributeID As Integer, _
    ByVal localTime As DateTime, _
    ByVal timeUsage As esriNetworkTimeUsage _
) As Object
public object get_AttributeValueAtTime (
    int AttributeID,
    DateTime localTime,
    esriNetworkTimeUsage timeUsage
);

INetworkJunction.AttributeValueByName Property

Value of this network element for the given network attribute name.

Public Function get_AttributeValueByName ( _
    ByVal AttributeName As String _
) As Object
public object get_AttributeValueByName (
    string AttributeName
);

INetworkJunction.EdgeCount Property

Number of network edge elements adjacent to this network junction element.

Public ReadOnly Property EdgeCount As Integer
public int EdgeCount {get;}

Remarks

The EdgeCount is the number of adjacent edge elements leaving this junction.

INetworkJunction.EID Property

Element ID for this network element.

Public ReadOnly Property EID As Integer
public int EID {get;}

INetworkJunction.ElementType Property

Type of this network element.

Public ReadOnly Property ElementType As esriNetworkElementType
public esriNetworkElementType ElementType {get;}

INetworkJunction.OID Property

Object ID of the object corresponding to this network element.

Public ReadOnly Property OID As Integer
public int OID {get;}

INetworkJunction.QueryEdge Method

Queries the index'th network edge element adjacent to this network junction element.

Public Sub QueryEdge ( _
    ByVal Index As Integer, _
    ByVal leavingJunction As Boolean, _
    ByVal Edge As INetworkEdge _
)
public void QueryEdge (
    int Index,
    bool leavingJunction,
    INetworkEdge Edge
);

Remarks

The QueryEdge method retrieves the edge element adjacent to this junction at the specified index. The index values range from 0 to (EdgeCount - 1).

The leavingJunction parameter determines in which travel direction the edge element is returned. If the leavingJunction parameter is True, then the edge element returned is the element that travels in the direction away from the junction.

This method requires an instantiated NetworkEdge object to be passed in as a parameter. You can create an empty NetworkEdge object by using the INetworkQuery::CreateNetworkElement method.

INetworkJunction.QueryPoint Method

Queries the point object corresponding to this network junction element.

Public Sub QueryPoint ( _
    ByVal point As IPoint _
)
public void QueryPoint (
    IPoint point
);

Remarks

The QueryPoint method retrieves the Point geometry associated with this junction element.

This method requires an instantiated Pointobject to be passed in as a parameter.

On an SDC network dataset, QueryPoint returns an empty Point object for junction elements that do not connect to any edges (i.e., have an EdgeCount of zero).

INetworkJunction.QueryTurn Method

Queries the index'th network turn element anchored at this network junction element.

Public Sub QueryTurn ( _
    ByVal Index As Integer, _
    ByVal Turn As INetworkTurn _
)
public void QueryTurn (
    int Index,
    INetworkTurn Turn
);

Remarks

The QueryTurn method retrieves the turn element anchored to this junction at the specified index. A turn element is anchored at a junction if the last two edges of the turn pass through the junction. The index values range from 0 to (TurnCount - 1).

This method requires an instantiated NetworkTurn object to be passed in as a parameter. You can create an empty NetworkTurn object by using the INetworkQuery::CreateNetworkElement method.

INetworkJunction.SourceID Property

ID of the network dataset source from which this network element was derived.

Public ReadOnly Property SourceID As Integer
public int SourceID {get;}

INetworkJunction.TurnCount Property

Number of network turn elements anchored at this network junction.

Public ReadOnly Property TurnCount As Integer
public int TurnCount {get;}

Remarks

The TurnCount is the number of turn elements that are anchored to this junction. A turn element is anchored at a junction if the last two edges of the turn pass through the junction.
