getEdgeCount

public int getEdgeCount()
                 throws IOException,
                        AutomationException

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

Remarks

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

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Specified by:

getEdgeCount in interface INetworkJunction

Returns:

The adjacentEdgeCount

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getTurnCount

public int getTurnCount()
                 throws IOException,
                        AutomationException

Number of network turn elements anchored at this network junction.

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.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Specified by:

getTurnCount in interface INetworkJunction

Returns:

The turnCount

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

queryEdge

public void queryEdge(int index,
                      boolean leavingJunction,
                      INetworkEdge edge)
               throws IOException,
                      AutomationException

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

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.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Specified by:

queryEdge in interface INetworkJunction

Parameters:

index - The index (in)

leavingJunction - The leavingJunction (in)

edge - A reference to a com.esri.arcgis.geodatabase.INetworkEdge (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

queryTurn

public void queryTurn(int index,
                      INetworkTurn turn)
               throws IOException,
                      AutomationException

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

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.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Specified by:

queryTurn in interface INetworkJunction

Parameters:

index - The index (in)

turn - A reference to a com.esri.arcgis.geodatabase.INetworkTurn (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

queryPoint

public void queryPoint(IPoint point)
                throws IOException,
                       AutomationException

Queries the point object corresponding to this network junction element.

Remarks

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

This method requires an instantiated Point object 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).

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Specified by:

queryPoint in interface INetworkJunction

Parameters:

point - A reference to a com.esri.arcgis.geometry.IPoint (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
