getCount

public int getCount()
             throws IOException,
                    AutomationException

Number of adjacent edges returned by the NetworkForwardStar object.

Remarks

The Count is the number of adjacent edge elements returned by INetworkForwardStar::QueryAdjacencies. Use this value to iterate over the adjacent elements.

Product Availability

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

Specified by:

getCount in interface INetworkForwardStarAdjacencies

Returns:

The count

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

queryAtJunction

public void queryAtJunction(INetworkJunction junction)
                     throws IOException,
                            AutomationException

Queries the junction element used as the atJunction in the NetworkForwardStar object.

Remarks

The QueryAtJunction method retrieves the junction element used by the INetworkForwardStar::QueryAdjacencies method.

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

Product Availability

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

Specified by:

queryAtJunction in interface INetworkForwardStarAdjacencies

Parameters:

junction - A reference to a com.esri.arcgis.geodatabase.INetworkJunction (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

queryEdge

public void queryEdge(int index,
                      INetworkEdge adjacentEdge,
                      double[] fromPosition,
                      double[] toPosition)
               throws IOException,
                      AutomationException

Queries the adjacent edge element at the specified index.

Remarks

The QueryEdge method returns the edge element that is adjacent to the atJunction at the specified index.

The index values range from 0 to (Count - 1).

The QueryEdge 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.

The fromPosition and toPosition parameters indicate the range of accessible positions (starting from the atJunction) along the network edge element that was queried. The position values can range from 0.0 to 1.0, where 0.0 is at the starting end of the edge element and 1.0 is at the terminating end of the edge element. The fromPosition value will always be less than or equal to the toPosition value, regardless of the Direction property of the edge element. In most cases, the entire edge element will be accessible, so the fromPosition parameter will be returned as 0.0 and the toPosition parameter will be returned as 1.0.

In the case when only a portion of the edge element is accessible, this means the edge has been partially restricted by a call to the INetworkForwardStarEx::AddEdgeRestriction method.

Product Availability

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

Specified by:

queryEdge in interface INetworkForwardStarAdjacencies

Parameters:

index - The index (in)

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

fromPosition - The fromPosition (out: use single element array)

toPosition - The toPosition (out: use single element array)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

queryToJunction

public void queryToJunction(int index,
                            INetworkJunction adjacentJunction,
                            boolean[] isFiltered)
                     throws IOException,
                            AutomationException

For the adjacent edge element at the specified index, queries the junction element opposite of the atJunction.

Remarks

The QueryToJunction method returns the junction element that is opposite the atJunction via the QueryEdge edge element at the specified index.

The index values range from 0 to (Count - 1).

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

Product Availability

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

Specified by:

queryToJunction in interface INetworkForwardStarAdjacencies

Parameters:

index - The index (in)

adjacentJunction - A reference to a com.esri.arcgis.geodatabase.INetworkJunction (in)

isFiltered - The isFiltered (out: use single element array)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

queryTurn

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

Queries the turn element that passes through the fromEdge, the atJunction, and the adjacent edge at the specified index.

Remarks

The QueryTurn method returns the turn element that traverses from the fromEdge through the atJunction to the QueryEdge edge element at the specified index. The QueryTurn method does not always return a turn element -- to determine if a turn element will be returned, call the HasTurn property using the same index value.

The index values range from 0 to (Count - 1).

The QueryTurn 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 INetworkForwardStarAdjacencies

Parameters:

index - The index (in)

adjacentTurn - 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.

isHasTurn

public boolean isHasTurn(int index)
                  throws IOException,
                         AutomationException

Indicates if the adjacent edge at the specified index has a turn.

Specified by:

isHasTurn in interface INetworkForwardStarAdjacencies

Parameters:

                             throws IOException,
                                    AutomationException

Indicates if any of the adjacent edges are restricted due to a turn restriction.

Remarks

The NetworkForwardStarAdjacencies object holds the adjacent network elements that were queried by calling the INetworkForwardStarEx::QueryAdjacencies method.

The HasTurnRestriction property indicates if any of the edges adjacent to the atJunction have not been included in the NetworkForwardStarAdjacencies object due to a turn restriction.

Product Availability

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

Specified by:

isHasTurnRestriction in interface INetworkForwardStarAdjacencies

Returns:

The hasTurnRestriction

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
