Method Detail

esri_getSource

int esri_getSource()
                   throws IOException,
                          AutomationException

The source of the node.

Product Availability

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

Returns:

A com.esri.arcgis.geodatabase.esriTinNodeSourceType constant

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getDegree

int getDegree(boolean bEnforcedEdgesOnly)
              throws IOException,
                     AutomationException

The degree of the node.

Product Availability

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

Parameters:

bEnforcedEdgesOnly - The bEnforcedEdgesOnly (in)

Returns:

The pDegree

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

isOnDomainBoundary

boolean isOnDomainBoundary()
                           throws IOException,
                                  AutomationException

Indicates if the specified node is on domain's boundary.

Description

The TIN's domain is the same thing as its interpolation zone. IsOnDomainBoundary returns TRUE if the node is on this boundary, separating data from nodata areas.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Returns:

The pbIsOn

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

queryAdjacentNodeIndices

void queryAdjacentNodeIndices(ILongArray pNodes)
                              throws IOException,
                                     AutomationException

Returns all nodes connecting to the node.

Description

Returns indices for nodes adjacent to the given node. These are its direct neighbors which are connected by triangle edges.

The passed object that implements ILongArray must have already been instantiated.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Parameters:

pNodes - A reference to a com.esri.arcgis.system.ILongArray (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

queryIncidentEdgeIndices

void queryIncidentEdgeIndices(ILongArray pEdges)
                              throws IOException,
                                     AutomationException

Returns all edges sharing the node.

Description

This populates a LongArray with the indices of edges that surround the node.

The passed LongArray must already have been instantiated.

A single edge interpretation is used. This is where edges between adjacent triangles are shared.

Only edges that have their from node in common with the specified node are returned. Because of this, some boundary edges incident to super nodes will have no representation.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Parameters:

pEdges - A reference to a com.esri.arcgis.system.ILongArray (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

queryIncidentTriangleIndices

void queryIncidentTriangleIndices(ILongArray pTriangles)
                                  throws IOException,
                                         AutomationException

Returns all triangles sharing the node.

Description

Returns indices for triangles incident to the node.

The passed object that implements ILongArray must have already been instantiated.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Parameters:

pTriangles - A reference to a com.esri.arcgis.system.ILongArray (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

incidentTriangle

ITinTriangle incidentTriangle()
                              throws IOException,
                                     AutomationException

Returns any triangle having the node as one of it's vertices.

Description

Returns one of the triangles that is incident to the node. There is no fixed rule to determine which triangle it will be. You are just assured it will be one that is defined, in part, by the node.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Returns:

A reference to a com.esri.arcgis.geodatabase.ITinTriangle

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

incidentTriangleIndex

int incidentTriangleIndex()
                          throws IOException,
                                 AutomationException

Returns the index of any triangle having the node as one of it's vertices.

Description

Returns the index for one of the triangles incident to the node. There is no fixed rule to determine which triangle it will be. You are just assured it will be one that is defined, in part, by the node.
