SearchEdges Method (TinDataset)

In This Topic

Retrieves the edges in the TIN that satisfy the criteria set in the . If no filter is set, all single edges that intersect the data extent will be retrieved. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

Visual Basic (Declaration)
C#

Public Function SearchEdges( _
   ByVal filter As TinEdgeFilter _
) As TinEdgeCursor

public TinEdgeCursor SearchEdges( 
   TinEdgeFilter filter
)

Parameters

filter: Filter by parameters. See TinEdgeFilter. If null, then all single edges that intersect the data extent will be retrieved.

Return Value

A TinEdgeCursor.

Exceptions

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run

Remarks

To ensure maximum robustness, callers should explicitly dispose of the returned TinEdgeCursor in either a using statement or a finally block.

Example

Search for TIN Edges

{
  // search all single edges that intersect the data extent
  using (ArcGIS.Core.Data.Analyst3D.TinEdgeCursor edgeCursor = tinDataset.SearchEdges(null))
  {
    while (edgeCursor.MoveNext())
    {
      using (ArcGIS.Core.Data.Analyst3D.TinEdge edgeCurrent = edgeCursor.Current)
      {
        // do something with the edge
      }
    }
  }

  // search within an extent
  ArcGIS.Core.Data.Analyst3D.TinEdgeFilter edgeFilter = new ArcGIS.Core.Data.Analyst3D.TinEdgeFilter();
  edgeFilter.FilterEnvelope = envelope;
  using (ArcGIS.Core.Data.Analyst3D.TinEdgeCursor edgeCursor = tinDataset.SearchEdges(edgeFilter))
  {
    while (edgeCursor.MoveNext())
    {
      using (ArcGIS.Core.Data.Analyst3D.TinEdge edgeCurrent = edgeCursor.Current)
      {
        // do something with the edge
      }
    }
  }

  // search all "inside" edges
  edgeFilter = new ArcGIS.Core.Data.Analyst3D.TinEdgeFilter();
  edgeFilter.FilterType = ArcGIS.Core.Data.Analyst3D.TinFilterType.InsideDataArea;
  using (ArcGIS.Core.Data.Analyst3D.TinEdgeCursor edgeCursor = tinDataset.SearchEdges(edgeFilter))
  {
    while (edgeCursor.MoveNext())
    {
      using (ArcGIS.Core.Data.Analyst3D.TinEdge edgeCurrent = edgeCursor.Current)
      {
        // do something with the edge
      }
    }
  }

  // search for hard edges
  edgeFilter = new ArcGIS.Core.Data.Analyst3D.TinEdgeFilter();
  edgeFilter.FilterByEdgeType = true;
  edgeFilter.EdgeType = ArcGIS.Core.Data.Analyst3D.TinEdgeType.HardEdge;
  using (ArcGIS.Core.Data.Analyst3D.TinEdgeCursor edgeCursor = tinDataset.SearchEdges(edgeFilter))
  {
    while (edgeCursor.MoveNext())
    {
      using (ArcGIS.Core.Data.Analyst3D.TinEdge edgeCurrent = edgeCursor.Current)
      {
        // do something with the edge
      }
    }
  }
}
