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

C#
Visual Basic (Declaration)

public TinEdgeCursor SearchEdges( 
   TinEdgeFilter filter
)

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

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 edge = edgeCursor.Current)
    {

    }
  }
}

// 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 edge = edgeCursor.Current)
    {

    }
  }
}

// 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 edge = edgeCursor.Current)
    {

    }
  }
}

// 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 edge = edgeCursor.Current)
    {

    }
  }
}
