MoveNext Method (TinNodeCursor)

In This Topic

Advances to the next TinNode in this TinNodeCursor. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public bool MoveNext()

Public Function MoveNext() As Boolean

Return Value

true if the cursor has successfully advanced to the next node; false if the cursor has passed the end of the collection.

Exceptions

Exception	Description
ArcGIS.Core.Data.Exceptions.GeodatabaseException	A geodatabase-related exception has occurred.

Remarks

If MoveNext() returns true, a TinNode object is created. Even if this node (Current) is not otherwise needed, it should be properly disposed through a call to System.IDisposable.Dispose or with the use of a using statement.

Example

Search for TIN Nodes

// search all nodes
using (ArcGIS.Core.Data.Analyst3D.TinNodeCursor nodeCursor = tinDataset.SearchNodes(null))
{
  while (nodeCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.TinNode node = nodeCursor.Current)
    {

    }
  }
}

// search within an extent
ArcGIS.Core.Data.Analyst3D.TinNodeFilter nodeFilter = new ArcGIS.Core.Data.Analyst3D.TinNodeFilter();
nodeFilter.FilterEnvelope = envelope;
using (ArcGIS.Core.Data.Analyst3D.TinNodeCursor nodeCursor = tinDataset.SearchNodes(nodeFilter))
{
  while (nodeCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.TinNode node = nodeCursor.Current)
    {

    }
  }
}

// search all "inside" nodes
nodeFilter = new ArcGIS.Core.Data.Analyst3D.TinNodeFilter();
nodeFilter.FilterType = ArcGIS.Core.Data.Analyst3D.TinFilterType.InsideDataArea;
using (ArcGIS.Core.Data.Analyst3D.TinNodeCursor nodeCursor = tinDataset.SearchNodes(nodeFilter))
{
  while (nodeCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.TinNode node = nodeCursor.Current)
    {

    }
  }
}

// search for super nodes only
nodeFilter = new ArcGIS.Core.Data.Analyst3D.TinNodeFilter();
nodeFilter.FilterEnvelope = tinDataset.GetSuperNodeExtent();
nodeFilter.SuperNode = true;
using (ArcGIS.Core.Data.Analyst3D.TinNodeCursor nodeCursor = tinDataset.SearchNodes(nodeFilter))
{
  while (nodeCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.TinNode node = nodeCursor.Current)
    {

    }
  }
}
