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

Visual Basic (Declaration)
C#

Public Function MoveNext() As Boolean

public bool MoveNext()

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 that intersect the data extent
  using (ArcGIS.Core.Data.Analyst3D.TinNodeCursor nodeCursorsearch = tinDataset.SearchNodes(null))
  {
    while (nodeCursor.MoveNext())
    {
      using (ArcGIS.Core.Data.Analyst3D.TinNode nodeCurrent = nodeCursor.Current)
      {
        // do something with the node
      }
    }
  }

  // search within an extent
  ArcGIS.Core.Data.Analyst3D.TinNodeFilter nodeFilter = new ArcGIS.Core.Data.Analyst3D.TinNodeFilter();
  nodeFilter.FilterEnvelope = envelope; //or use any other appropriate envelope
  using (ArcGIS.Core.Data.Analyst3D.TinNodeCursor nodeCursorSearch = tinDataset.SearchNodes(nodeFilter))
  {
    while (nodeCursor.MoveNext())
    {
      using (ArcGIS.Core.Data.Analyst3D.TinNode nodeCurrent = nodeCursor.Current)
      {
        // do something with the node
      }
    }
  }

  // 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 nodeCursorSearch = tinDataset.SearchNodes(nodeFilter))
  {
    while (nodeCursor.MoveNext())
    {
      using (ArcGIS.Core.Data.Analyst3D.TinNode nodeCurrent = nodeCursor.Current)
      {
        // do something with the node
      }
    }
  }

  // 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 nodeCursorSearch = tinDataset.SearchNodes(nodeFilter))
  {
    while (nodeCursor.MoveNext())
    {
      using (ArcGIS.Core.Data.Analyst3D.TinNode nodeCurrent = nodeCursor.Current)
      {
        // do something with the node
      }
    }
  }
}
