java.lang.Object com.esri.arcgis.geodatabaseextensions.TerrainBlobReader
public class TerrainBlobReader
Esri Terrain blob reader.
TerrainBlobReader is an object used to access terrain/LIDAR related attributes packed into binary large objects (BLOBs). These BLOBs are created by the TerrainLasDataImporter, TerrainAsciiDataImporter, or the TerrainBlobWriter as a means of storing per vertex attribution for points clustered into multipoint shapes.
Constructor Summary | |

public void setEmpty() throws IOException, AutomationException
SetEmpty allows developers to release resources (e.g., memory and other objects) held by the reader at any time, rather than having to wait until the reader goes out of its scope.

IOException
- If there are interop problems.
AutomationException
- If the ArcObject component throws an exception.public boolean isKnownBlob(IMemoryBlobStream pBlob) throws IOException, AutomationException
IsKnownBlob returns TRUE if the BLOB is recognized as a supported type as created by the TerrainLasDataImporter or the TerrainBlobWriter.

pBlob
- A reference to a com.esri.arcgis.system.IMemoryBlobStream (in)
IOException
- If there are interop problems.
AutomationException
- If the ArcObject component throws an exception.public void setBlob(IMemoryBlobStream pBlob) throws IOException, AutomationException
SetBlob is used to assign a reference for a compatible BLOB to the TerrainBlobReader for interpretation.
Notes
- The BLOB referenced must be a compatible type. These include BLOBs made by the TerrainBlobWriter and the TerrainLasDataImporter.
- If you're unsure of compatibility you can test it using ITerrainBlobReader.IsKnownBlob.

GetValue returns the nth value in the BLOB. The index value that's passed, in the context of reading attributes for terrain points, is the point ID which should be stored for each vertex of the multipoint which is paired with the BLOB being read.
