The source of the node.
[Visual Basic .NET] Public ReadOnly Property Source As esriTinNodeSourceType
[C#] public esriTinNodeSourceType Source {get;}
[C++]
HRESULT get_Source(
esriTinNodeSourceType* pSource
);
[C++]
Parameters pSource [out, retval]
pSource is a parameter of type esriTinNodeSourceType*
The source of a node is in reference to where it came from; its origin. An enumeration defines the possibilities:
esriTinDensified - added by the triangulator along a breakline so that it may be Delaunay conforming.
esriTinIntersection - added by the triangulator where breaklines intersect.
esriTinOriginal - a mass point or breakline vertex handed to the triangulator as user data.
esriTinSuperNode - one of 4 nodes added far outside the declared data extent when a TIN is first created.
esriTinUnknown - undefined/unspecified, probably coming from a TIN stored on disk.
TINs do not yet persist node source information. It is only maintained while the TIN is is edit mode. This means after a TIN has been saved to disk, all nodes, except for super nodes, become unknown.
