[vtk-developers] hast table in VTK

[Moreland, Kenneth]

My thought was that the hash table would just be a collection of
vtkObjectBase.  In this sense it would be just keys, no values (i.e. a
set, not a map).

My intension was an interface sort-of like that for Java's hashtable.
When a key is inserted, the hashcode is retrieved directly from a method
on that key.  This would only be possible if vtkObjectBase implemented
virtual hashcode methods.
