30 //
31 // Class description:
32 //
33 // A node in the smart voxel hierarchy - a `slice' of space along a given
34 // axis between given minima and maxima. Note that the node is not aware
35 // of its position - this information being available/derivable by the
36 // node's owner(s) (voxelheaders).
37 //
38 // Member Data:
39 //
40 // G4int fminEquivalent
41 // G4int fmaxEquivalent
42 // - Min and maximum nodes with same contents. Set by constructor
43 // and set methods.
44 // std::vector<G4int> fcontents
45 // - Vector of no.s of volumes inside the node.
46 
47 // History:
48 // 18.04.01 G.Cosmo Migrated to STL vector
49 // 12.07.95 P.Kent Initial version
