6 // look-up tables for fast access to volumes :
7 // 1) the look-up table mapping unique volume ids to symbolic volume names
8 // 2) the look-up table mapping unique volume ids to TGeoPNEntries
9 // this allows to access directly the functionality of the physical node
10 // associated to a given alignable volume by means of its index
