32 //
33 // Class description:
34 //
35 // G4PhysicsTable is an utility class for storage of pointers
36 // to G4PhysicsVector containers. It derives all functionalities
37 // of STL vector containers with the addition of few methods for
38 // compatibility with previous implementation based on Rogue-Wave
39 // pointer collections.
40 // The constructor given the 'capacity' of the table, pre-allocates
41 // memory for the specified value by invoking the STL's reserve()
42 // function, in order to avoid reallocation during insertions.
43 // G4PhysicsTable has a vector of boolean which are used
44 // as 'recalc-needed' flags when processes calculate physics tables.
45 // ------------------------------------------------------------
46 //
47 // History:
48 // -------
49 // - First implementation, based on object model of
50 // 2nd December 1995. G.Cosmo
51 // - 1st March 1996, modified. K.Amako
52 // - 24th February 2001, migration to STL vectors. H.Kurashige
53 // - 9th March 2001, added Store/RetrievePhysicsTable. H.Kurashige
54 // - 20th August 2004, added FlagArray and related methods H.Kurashige
