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