| 37 | // 02 Dec. 1995, G.Cosmo : Structure created based on object model |
---|
| 38 | // 03 Mar. 1996, K.Amako : Implemented the 1st version |
---|
| 39 | // 01 Jul. 1996, K.Amako : Hidden bin from the user introduced |
---|
| 40 | // 12 Nov. 1998, K.Amako : A bug in GetVectorLength() fixed |
---|
| 41 | // 11 Nov. 2000, H.Kurashige : use STL vector for dataVector and binVector |
---|
| 42 | // 18 Jan. 2001, H.Kurashige : removed ptrNextTable |
---|
| 43 | // 09 Mar. 2001, H.Kurashige : added G4PhysicsVector type |
---|
[850] | 44 | // 05 Sep. 2008, V.Ivanchenko : added protections for zero-length vector |
