36 | // History: |
---|
37 | // 02 Dec. 1995, G.Cosmo : Structure created based on object model |
---|
38 | // 15 Feb. 1996, K.Amako : Implemented the 1st version |
---|
39 | // 01 Jul. 1996, K.Amako : Hidden bin from the user introduced |
---|
40 | // 26 Sep. 1996, K.Amako : Constructor with only 'bin size' added |
---|
41 | // 11 Nov. 2000, H.Kurashige : use STL vector for dataVector and binVector |
---|
42 | // 9 Mar. 2001, H.Kurashige : added PhysicsVector type and Retrieve |
---|
43 | // 05 Sep. 2008, V.Ivanchenko : added protections for zero-length vector |
---|
44 | // 19 Jun. 2009, V.Ivanchenko : removed hidden bin |
