31 // History:
32 // -----------
33 // 1 Aug 2001 MGP Created
34 // 09 Oct 2001 VI Add FindValue with 3 parameters
35 // + NumberOfComponents
36 // 19 Jul 2002 VI Create composite data set for material
37 // 21 Jan 2003 VI Cut per region
38 //
39 // 15 Jul 2009 Nicolas A. Karakatsanis
40 //
41 // - LoadNonLogData method was created to load only the non-logarithmic data from G4EMLOW
42 // dataset. It is essentially performing the data loading operations as in the past.
43 //
44 // - LoadData method was revised in order to calculate the logarithmic values of the data
45 // It retrieves the data values from the G4EMLOW data files but, then, calculates the
46 // respective log values and loads them to seperate data structures.
47 // The EM data sets, initialized this way, contain both non-log and log values.
48 // These initialized data sets can enhance the computing performance of data interpolation
49 // operations
50 //
51 // - BuildMeanFreePathForMaterials method was also revised in order to calculate the
52 // logarithmic values of the loaded data.
53 // It generates the data values and, then, calculates the respective log values which
54 // later load to seperate data structures.
55 // The EM data sets, initialized this way, contain both non-log and log values.
56 // These initialized data sets can enhance the computing performance of data interpolation
57 // operations
58 //
59 // - LoadShellData method was revised in order to eliminate the presence of a potential
60 // memory leak originally identified by Riccardo Capra.
61 // Riccardo Capra Original Comment
62 // Riccardo Capra <capra@ge.infn.it>: PLEASE CHECK THE FOLLOWING PIECE OF CODE
63 // "energies" AND "data" G4DataVector ARE ALLOCATED, FILLED IN AND NEVER USED OR
64 // DELETED. WHATSMORE LOADING FILE OPERATIONS WERE DONE BY G4ShellEMDataSet
65 // EVEN BEFORE THE CHANGES I DID ON THIS FILE. SO THE FOLLOWING CODE IN MY
66 // OPINION SHOULD BE USELESS AND SHOULD PRODUCE A MEMORY LEAK.
