32 // ClassName: G4Material
33 //
34 // Description: Contains material properties
35 //
36 // Class description:
37 //
38 // Is used to define the material composition of Geant4 volumes.
39 // A G4Material is always made of G4Elements. It should has the name,
40 // the list of G4Elements, material density, material state, temperature,
41 // pressure. Other parameters are optional and may be set by the user code
42 // or computed at initialisation.
43 //
44 // There is several ways to construct G4Material:
45 // - from single element;
46 // - from a list of components (elements or other materials);
47 // - from internal Geant4 database of materials
48 //
49 // A collection of constituent Elements/Materials should be defined
50 // with specified weights by fractional mass or atom counts (only for Elements).
51 //
52 // Quantities, with physical meaning or not, which are constant in a given
53 // material are computed and stored here as Derived data members.
54 //
55 // The class contains as a private static member the Table of defined
56 // materials (an ordered vector of materials).
57 //
58 // It is strongly not recommended to delete materials in user code.
59 // All materials will be deleted automatically at the end of Geant4 session.
