 Coding Standards
 ================

 additional to the ALICE C++ Coding Conventions 

 1. Ordering of headers:
    1. Ali*
    2. G4*
    3. other packages (CLHEP, ODBMS, ROOT, ...)
    4. system (eg. <iostrem.h>)      

 2. Use G4 basic type instead of "raw" types:
    G4int, G4double, G4bool, G4String, ...
       
 3. Inline fuctions:
    When implementation of inline methods is within two lines,
    put it in the header file after the class
    declaration in the header file (*.hh or *.ddl);
    otherwise put it in a separated *.cc file.  
    
 4. Declare member functions that should not
    change class member data as const.   
    
 5. Re-declare virtual member functions in a derived class
    with a keyword virtual.
    
 6. Header file:
    Place each section in the class declarations 
    (public, protected, private) in this order:
    // constructors 
    // destructor 
    // operators
    // static methods
    // methods
    // set methods
    // get methods
    // static data members
    // data members
    Use comment line for all sections except for
    constructors and destructors.
    
 7. Implementation file:
    declare class definitions in this order:
    // static data members
    // static methods
    // constructors
    // destructors
    // methods 
    Private definitions should be declared first,
    then protected and public.
    
 8. Exception/Warning:
    Use AliGlobal::Exception()/Warning(); (or TG4Global in g4mc)
    use this form of text:
    class_name::method_name: exception/warning_text    

 9. Style:
    Standard indention:  2 spaces;
    Max. line length:   80 characters;  

 Recomendations:
      - default constructor - protected in suitable cases
        (to prevent from creation of invalid objects)
      - always provide copy constructor and assignement operator
        for a class with pointer-type data member(s)
