Last change on this file since c38826 was 88b400, checked in by Frederik Heber <heber@…>, 14 years ago

converted #define's to enums, consts and typedefs [Meyers, "Effective C++", item 1].

basic changes:

  • #define bla 1.3 -> const double bla = 1.3
  • #define bla "test" -> const char * const bla = "test
  • use class specific constants! (HULLEPSILON)

const int Class::bla = 1.3; (in .cpp)
static const int bla; (in .hpp inside class private section)

  • "enum hack": #define bla 5 -> enum { bla = 5 };
    • if const int bla=5; impossible
    • e.g. necessary if constant is used in array declaration (int blabla[bla];)

details:

  • new file defs.cpp where const double reside in and are referenced by extern "C" const double
  • joiner.cpp: main() had to be changed due to concatenation of two #define possible, of two const char * not
  • class specific constants: HULLEPSILON, BONDTHRESHOLD, SPHERERADIUS
  • extended GetPathLengthonCircumCircle to additional parameter HULLEPSILON
  • Property mode set to 100644
