Slice constant definitions map to corresponding C++ constant definitions. For example:
Slice
const bool AppendByDefault = true;
const byte LowerNibble = 0x0f;
const string Advice = "Don't Panic!";
const short TheAnswer = 42;
const double PI = 3.1416;
enum Fruit { Apple, Pear, Orange };
const Fruit FavoriteFruit = Pear;
Here are the generated definitions for these constants:
C++
const bool AppendByDefault = true;
const Ice::Byte LowerNibble = 15;
const std::string Advice = "Don't Panic!";
const Ice::Short TheAnswer = 42;
const Ice::Double PI = 3.1416;
enum Fruit { Apple, Pear, Orange };
const Fruit FavoriteFruit = Pear;
All constants are initialized directly in the header file, so they are compile-time constants and can be used in contexts where a compile-time constant expression is required, such as to dimension an array or as the case label of a switch statement.
