Slice constant definitions map to corresponding Objective?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:
Objective-C
static const BOOL EXAppendByDefault = YES;
static const ICEByte EXLowerNibble = 15;
static NSString * const EXAdvice = @"Don't Panic!";
static const ICEShort EXTheAnswer = 42;
static const ICEDouble EXPI = 3.1416;
typedef enum {
EXApple, EXPear, EXOrange
} EXFruit;
static const EXFruit EXFavoriteFruit = EXPear;
All constants are initialized directly in the generated 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.
