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.
