Here are the sample constant definitions once more:
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:
Java Compat
public interface AppendByDefault
{
boolean value = true;
}
public interface LowerNibble
{
byte value = 15;
}
public interface Advice
{
String value = "Don't Panic!";
}
public interface TheAnswer
{
short value = 42;
}
public interface PI
{
double value = 3.1416;
}
public interface FavoriteFruit
{
Fruit value = Fruit.Pear;
}
As you can see, each Slice constant is mapped to a Java interface with the same name as the constant. The interface contains a member named value that holds the value of the constant.
Slice string literals that contain non-ASCII characters or universal character names are mapped to Java string literals with universal character names. For example:
Slice
const string Egg = "œuf"; const string Heart = "c\u0153ur"; const string Banana = "\U0001F34C";
is mapped to:
Java Compat
public interface Egg
{
String value = "\u0153uf";
}
public interface Heart
{
String value = "c\u0153ur";
}
public interface Banana
{
String value = "\ud83c\udf4c";
}
