Detailed Description

template<typename T, typename R = T>
class llvm::StringSwitch< T, R >

A switch()-like statement whose cases are string literals.

The StringSwitch class is a simple form of a switch() statement that determines whether the given string matches one of the given string literals. The template type parameter T is the type of the value that will be returned from the string-switch expression. For example, the following code switches on the name of a color in argv[i]:

Color color = StringSwitch<Color>(argv[i])
  .Case("red", Red)
  .Case("orange", Orange)
  .Case("yellow", Yellow)
  .Case("green", Green)
  .Case("blue", Blue)
  .Case("indigo", Indigo)
  .Cases("violet", "purple", Violet)
  .Default(UnknownColor);
