Macro Definition Documentation

#define STRING_SWITCH	(		str,
			...
	)

Value:

enum {__VA_ARGS__}; \
static const ccuty::stringset _stringset_ ## __LINE__(#__VA_ARGS__); \
switch(_stringset_ ## __LINE__[str])

Allows comparing strings in switch statements.

Example:

int getRGB(const std::string& color) {
  STRING_SWITCH(color, red, blue, green) {
    case red: return 0xf00;
    case blue: return 0x0f0;
    case green: return 0x00f;
    default: return 0;
  }
}

This macro relies on ccuty::stringset.
