enum_ut_

#define enum_ut_	(		namespace_name,
			enum_t,
			underlying_t,
			...
	)

#include <xtd.core/include/xtd/enum.h>

Provides the registration struct for enum with specified underlying type.

Header

#include <xtd/enum>

Library

xtd.core

Parameters

namespace_name	The name of the the namespace. Empty if no namespace.
enum_type	The name of the enum.
underlying_type	The underying type.
...	The enumeration list.

Remarks

This helper is created to facilitate to set the xtd::enum_register with the enumeration identifiers.

Warning

The helper has one limitiation :

• The enumeration's cannot be in a class or struct. The enum must be in the global namespace or in a namespace hierarchy. If the enumeration is in a class or struct, add operators manually and use xtd::enum_register to register the enumeration identifiers.

Examples

The following code show how to use enum_ut_ helper.

#include <xtd/as>
#include <xtd/console>
#include <xtd/enum>
 
using namespace xtd;
 
enum_ut_(, enum_test, byte,
  value_one,
  value_two,
  value_three,
  value_four
);
 
auto main() -> int {
  console::write_line("name = {}", enum_test::value_four);
  console::write_line("value = {}", enum_object(enum_test::value_four).to_byte());
  console::write_line("as<byte> = {}", as<byte>(enum_test::value_four));
  console::write_line("values = {}", enum_object<>::get_values_as_int32<enum_test>());
  console::write_line("names = {}", enum_object<>::get_names<enum_test>());
  console::write_line("entries = {}", enum_object<>::get_entries_as_int32<enum_test>());
}
 
// This code produces the following output :
//
// name = value_four
// value = 3
// as<byte> = 3
// values = [0, 1, 2, 3]
// names = [value_one, value_two, value_three, value_four]
// entries = [(0, value_one), (1, value_two), (2, value_three), (3, value_four)]
