xtd::box_integer< type_t > Class Template Reference

#include <box_integer.h>

Definition

template<typename type_t>
class xtd::box_integer< type_t >

Represents a boxed integer object.

class box_integer : public xtd::box<type_t>

Inheritance

xtd::object → xtd::box <type_t> → xtd::box_integer <type_t> ///

Namespace

xtd

Library

xtd.core

Remarks

You can use xtd::box to represent a class or structure that does not inherit from xtd::object. Typically used for integral types.

Use xtd::boxing to box an object.

Use xtd::unboxing to unbox an object.

Examples

The following example shows how to create and use xtd::box_integer<int32>.

auto stringer = [](const object& value) {return value.to_string();};
int32 unboxed_object = 42;
box_integer<int32> boxed_object = unboxed_object;
auto result = stringer(boxed_object);
console::write_line("result = {}", result); // Display: result = 42;
