◆ boolean_object

using xtd::boolean_object = typedef box<bool>

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

Represent a boxed bool.

Header: #include <xtd/boolean_object>

Namespace: xtd

Library: xtd.core

Examples: The following example shows how to create and use xtd::boolean_object.
auto stringer = [](const object& value) {return value.to_string();};
bool unboxed_object = true;
boolean_object boxed_object = unboxed_bool;
auto result = stringer(boxed_object);
console::write_line("result = {}", result); // Display: result = true;

◆ size_object

using xtd::size_object = typedef box_integer<size_t>

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

Represent a boxed size_t.

Namespace: xtd

Library: xtd.core

Examples: The following example shows how to create and use xtd::size_object.
auto stringer = [](const object& value) {return value.to_string();};
size_t unboxed_object = 42;
size_object boxed_object = unboxed_object;
auto result = stringer(boxed_object);
console::write_line("result = {}", result); // Display: result = 42;
