Definition

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

Represents a boxed integer object.

class box_integer : public xtd::box<type_t>
Represents a boxed integer object.
Definition box_integer.h:52
Represents a boxed object.

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.
For more information about types, see Native types, boxing and unboxing.
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;
const type_t & value() const noexcept
Gets the underlying value.
Definition box.h:85
static void write_line()
Writes the current line terminator to the standard output stream using the specified format informati...
int32_t int32
Represents a 32-bit signed integer.
