get_type()

virtual type_object xtd::object::get_type ( ) const

virtualnoexcept

Gets the type of the current instance.

Returns

The type instance that represents the exact runtime type of the current instance.

Examples

The following code example demonstrates that xtd::object::get_type returns the runtime type of the current instance.

#include <xtd/as>
#include <xtd/console>
 
using namespace xtd;
 
class my_base_class : public object {
};
 
class my_derived_class: public my_base_class {
};
 
auto main() -> int {
  auto my_base = my_base_class {};
  auto my_derived = my_derived_class {};
  object& o = as<object>(my_derived);
  my_base_class& b = as<my_base_class>(my_derived);
  
  console::write_line("my_base: type is {}", my_base.get_type());
  console::write_line("my_derived: type is {}", my_derived.get_type());
  console::write_line("object o = my_derived: type is {}", o.get_type());
  console::write_line("my_base_class b = my_derived: type is {}", b.get_type());
  
  console::write_line();
  console::write_line("my_base: type is {}", typeof_(my_base));
  console::write_line("my_derived: type is {}", typeof_(my_derived));
  console::write_line("object o = my_derived: type is {}", typeof_(o));
  console::write_line("my_base_class b = my_derived: type is {}", typeof_(b));
}
 
// This code produces the following output :
//
// my_base: type is my_base_class
// my_derived: type is my_derived_class
// object o = my_derived: type is my_derived_class
// my_base_class b = my_derived: type is my_derived_class
//
// my_base: type is my_base_class
// my_derived: type is my_derived_class
// object o = my_derived: type is my_derived_class
// my_base_class b = my_derived: type is my_derived_class
