reference_equals()

template<typename object_a_t , typename object_b_t >

static bool xtd::object::reference_equals ( const object_a_t &  object_a, const object_b_t &  object_b  )

inlinestaticnoexcept

Determines whether the specified object instances are the same instance.

Parameters

object_a	The first object to compare.
object_b	The second object to compare.

Returns

true if object_a is the same instance as object_b or if both are null references; otherwise, false.

Examples

The following code example uses xtd::object::reference_equals to determine if two objects are the same instance.

#include <xtd/console>
 
using namespace xtd;
 
auto main() -> int {
  object* o = nullptr;
  object* p = null;
  object* q = new object;
  
  console::write_line(object::reference_equals(*o, *p));
  p = q;
  console::write_line(object::reference_equals(*p, *q));
  console::write_line(object::reference_equals(*o, *p));
  
  delete q;
}
 
// This code produces the following output :
//
// true
// true
// false
