C++ named requirements: PODType

From cppreference.com

C++ named requirements
 

Specifies that the type is POD (Plain Old Data) type. This means the type is compatible with the types used in the C programming language, that is, can be exchanged with C libraries directly, in its binary form.

Note: the standard doesn't define a named requirement with this name. This is a type category defined by the core language. It is included here as a named requirement only for consistency.

This type requirement is deprecated in the C++ standard. All of its uses have been replaced by the more refined type requirements, such as TrivialType

(since C++20)

[edit] Requirements

Either:

  • a scalar type;
  • a class type (class or struct or union) that:
  • is an aggregate type;
  • has no non-static members that are non-POD;
  • has no members of reference type;
  • has no user-defined copy constructor;
  • has no user-defined destructor;
(until C++11)
(since C++11)
  • an array of such type.
