4// Summary: The Ort C++ API is a header only wrapper around the Ort C API.
5//
6// The C++ API simplifies usage by returning values directly instead of error codes, throwing exceptions on errors
7// and automatically releasing resources in the destructors. The primary purpose of C++ API is exception safety so
8// all the resources follow RAII and do not leak memory.
9//
10// Each of the C++ wrapper classes holds only a pointer to the C internal object. Treat them like smart pointers.
11// To create an empty object, pass 'nullptr' to the constructor (for example, Env e{nullptr};). However, you can't use them
12// until you assign an instance that actually holds an underlying object.
13//
14// For Ort objects only move assignment between objects is allowed, there are no copy constructors.
15// Some objects have explicit 'Clone' methods for this purpose.
16//
17// ConstXXXX types are copyable since they do not own the underlying C object, so you can pass them to functions as arguments
18// by value or by reference. ConstXXXX types are restricted to const only interfaces.
19//
20// UnownedXXXX are similar to ConstXXXX but also allow non-const interfaces.
21//
22// The lifetime of the corresponding owning object must eclipse the lifetimes of the ConstXXXX/UnownedXXXX types. They exists so you do not
23// have to fallback to C types and the API with the usual pitfalls. In general, do not use C API from your C++ code.
