std::experimental::shared_ptr is a modified version ofstd::shared_ptr that adds support for arrays.

constructs newshared_ptr(public member function)[edit] | |
Observers | |
| returns the stored pointer (public member function)[edit] | |
| dereferences the stored pointer (public member function)[edit] | |

| hash support forstd::experimental::shared_ptr (class template specialization)[edit] |
The following member functions work withstd::experimental::shared_ptr instead ofstd::shared_ptr andstd::experimental::weak_ptr instead ofstd::weak_ptr. The behavior is otherwise identical.
destructs the owned object if no moreshared_ptrs link to it(public member function of std::shared_ptr<T>)[edit] | |
assigns theshared_ptr(public member function of std::shared_ptr<T>)[edit] | |
Modifiers | |
| replaces the managed object (public member function of std::shared_ptr<T>)[edit] | |
| swaps the managed objects (public member function of std::shared_ptr<T>)[edit] | |
Observers | |
returns the number ofshared_ptr objects referring to the same managed object(public member function of std::shared_ptr<T>)[edit] | |
(until C++20) | checks whether the managed object is managed only by the currentshared_ptr object(public member function of std::shared_ptr<T>)[edit] |
| checks if the stored pointer is not null (public member function of std::shared_ptr<T>)[edit] | |
| provides owner-based ordering of shared pointers (public member function of std::shared_ptr<T>)[edit] | |
These non-member functions are declared in thestd::experimental namespace, and work withstd::experimental::shared_ptr rather thanstd::shared_ptr, but otherwise behaves identically to the corresponding C++14 function.
| creates a shared pointer that manages a new object (function template)[edit] | |
| creates a shared pointer that manages a new object allocated using an allocator (function template)[edit] | |
| returns the deleter of specified type, if owned (function template)[edit] | |
(removed in C++20)(removed in C++20)(removed in C++20)(removed in C++20)(removed in C++20)(C++20) | compares with anothershared_ptr or withnullptr(function template)[edit] |
| outputs the value of the stored pointer to an output stream (function template)[edit] | |
(C++11) | specializes thestd::swap algorithm (function template)[edit] |
specializes atomic operations forstd::shared_ptr(function template)[edit] |
These class templates are declared in thestd::experimental namespace, and work withstd::experimental::shared_ptr andstd::experimental::weak_ptr rather thanstd::shared_ptr andstd::weak_ptr, but otherwise behaves identically to the corresponding C++14 class template.
(C++11) | provides mixed-type owner-based ordering of shared and weak pointers (class template)[edit] |
(C++11) | allows an object to create ashared_ptr referring to itself(class template)[edit] |
