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

Member types

Member type Definition
element_type std::remove_extent_t<T>

Member functions

constructs new shared_ptr
(public member function)
Observers
returns the stored pointer
(public member function)
dereferences the stored pointer
(public member function)
provides index access to the array
(public member function)

Non-member functions

applies static_cast, dynamic_cast, const_cast, or reinterpret_cast to the stored pointer
(function template)

Helper classes

hash support for std::experimental::shared_ptr
(class template specialization)


Members and non-members identical to std::shared_ptr

Member functions

The following member functions work with std::experimental::shared_ptr instead of std::shared_ptr and std::experimental::weak_ptr instead of std::weak_ptr. The behavior is otherwise identical.

destructs the owned object if no more shared_ptrs link to it
(public member function of std::shared_ptr)
assigns the shared_ptr
(public member function of std::shared_ptr)
Modifiers
replaces the managed object
(public member function of std::shared_ptr)
swaps the managed objects
(public member function of std::shared_ptr)
Observers
returns the number of shared_ptr objects referring to the same managed object
(public member function of std::shared_ptr)
(until C++20)
checks whether the managed object is managed only by the current shared_ptr instance
(public member function of std::shared_ptr)
checks if the stored pointer is not null
(public member function of std::shared_ptr)
provides owner-based ordering of shared pointers
(public member function of std::shared_ptr)

Non-member functions

These non-member functions are declared in the std::experimental namespace, and work with std::experimental::shared_ptr rather than std::shared_ptr, but otherwise behaves identically to the corresponding C++14 function.

creates a shared pointer that manages a new object
(function template)
creates a shared pointer that manages a new object allocated using an allocator
(function template)
returns the deleter of specified type, if owned
(function template)
compares with another shared_ptr or with nullptr
(function template)
outputs the value of the stored pointer to an output stream
(function template)
specializes the std::swap algorithm
(function template)
specializes atomic operations for std::shared_ptr
(function template)

Helper class templates

These class templates are declared in the std::experimental namespace, and work with std::experimental::shared_ptr and std::experimental::weak_ptr rather than std::shared_ptr and std::weak_ptr, but otherwise behaves identically to the corresponding C++14 class template.

provides mixed-type owner-based ordering of shared and weak pointers
(class template)
allows an object to create a shared_ptr referring to itself
(class template)
