A smart pointer with reference-counted copy semantics.
The object pointed to is deleted when the last shared_ptr pointing to it is destroyed or reset.
Definition at line 93 of file bits/shared_ptr.h.
|
inlinenoexcept |
Construct an empty shared_ptr.

inlineexplicit |
Construct a shared_ptr that owns the pointer __p.
__p | A pointer that is convertible to element_type*. |
std::bad_alloc,in | which case delete __p is called. |
Definition at line 116 of file bits/shared_ptr.h.
|
inline |
Construct a shared_ptr that owns the pointer __p and the deleter __d.
__p | A pointer. |
__d | A deleter. |
std::bad_alloc,in | which case __d(__p) is called. |
Requirements: _Deleter's copy constructor and destructor must not throw
__shared_ptr will release __p by calling __d(__p)
Definition at line 133 of file bits/shared_ptr.h.
|
inline |
Construct a shared_ptr that owns a null pointer and the deleter __d.
__p | A null pointer constant. |
__d | A deleter. |
std::bad_alloc,in | which case __d(__p) is called. |
Requirements: _Deleter's copy constructor and destructor must not throw
The last owner will call __d(__p)

inlinenoexcept |
Constructs a shared_ptr instance that stores __p and shares ownership with __r.
__r | A shared_ptr. |
__p | A pointer that will remain valid while *__r is valid. |
This can be used to construct a shared_ptr
to a sub-object of an object managed by an existing shared_ptr
.
Definition at line 210 of file bits/shared_ptr.h.

inlinenoexcept |
If __r is empty, constructs an empty shared_ptr; otherwise construct a shared_ptr that shares ownership with __r.
__r | A shared_ptr. |
Definition at line 221 of file bits/shared_ptr.h.
|
inlinenoexcept |
Move-constructs a shared_ptr instance from __r.
__r | A shared_ptr rvalue. |

Constructs a shared_ptr that shares ownership with __r and stores a copy of the pointer stored in __r.
__r | A weak_ptr. |
bad_weak_ptr | when __r.expired(), in which case the constructor has no effect. |

friend |
Create an object that is owned by a shared_ptr.
__a | An allocator. |
__args | Arguments for the _Tp object's constructor. |
An | exception thrown from _Alloc::allocate or from the constructor of _Tp. |
A copy of __a will be used to allocate memory for the shared_ptr and the new object.
