Detailed Description

template<typename _Tp> class std::tr1::shared_ptr< _Tp >

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.

Constructor & Destructor Documentation

shared_ptr () [inline]

Construct an empty shared_ptr.

Postcondition:

use_count()==0 && get()==0

Definition at line 496 of file boost_shared_ptr.h.

shared_ptr (_Tp1 * __p) [inline, explicit]

Construct a shared_ptr that owns the pointer p.

Parameters:

p A pointer that is convertible to element_type*.

Postcondition:

use_count() == 1 && get() == p

Exceptions:

std::bad_alloc,in which case delete p is called.

Definition at line 506 of file boost_shared_ptr.h.

shared_ptr (_Tp1 * __p, _Deleter __d) [inline]

Construct a shared_ptr that owns the pointer p and the deleter d.

Parameters:

p A pointer.
d A deleter.

Postcondition:

use_count() == 1 && get() == p

Exceptions:

std::bad_alloc,in which case d(p) is called.

Definition at line 528 of file boost_shared_ptr.h.

shared_ptr (const shared_ptr< _Tp1 > & __r) [inline]

If r is empty, constructs an empty shared_ptr; otherwise construct a shared_ptr that shares ownership with r.

Parameters:

r A shared_ptr.

Postcondition:

get() == r.get() && use_count() == r.use_count()

Exceptions:

std::bad_alloc,in which case

Definition at line 546 of file boost_shared_ptr.h.

shared_ptr (const weak_ptr< _Tp1 > & __r) [inline, explicit]

Constructs a shared_ptr that shares ownership with r and stores a copy of the pointer stored in r.

Parameters:

r A weak_ptr.

Postcondition:

use_count() == r.use_count()

Exceptions:

bad_weak_ptr when r.expired(), in which case the constructor has no effect.

Definition at line 560 of file boost_shared_ptr.h.

shared_ptr (std::auto_ptr< _Tp1 > & __r) [inline, explicit]

Postcondition:

use_count() == 1 and r.get() == 0

Definition at line 573 of file boost_shared_ptr.h.
