Detailed Description

template<typename T>
class bdm::object_ptr< T >

A wrapper of shared_ptr which is never empty.

T must have a default constructor.

Note that shared_ptr's destructor isn't virtual - don't call delete on pointers to instances of this class.

Constructor & Destructor Documentation

template<typename T>

bdm::object_ptr< T >::object_ptr

(

)

[inline]

Default constructor.

Calls T's default constructor.

template<typename T>

bdm::object_ptr< T >::object_ptr

(

const shared_ptr< T > &

b

)

[inline]

Upcast from shared_ptr<T> to object_ptr<T>.

Parameters:

b

The shared pointer, which must not be empty.

References bdm_assert_debug.

template<typename T>

bdm::object_ptr< T >::object_ptr

(

T *

p

)

[inline]

Constructs an object_ptr that owns the pointer p. p must have been alllocated by new!

References bdm_assert_debug.

Member Function Documentation

const T * bdm::shared_ptr< T >::get

(

)

const [inline, inherited]

Returns the stored pointer (which remains owned by this instance). For empty instances, this method returns NULL.

T * bdm::shared_ptr< T >::get

(

)

[inline, inherited]

Returns the stored pointer (which remains owned by this instance). For empty instances, this method returns NULL.

bdm::shared_ptr< T >::operator bool

(

)

const [inline, inherited]

Boolean cast.

This operator returns true if and only if the instance isn't empty.

bdm::shared_ptr< T >::operator shared_ptr< const U >

(

)

const [inline, inherited]

const cast

Shared pointer to T can be converted to shared pointer to const T, just like T * can be converted to T const *.

const T & bdm::shared_ptr< T >::operator*

(

)

const [inline, inherited]

Returns a reference to the object pointed to by the stored pointer. This method may only be called when the stored pointer isn't NULL.

T & bdm::shared_ptr< T >::operator*

(

)

[inline, inherited]

Returns a reference to the object pointed to by the stored pointer. This method may only be called when the stored pointer isn't NULL.

const T * bdm::shared_ptr< T >::operator->

(

)

const [inline, inherited]

Returns the stored pointer (which remains owned by this instance). This method may only be called when the stored pointer isn't NULL.

T * bdm::shared_ptr< T >::operator->

(

)

[inline, inherited]

Dereferences the stored pointer (which remains owned by this instance). This method may only be called when the stored pointer isn't NULL.

long bdm::shared_ptr< T >::use_count

(

)

const [inline, inherited]

Returns the number of shared_ptr instances (including this instance) that share ownership with this instance. For empty instances, this method returns 0.
