Detailed Description

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

A naive implementation of roughly a subset of the std::tr1:shared_ptr spec.

Really just roughly - it ignores memory exceptions, for example; also note I didn't read the spec.

The standard template would naturally be preferable, _if_ it was included in the standard libraries of all supported compilers - but as of 2009, that's still a problem...

Constructor & Destructor Documentation

template<typename T>

bdm::shared_ptr< T >::shared_ptr

(

T *

p

)

[inline]

Constructs a shared_ptr that owns the pointer p (unless p is NULL, in which case this constructor creates an empty shared_ptr). When p isn't null, it must have been alllocated by new!

template<typename T>

bdm::shared_ptr< T >::shared_ptr

(

const shared_ptr< T > &

other

)

[inline]

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

template<typename T>

template<typename U >

bdm::shared_ptr< T >::shared_ptr

(

const shared_ptr< U > &

other

)

[inline]

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

Member Function Documentation

template<typename T>

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

(

)

const [inline]

Returns the stored pointer (which remains owned by this instance).

template<typename T>

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

(

)

[inline]

Returns the stored pointer (which remains owned by this instance).

Referenced by bdm::mepdf::from_setting(), and bdm::mepdf::mepdf().

template<typename T>

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

(

)

const [inline]

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.

template<typename T>

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

(

)

[inline]

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.

template<typename T>

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

(

)

const [inline]

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

template<typename T>

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

(

)

[inline]

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