Detailed Description

template<typename T>
class OFshared_ptr< T >::Data

Helper class containing the reference to the managed object and the reference counter.

Constructor & Destructor Documentation

Data()

template<typename T>

OFshared_ptr< T >::Data::Data ( T *const  pt )

inline

Construct reference and counter from a raw pointer.

Parameters

pt	the raw pointer that becomes the managed object.

~Data()

template<typename T>

OFshared_ptr< T >::Data::~Data ( )

inline

Delete the managed object.

We are deleted only if the reference counter reached zero, so we now have to delete the managed object.

References OFshared_ptr< T >::Data::m_pT.

Member Function Documentation

decrement_count()

template<typename T>

OFBool OFshared_ptr< T >::Data::decrement_count ( )

inline

Decrement the reference counter in a thread-safe and (if possible) lock-free fashion.

Returns

OFTrue if the reference counter reached zero, OFFalse otherwise.

References OFMutex::lock(), OFshared_ptr< T >::Data::m_Count, OFshared_ptr< T >::Data::m_Mutex, and OFMutex::unlock().

Referenced by OFshared_ptr< DcmItem >::destroy().

pointer()

template<typename T>

T* OFshared_ptr< T >::Data::pointer ( ) const

inline

Get the managed object.

Returns

a pointer to the managed object.
