## 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.

References m_Count, m_Mutex, and m_pT.

## ◆ ~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 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 m_Count, and m_Mutex.

## ◆ pointer()

template<typename T>

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

Get the managed object.

Returns
  a pointer to the managed object.

References m_pT.
