Detailed Description

template<class T>
class ol::data_ptr< T >

Copyable data smart pointer.

When data_ptr is copied, it makes a copy of hold object. So it behaves similarly std::shared_ptr, but instead of pointing to the same data a copy of data occurs. data_ptr can be used for storing class' private data which on class copy should also be copied. operator= of data_ptr and copy constructor of data_ptr are calling copy constructor of encapsulated type.

Constructor & Destructor Documentation

template<class T>

ol::data_ptr< T >::data_ptr ( T *  ptr = nullptr, Deleter  d = &OpenLibrary_CopyPtr::deleter, Copier  c = &OpenLibrary_CopyPtr::copier  )

inline

Constructor.

Constructs data_ptr object and stores pointer to object of type T inside. data_ptr takes ownership over passed pointer.

• d object deleter. A function which takes pointer to T as parameter. Responsibility of deleter is to delete owned pointer when data_ptr is destroyed.
• c object copier. A function of type data_ptr::Copier. It is called on data_ptr copy. Its responsibility is to create new instance of T and initialize it with data from copied data_ptr.

template<class T>

ol::data_ptr< T >::data_ptr ( const data_ptr< T > &  other )

inline

Copy constructor.

Makes copy of data_ptr. Object kept in data_ptr will be copied too.

template<class T>

ol::data_ptr< T >::data_ptr ( data_ptr< T > &&  other )

inline

Move constructor.

Moves data from one data_ptr to another. No copies are made. Source data_ptr becomes empty.
