Detailed Description

Smart pointer types.

Namespace zypp provides 3 smart pointer types using the boost smart pointer library.

• scoped_ptr Simple sole ownership of single objects. Noncopyable.

• shared_ptr Object ownership shared among multiple pointers

• weak_ptr Non-owning observers of an object owned by shared_ptr.

And zypp::RW_pointer, as wrapper around a smart pointer, poviding const correct read/write access to the object it refers.

Function Documentation

template<class _D> std::ostream& zypp::operator<< (  std::ostream &  str, const shared_ptr< _D > &  obj )  [inline]

Definition at line 65 of file PtrTypes.h.

template<class _D> std::ostream& zypp::operator<< (  std::ostream &  str, const intrusive_ptr< _D > &  obj )  [inline]

Definition at line 74 of file PtrTypes.h.

template<class _D, class _Traits = rw_pointer::Shared<_D>> std::ostream & operator<< (  std::ostream &  str, const RW_pointer< _D, _Ptr > &  obj )  [related, inherited]

Stream output. Print the _D object the RW_pointer refers, or "NULL" if the pointer is NULL. Definition at line 245 of file PtrTypes.h.

template<class _D, class _Traits = rw_pointer::Shared<_D>> _D * rwcowClone (  const _D *  rhs  )  [related, inherited]

Clone the underlying object. Calls rhs ->clone(). Being defined as a function outside RWCOW_pointer allows to overload it, in case a specific _D does not have clone(). Definition at line 347 of file PtrTypes.h.

template<class _D, class _Traits = rw_pointer::Shared<_D>> std::ostream & operator<< (  std::ostream &  str, const RWCOW_pointer< _D, _Ptr > &  obj )  [related, inherited]

Stream output. Print the _D object the RWCOW_pointer refers, or "NULL" if the pointer is NULL. Definition at line 359 of file PtrTypes.h.
