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.
