Detailed Description

template<class D, class DTraits = rw_pointer::Shared<D>>
struct zypp::RWCOW_pointer< D, DTraits >

RW_pointer supporting 'copy on write' functionality.

Write access to the underlying object creates a copy, iff the object is shared.

See RW_pointer.

Friends And Related Function Documentation

◆ rwcowClone()

template<class D >
D * rwcowClone ( const D *  rhs)
related

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 443 of file PtrTypes.h.

◆ operator<<()

template<class D , class DPtr >
std::ostream & operator<< ( std::ostream &  str,
const RWCOW_pointer< D, DPtr > &  obj 
)
related

Stream output.

Print the D object the RWCOW_pointer refers, or "NULL" if the pointer is NULL.
