## 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 Symbol 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().

## ◆ 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`.
