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, class _Ptr>

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.

template<class _D, class _Ptr>

bool operator==	(	const RW_pointer< _D, _Ptr > &	lhs,

	)			[related, inherited]

Definition at line 333 of file PtrTypes.h.

template<class _D, class _Ptr>

bool operator!=	(	const RW_pointer< _D, _Ptr > &	lhs,
		const RW_pointer< _D, _Ptr > &	rhs
	)			[related, inherited]

Definition at line 341 of file PtrTypes.h.

template<class _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().

std::ostream & operator<<	(	std::ostream &	str,
		const RWCOW_pointer< _D, _Ptr > &	obj

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