Detailed Description

Smart pointer types.

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

Stream output.

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

template<class _D , class _Ptr >

std::ostream & operator<<	(	std::ostream &	str,

	)

related

Stream output.

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

_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().
