Detailed Description

Class RefPtr is an internal pointer class which implements the reference counter.

The class RefPtr contains the real object pointer. Each smart pointer references a RefPtr.

You will never need to work with this class directly.

Constructor & Destructor Documentation

crp::RefPtr::RefPtr	(	void *	object,
		int	rc
	)		`[inline]`

Creates a new reference pointer.

Parameters:

object	Void pointer to the object
rc	Initial number of references
mode	Destruction mode of the pointer

crp::RefPtr::RefPtr	(	void *	object,
		int	rc,
		const DPtr &	source,
		PointerMode	mode = `SOURCE`
	)		`[inline]`

Creates a new reference pointer with source information.

Parameters:

object	Void pointer to the object
rc	Initial number of references
source	Source object pointer
mode	Destruction mode of the pointer

crp::RefPtr::~RefPtr ( ) [inline]

Destroys the instance.

Member Function Documentation

void crp::RefPtr::invalidate ( ) [inline]

Invalidates the reference without destroying the contents of the pointer.

bool crp::RefPtr::is_valid ( ) const [inline]

Returns true if the reference is valid.

A valid reference is a reference, which points to a valid object. Additionally, if the pointer mode of the reference is SOURCE the source pointer must be not zero.

void crp::RefPtr::operator= ( const RefPtr & reference ) [inline]

Copy operator.

Parameters:

reference Other reference

long crp::RefPtr::synchronize_time_stamp ( ) [inline]

Returns the current global time stamp and adds one to the it.
