Detailed Description
Handle/Body: Base for refcounted representation classes (Body).
_Body provides the reference counter for representation classes manipulated through _Handle. For details see class _Handle.
The initial reference count is zero. Calling ref(), the reference counter is increased. Calling unref(), the reference counter is decreased. If the reference count becomes zero, the object is deleted.
Any attempt to delete an object with a non zero reference count will throw an exeption.
Any attempt to unref() an object with a zero reference count will throw an exeption.
Stream output operator are provided for _Body and _Body*. Both use dumpOn(), which might be overloaded by derived classes.
Constructor & Destructor Documentation
| _Body::_Body |
( |
|
) |
[inline] |
|
|
|
Constructor. Initial reference count is zero. |
| _Body::_Body |
( |
const _Body & |
rhs |
) |
[inline] |
|
|
|
CopyConstructor. Initial reference count is zero. |
| virtual _Body::~_Body |

[inline, virtual] |
|
|
|
Destructor. Throws exception if reference count is not zero. |
Member Function Documentation
| virtual std::ostream& _Body::dumpOn |
( |
std::ostream & |
str |
) |
const [virtual] |
|
|
|
Derived classes may overload this to realize std::ostream & operator<< for _Body classes. |
| _Body& _Body::operator= |
( |
const _Body & |
rhs |
) |
[inline] |
|
|
|
Assignment. Reference count remains untouched. |
| static void _Body::ref |
( |
const _Body * |
obj_r |
) |
[inline, static] |
|
|
|
Safe increment reference counter. Ignore NULL object pointer passed as argument. |
| void _Body::ref |
( |
|
) |
const [inline] |
|
|
|
Increment reference counter. |
| virtual void _Body::ref_to |
( |
unsigned |
|
) |
const [inline, protected, virtual] |
|
|
|
Trigger derived classes after refCount was increased. |
| unsigned _Body::refCount |
( |
|
) |
const [inline] |
|
|
|
Current reference counter value. |
| static void _Body::unref |
( |
const _Body * |
obj_r |
) |
[inline, static] |
|
|
|
Safe decrement reference counter. Ignore NULL object pointer passed as argument.. |
| void _Body::unref |
( |
|
) |
const [inline] |
|
|
|
Decrement reference counter and delete the object if reference count got zero. Throws exception if reference count already is zero. |
| virtual void _Body::unref_to |
( |
unsigned |
|
) |
const [inline, protected, virtual] |
|
|
|
Trigger derived classes after refCount was decreased. No trigger is sent, if refCount got zero (i.e. the object is deleted). |
