ReferencedObject is a reference counting base class. it has an integer reference counter so that dynamic objects can have their memory allocation handled by the scim smart pointer: Pointer<>. This keeps the memory management in scim consistent across all classes. If you derive a class from ReferencedObject and allocate it on the heap, you free the memory and destroy the object by calling unref(), not delete.
scim::ReferencedObject::ReferencedObject | ( | ) | [protected] |
Constructor.
virtual scim::ReferencedObject::~ReferencedObject | ( | ) | [protected, pure virtual] |
Destructor.
void scim::ReferencedObject::set_referenced | ( | bool | reference | ) | [protected] |
Set the internal referenced flag.
reference | - true if the initial reference count must be removed by owner. |
bool scim::ReferencedObject::is_referenced | ( | ) | const |
The referenced flag setting.
void scim::ReferencedObject::ref | ( | ) |
Increase an object's reference count by one.
void scim::ReferencedObject::unref | ( | ) |
Decrease an object's reference count by one. When the reference count becomes zero delete is called. Remember, with ReferencedObject you must call unref() on dynmaically allocated objects, not delete.
