virtual ~Object ()
 Destroys object. Frees all internal data structures. More...
 
 Object (Object const &x)
 Copy constructor. Doesn't copy anything, really, just initializes new object and enables copy constructing subclasses. More...
 
Objectoperator= (Object const &x)
 Assignment operator. Doesn't copy anything, really, just initializes new object and enables copy constructing subclasses. More...
 
ObjectSharedRefAdded ()
 Increments shared reference count. Shouldn't be called directly; instead, use smart pointers or ThisProtector. More...
 
int SharedRefRemovedSafe ()
 Decrements and returns shared reference count. Shouldn't be called directly; instead, use smart pointers or ThisProtector. More...
 
void SharedRefRemoved ()
 Decrements shared reference count and deletes object if it hits zero. Shouldn't be called directly; instead, use smart pointers or ThisProtector. More...

 Gets reference counter data structure associated with the object. More...
 
int SharedCount () const
 Gets current value of shared refernce counter. More...
 
void FreeOrDetectCycles (int count)
 Reacts on shared reference counter decrement. Shouldn't be called directly, use smart pointers instead. If neccessary, deletes the object. If allowed, initiates loop references lookup. More...
 
void Lock ()
 Implements C# lock() statement locking. Call directly or use LockContext sentry object. More...

virtual bool Is (const TypeInfo &targetType) const
 Check if object represents an instance of type described by targetType. Analog of C# 'is' operator. TypeInfo structure descibing the type to test current object against. More...
 
void __FreePointers ()
 Resets all smart pointers stored inside this object directly (in fields) or indirectly (in value type fields). Used by memory management systems, shouldn't be called directly. More...
 
virtual void SetTemplateWeakPtr (unsigned int argument)
 Set n'th template argument a weak pointer (rather than shared). Allows switching pointers in containers to weak mode. More...
