CFilter is the base class of all primitive
filters. It cannot be instantiated because it is an abstract class. The
clone method is a null method to enforce that
this must be clonable.
A series of handler methods are declared virtual for derived classes to write their own handler implementations. Because all of these handlers provide a default implementation, derived classes need not write an implementation for all of the handlers. All of the handlers in the base class do nothing more than return the ring item passed as an argument.
CFilter();
The default constructor is a no-op.
virtual ~CRingItem();
The virtual destructor is a no-op.
virtual const CRingItem* clone();
This is declared null.
virtual CRingItem* handleRingItem(CRingItem* item);
Returns a copy of this.
virtual CRingItem* handleStateChangeItem(CRingStateChangeItem* item);
Downcasts the item pointer to a CRingItem and returns it.
virtual CRingItem* handleScalerItem(CRingScalerItem* item);
Downcasts the item pointer to a CRingItem and returns it.
virtual CRingItem* handlePhysicsEventItem(CPhysicsEventItem* item);
Downcasts the item pointer to a CRingItem and returns it.
virtual CRingItem* handleFragmentItem(CRingFragmentItem* item);
Downcasts the item pointer to a CRingItem and returns it.
virtual CRingItem* handlePhysicsEventCountItem(CRingPhysicsEventCountItem* item);
Downcasts the item pointer to a CRingItem and returns it.
virtual CRingItem* handleTextItem(CRingTextItem* item);
Downcasts the item pointer to a CRingItem and returns it.
virtual void initialize();
Method executed prior to the first ring item is handled. It is useful for one-time initialization tasks. You should not use it for code that must execute when a begin run occurs.
virtual void finalize();
Method executed after the last ring item is handled. It is useful for clean up tasks such as writing a result to a file. You should not use it for code that must execute when an end run occurs.
