Detailed Description
template<class T>
class csRef< T >
A smart pointer.
Maintains and correctly manages a reference to a reference-counted object. This template requires only that the object type T implement the methods IncRef() and DecRef(). No other requirements are placed upon T.

Constructor & Destructor Documentation
|
Construct an invalid smart pointer (that is, one pointing at nothing). Dereferencing or attempting to use the invalid pointer will result in a run-time error, however it is safe to invoke IsValid(). |
|
Construct a smart pointer from a csPtr. Doesn't call IncRef() on the object since it is assumed that the object in csPtr is already IncRef()'ed. |
|
Construct a smart pointer from a raw object reference. Calls IncRef() on the object. |
|
Smart pointer copy constructor.
|
|
Smart pointer destructor. Invokes DecRef() upon the underlying object. |
Member Function Documentation
|
Assign an object reference created with the new operator to this smart pointer.
|
|
Smart pointer validity check. Returns true if smart pointer is pointing at an actual object, otherwise returns false. |
|
Dereference underlying object.
|
|
Cast smart pointer to a pointer to the underlying object.
|
|
Dereference underlying object.
|
|
Assign another object to this smart pointer.
|

Assign a raw object reference to this smart pointer.
|
|
Assign a csPtr to a smart pointer. Doesn't call IncRef() on the object since it is assumed that the object in csPtr is already IncRef()'ed.
