Size
Type Size
The Size class is a very important class in Cello because it gives the size in bytes you can expect an object of a given type to be. This is used by many methods to allocate, assign, or compare various objects.
By default this size is automatically found and recorded by the Cello macro, but if the type does it's own allocation, or the size cannot be found naturally then it may be necessary to override this method.
