Object oriented SDL is almost the same as 'ordinary' SDL. Your
states, transitions and tasks also remain the same But there'd
be a few changes due to use of OO constructs.
If you were deriving process types, you will also have virtual
transitions (identified by specifying that a input signal being
virtual). This is just one advantage/difference.

Your class would probably map onto a SDL Process Type which can
be instantiated inside a block.

Apart from channels, routes and signals, you will also need to
use "Gates" in SDL.
