It contains a list of nodes that shall be executed sequentially. There are different kinds of nodes: simple nodes representing single commands to be carried out (Action, Return, Continue, Break,Throwand TerminateLanes) and compound nodes that may themselves embed flows (Group, Loop, Branch, Parallel, MutexGroupand Handler). OTX flows are comparable to the block concept as used by other programming languages. |
