Object flows model the movement of object tokens between object nodes and actions. In an Activity Diagram, tokens representing objects travel along object flows from an object node into an action and then onward to subsequent actions or nodes, showing how data or object instances pass through the workflow. This movement is separate from control flows, which carry control tokens that dictate the order of actions. Pins are the input/output points on actions where tokens pass, but they are not the channels of movement themselves—the object flows are. Activity parameters specify the inputs and outputs of the activity as a whole rather than the ongoing movement of tokens through the diagram.
