Turning the key on starts two behaviors, Driving and Braking. These behaviors execute until the key is turned off, using streaming parameters to communicate with other behaviors.

MagicDraw/Cameo: If the underlying Parameter of an InputPin or OutputPin on a CallBehaviorAction or CallOperationAction is set to streaming, the indicator {stream} optionally displays on the Pin

SysML-1.6: Each «continuous» Parameter (of each corresponding ActivityParameterNode) in Figure D.36 and Figure D.38 should be set to be streaming, because the Continuous Stereotype has a Generalization to Rate

Streaming is a characteristic of UML behavior parameters that supports the input and output of items while a behavior is executing, rather than only when the behavior starts and stops. The flow may be continuous or discrete ...

Rate ... When the stereotype is applied to a parameter, the parameter shall be streaming, and the stereotype gives the number of objects or values that flow in or out of the parameter per time interval while the behavior or operation is executing.

One or more result values may be posted to a streaming output Parameter any time after the invocation of a Behavior up to or at its completion. These result values are then available to affect the further course of the execution of the invoking Behavior..

Unified Modeling Language 2.5.1

If an output Parameter is streaming, then a Behavior execution may provide result values for the Parameter during its course rather than just at completion.

One or more argument values may be posted to a streaming input Parameter at or any time after the invocation of a Behavior and before its completion. These argument values are then available to affect the further course of the Behavior execution ...

If an input Parameter is streaming, then argument values may be provided for the Parameter during the course of a Behavior execution rather than just at invocation.

Parameters may also be marked as streaming (i.e., have the isStreaming property be true). Such Parameters allow values to be passed into and out of a Behavior execution any time during its course, rather than just on invocation and completion.

Continuous ... It is independent from UML streaming, see clause 11.3.2.8. A streaming parameter may or may not apply to continuous flow, and a continuous flow may or may not apply to streaming parameters.
