Full quote For structured Actions (StructuredActivityNodes, see sub clause 16.11), data can remain on InputPins during Action execution, otherwise they are immediately removed from the InputPins by the ActionExecution. Next snippet If the Action is an invocation of a Behavior with streaming Parameters ... the Action execution may consume additional data supplied to InputPins corresponding to streaming input Parameters ... Otherwise ... any additional data on InputPins has no effect Related snippets The time at which an Action executes and what inputs are accepted by each execution are determined by the kind of Action it is, characteristics of its InputPins, and the Behavior in which it is used. An Action continues executing until it has completed. The detailed semantics of the execution of an Action and the definition of its completion depend on the particular kind of Action being executed. When completed, an Action execution provides any output data on the OutputPins of the Action, and it terminates. However, if the Action is an invocation of a Behavior with streaming Parameters ... then the Action execution may also post data to OutputPins corresponding to streaming output Parameters before completion of the execution ... The Action execution consumes input data on all InputPins on the Action up to the upper multiplicity for each InputPin.
