inline

Set the size of all streaming input terminals connected to the output terminal for a task identified by key.

Template Parameters

<i>	The index of the terminal through which to set the size.

Parameters

key	The key identifying the task (or tasks) for which to set the streaming terminal size.
size	THe size to set (i.e., the number of elements to accumulate).
t	The tasks's output terminals.
