private

A no-op unless at least one of the expressions depends on time and the values have not already been updated in this timestep. Only the time dependent components are re-evaluated, but all three are copied to the device, since they share one transfer anyway.

Parameters

[in]	time	The current time state.
[in,out]	strm	The device stream to issue the copies on.
