Which API function returns the destination info for an expression?

• A. api.data.GetExpressionDestinationInfo
• B. api.data.calculate
• C. api.data.getdatabuffer
• D. api.data.setdatabuffer

Answer: (A)

The main idea is identifying which API call tells you where an expression’s result will be written. api.data.GetExpressionDestinationInfo is the one that retrieves the destination information for an expression, so it directly answers the question by returning where the expression’s output goes (the destination). The other functions perform different tasks: api.data.calculate runs the calculation, while api.data.getdatabuffer and api.data.setdatabuffer deal with reading or writing raw data buffers, not with where expression results are routed. So the function that clearly provides the destination info is api.data.GetExpressionDestinationInfo.
