Analysis Office: Is there a method that returns the Dimensions that are moved to Rows or Columns?

Hello, I'm going through the SAP User Guide but I'm not able to find a method that does what I need. I need a method that returns all the dimensions that have been moved to the drill-down either as a row or a column. For example if I have CURRENCY and COUNTRY as free characteristics, and I drag them over to Rows, the method should return CURRENCY and COUNTRY in a list or something. Is there a way to do this?

Thanks
