Gets the position at the specified (zero-based) index, by values of its member data. This is in aid of higher performance for any implementation that does not internally use FdoIDirectPosition objects for storage, or for an application seeking to avoid overhead of accessor methods.
- Parameters:
-
| index | Input Zero-based index in the object's list of positions. |
| x | Output X ordinate value. |
| y | Output Y ordinate value. |
| z | Output Z ordinate value. |
| m | Output M ordinate value. |
| dimensionality | Output Dimensionality of ordinates in this position. |
- Returns:
- Returns nothing
