Detailed Description

Manages temporary file paths during an IOFactory write operation, ensuring safe writes by writing to temporary files first and then moving them to the final destination.

When constructed, the locker replaces the file paths in the FactoryParameters with temporary paths. On writeToActual(), the temporary files are moved to their intended locations. The destructor cleans up any remaining temporary files if writeToActual() was not called.
