PositioningMode

If a data object is to be re-sorted in a level, then the user can indicate this mode so as to tell the system whether the data object to be sorted is to be sorted in front of or after the reference data object.

A reference data object is a data object which is in the same level as the data object to be sorted. Since the data objects are technically in a list, the user does not indicate the index of the new position, but gives a data object as a reference according to which the current data object is to be sorted.

Values

Before

The current data object is to be sorted before the reference data object.

After

The current data object is to be sorted after the reference data object.
