Detailed Description

Strongly typed wrapper for bounded open rolling windows.

Parameters

delta The scalar delta from the current row. Must be valid, behaviour is undefined if not. If the scalar represents a floating point type the value must be neither inf nor nan, otherwise behaviour is undefined.

The endpoints of this window are excluded.
