public interface WinAggResetContext extends AggResetContext, WinAggFrameContext
AggImplementor.implementReset(AggContext, AggResetContext)
.
The AggResetContext
provides access to the accumulator variables
that should be reset.
Note: the very first reset of windowed aggregates is performed with null knowledge of indices and row count in the partition. In other words, the implementation should treat indices and partition row count as a hint to pre-size the collections.
