 * Information for a call to
 * {@link AggImplementor#implementReset(AggContext, AggResetContext)}.
 *
 * The {@link 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.
