abstract class AggregationIterator extends Iterator[UnsafeRow] with Logging

The base class of SortBasedAggregationIterator, TungstenAggregationIterator and ObjectAggregationIterator. It mainly contains two parts: 1. It initializes aggregate functions. 2. It creates two functions, processRow and generateOutput based on AggregateMode of its aggregate functions. processRow is the function to handle an input. generateOutput is used to generate result.
