class ObjectAggregationMap extends AnyRef

An aggregation map that supports using safe SpecificInternalRows aggregation buffers, so that we can support storing arbitrary Java objects as aggregate function states in the aggregation buffers. This class is only used together with ObjectHashAggregateExec.
