ObjectAggregationMap

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.

  7. def destructiveIterator(): Iterator[AggregationBufferEntry]

    Returns a destructive iterator of AggregationBufferEntry.

    Returns a destructive iterator of AggregationBufferEntry. Notice: it is illegal to call any method after destructiveIterator() has been called.

  8. def dumpToExternalSorter(groupingAttributes: Seq[Attribute], aggregateFunctions: Seq[AggregateFunction]): UnsafeKVExternalSorter

    Dumps all entries into a newly created external sorter, clears the hash map, and returns the external sorter.
