aggregate
public void aggregate(ByteBuffer buf, int position, int startRow, int endRow)
Description copied from interface:VectorAggregator
Aggregate a range of rows into a single aggregation slot. Implementations must not change the position, limit or mark of the given buffer- Specified by:
aggregate
in interfaceVectorAggregator
- Parameters:
buf
- byte buffer storing the byte array representation of the aggregateposition
- offset within the byte buffer at which the current aggregate value is storedstartRow
- first row of the range within the current batch to aggregate (inclusive)endRow
- end row of the range (exclusive)
-
aggregate
public void aggregate(ByteBuffer buf, int numRows, int[] positions, @Nullable int[] rows, int positionOffset)
Description copied from interface:VectorAggregator
Aggregate a list of rows ("rows") into a list of aggregation slots ("positions"). Implementations must not change the position, limit or mark of the given buffer- Specified by:
aggregate
in interfaceVectorAggregator
- Parameters:
buf
- byte buffer storing the byte array representation of the aggregatenumRows
- number of rows to aggregatepositions
- array of aggregate value positions within the buffer; must be at least as long as "numRows"rows
- array of row numbers within the current row batch; must be at least as long as "numRows". If null, the aggregator will aggregate rows from 0 (inclusive) to numRows (exclusive).positionOffset
- an offset to apply to each value from "positions"
