org.apache.drill.exec.physical.rowSet.IndirectRowIndex

All Implemented Interfaces:

ColumnReaderIndex

public class IndirectRowIndex
extends ReaderIndex

Reader index that points to each row indirectly through the selection vector. The offset() method points to the actual data row, while the ReaderIndex.logicalIndex() method gives the position relative to the indirection vector. That is, the position increases monotonically, but the index jumps around as specified by the indirection vector.
