Package org.apache.drill.exec.physical.resultSet.impl

Class TupleState.RowState

java.lang.Object

org.apache.drill.exec.physical.resultSet.impl.ContainerState

org.apache.drill.exec.physical.resultSet.impl.TupleState

org.apache.drill.exec.physical.resultSet.impl.TupleState.RowState

All Implemented Interfaces:

AbstractTupleWriter.TupleWriterListener

Enclosing class:

TupleState

public static class TupleState.RowState
extends TupleState

Handles the details of the top-level tuple, the data row itself. Note that by "row" we mean the set of vectors that define the set of rows.
