Class HyperReaderBuilder.HyperVectorAccessor

java.lang.Object

org.apache.drill.exec.vector.accessor.reader.VectorAccessors.BaseHyperVectorAccessor

org.apache.drill.exec.physical.resultSet.model.hyper.HyperReaderBuilder.HyperVectorAccessor

All Implemented Interfaces:

VectorAccessor

Enclosing class:

HyperReaderBuilder

public static class HyperReaderBuilder.HyperVectorAccessor
extends VectorAccessors.BaseHyperVectorAccessor

Vector accessor used by the column accessors to obtain the vector for each column value. That is, position 0 might be batch 4, index 3, while position 1 might be batch 1, index 7, and so on.

Must be here: the reader layer is in the vector package and does not have visibility to java-exec classes.
