Class FilterDoubleScalarEqualDoubleColumn

java.lang.Object
  org.apache.hadoop.hive.ql.exec.vector.expressions.VectorExpression
      org.apache.hadoop.hive.ql.exec.vector.expressions.gen.FilterDoubleScalarEqualDoubleColumn

All Implemented Interfaces:

Serializable

public class FilterDoubleScalarEqualDoubleColumn
extends VectorExpression

Generated from template FilterScalarCompareColumn.txt, which covers binary comparison expressions between a scalar and a column, however output is not produced in a separate column. The selected vector of the input VectorizedRowBatch is updated for in-place filtering.
