Class FilterDoubleColGreaterEqualDoubleColumn

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

All Implemented Interfaces:

Serializable

public class FilterDoubleColGreaterEqualDoubleColumn
extends VectorExpression

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