Class FilterDoubleColumnInList
java.lang.Object
org.apache.hadoop.hive.ql.exec.vector.expressions.VectorExpression
org.apache.hadoop.hive.ql.exec.vector.expressions.FilterDoubleColumnInList
- All Implemented Interfaces:
- Serializable, IDoubleInExpr
public class FilterDoubleColumnInList
- extends VectorExpression
- implements IDoubleInExpr
Evaluate IN filter on a batch for a vector of doubles.
- See Also:
- Serialized Form
FilterDoubleColumnInList
public FilterDoubleColumnInList()
FilterDoubleColumnInList
public FilterDoubleColumnInList(int colNum)
- After construction you must call setInListValues() to add the values to the IN set.
