Class FilterDecimal64ColEqualDecimal64Column

java.lang.Object

org.apache.hadoop.hive.ql.exec.vector.expressions.VectorExpression

org.apache.hadoop.hive.ql.exec.vector.expressions.gen.FilterLongColEqualLongColumn

org.apache.hadoop.hive.ql.exec.vector.expressions.gen.FilterDecimal64ColEqualDecimal64Column

All Implemented Interfaces:

Serializable

public class FilterDecimal64ColEqualDecimal64Column
extends FilterLongColEqualLongColumn

Generated from template FilterDecimal64ColumnCompareDecimal64Column.txt, which covers decimal64 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.

Overrides:

shouldConvertDecimal64ToDecimal

public boolean shouldConvertDecimal64ToDecimal()

Description copied from class: VectorExpression

By default vector expressions do not handle decimal64 types and should be converted into Decimal types if its output cannot handle Decimal64. Decimal64 that only deal with Decimal64 types cannot handle conversions so they should override this method and return false.

Overrides:

shouldConvertDecimal64ToDecimal in class VectorExpression
