java.lang.Object

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

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

org.apache.hadoop.hive.ql.exec.vector.expressions.IfExprDecimal64ColumnDecimal64Column

All Implemented Interfaces:

Serializable

public class IfExprDecimal64ColumnDecimal64Column
extends IfExprLongColumnLongColumn

Compute IF(expr1, expr2, expr3) for 3 input column expressions. The first is always a boolean (LongColumnVector). The second and third are long columns or long expression results.

Method Detail

getDescriptor

public VectorExpressionDescriptor.Descriptor getDescriptor()

Overrides:

getDescriptor in class IfExprLongColumnLongColumn

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:
