Class LongColModuloLongColumnChecked

java.lang.Object

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

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

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

All Implemented Interfaces:

Serializable

public class LongColModuloLongColumnChecked
extends LongColModuloLongColumn

This vector expression implements a Checked variant of LongColModuloLongColumn If the outputTypeInfo is not long it casts the result column vector values to the set outputType so as to have similar result when compared to non-vectorized UDF execution.

Method Detail

evaluate

public void evaluate(org.apache.hadoop.hive.ql.exec.vector.VectorizedRowBatch batch)
              throws HiveException

Description copied from class: VectorExpression

This is the primary method to implement expression logic.

Overrides:

evaluate in class LongColModuloLongColumn

Throws:

HiveException

supportsCheckedExecution

public boolean supportsCheckedExecution()

Description copied from class: VectorExpression

A vector expression which implements a checked execution to account for overflow handling should override this method and return true. In such a case Vectorizer will use Checked variation of the vector expression to process data

Overrides:

supportsCheckedExecution in class VectorExpression

Returns:

true if vector expression implements a Checked variation of vector expression
