Class VectorUDFDateLong

java.lang.Object

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

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

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

All Implemented Interfaces:

Serializable

public class VectorUDFDateLong
extends CastLongToDate

Vectorized version of TO_DATE(TIMESTAMP)/TO_DATE(DATE). As TO_DATE() now returns DATE type, this should be the same behavior as the DATE cast operator.
