Class DateType

java.lang.Object

cascading.tuple.type.DateType

All Implemented Interfaces:

CoercibleType<java.lang.Long>, java.io.Serializable, java.lang.reflect.Type

public class DateType
extends java.lang.Object
implements CoercibleType<java.lang.Long>

Class DateCoercibleType is an implementation of CoercibleType.

Given a dateFormatString, using the SimpleDateFormat format, this CoercibleType will convert a value from the formatted string to a Long canonical type and back.

This class when presented with a Long timestamp value will assume the value is in UTC.

See DateParser and DateFormatter for similar Operations for use within a pipe assembly.
