Class PeriodObjectModel

java.lang.Object

com.highdeal.chrono.hci.PeriodObjectModel

All Implemented Interfaces:

IPeriodObjectModel, XMLMarshallable

public class PeriodObjectModel
extends Object
implements XMLMarshallable, IPeriodObjectModel

This Java class defines a period object that represents a data object (see XML-marshallable element) valid upon a certain period of time specified by a start timestamp and an end timestamp; This class is necessary to handle a chronology of data elements.

Note

The timestamps can be null, meaning that the object has no defined starting and/or ending.
