Class ScheduleType

java.lang.Object

org.oddjob.schedules.ScheduleType

All Implemented Interfaces:

ArooaValue, ArooaLifeAware

public class ScheduleType
extends Object
implements ArooaValue, ArooaLifeAware

Description

Applies a schedule to a given date to provide a calculated date. If the date is not provide the current date is used. This type will most often be used to calculate the current date or the current time, or a next business date.

The ScheduleResult is also available and this can be used to calculate recurring schedules as in the example below.

Example

Display the time now. Note the date variable is passed into Oddjob during the testing of this example so the time can be fixed, but run as is it will be null and so the current time will be displayed.

<oddjob id="this">
    <job>
        <sequential>
            <jobs>
                <variables id="time">
                    <now>
                        <schedule>
                            <date>
                                <value value="${date}"/>
                            </date>
                            <schedule>
                                <schedules:now xmlns:schedules="http://rgordon.co.uk/oddjob/schedules"/>
                            </schedule>
                        </schedule>
                    </now>
                    <formatted>
                        <format date="${time.now}" format="hh:mm a"/>
                    </formatted>
                </variables>
                <echo id="echo-time">The time now is ${time.formatted}</echo>
            </jobs>
        </sequential>
    </job>
</oddjob>

Example

Use a schedule with a time zone. This example displays when tomorrow starts in Hong Kong in the local time.

<oddjob id="this">
    <job>
        <sequential>
            <jobs>
                <variables id="time">
                    <now>
                        <schedule timeZone="Asia/Hong_Kong">
                            <date>
                                <value value="${date}"/>
                            </date>
                            <schedule>
                                <schedules:day-after xmlns:schedules="http://rgordon.co.uk/oddjob/schedules"/>
                            </schedule>
                        </schedule>
                    </now>
                    <formatted>
                        <format date="${time.now}" format="hh:mm a"/>
                    </formatted>
                </variables>
                <echo id="echo-time">Tomorrow in Hong Kong starts at ${time.formatted} our time.</echo>
            </jobs>
        </sequential>
    </job>
</oddjob>

Note that to display the current time in Hong Kong we would use a Time Zone on the format type, not on the now schedule because dates internally use UTC (Coordinated Universal Time) so now will always be the same regardless of time zone.

Example

Calculate the next business date. Two schedule types are used, the first calculates the next day, the next takes this and applies it to a schedule that defines the business days. The result will be the next business day.

            <jobs>

                        <schedule>
                            <date>
                                <value value="${date}"/>
                            </date>
