The "REQUEST" method in a "VEVENT" component provides the following scheduling functions:
public class ProcessRequest extends ProcessPublish
<h2>3.2.2. REQUEST</h2> <pre>
The "REQUEST" method in a "VEVENT" component provides the following scheduling functions:
o Invite "Attendees" to an event.
o Reschedule an existing event.
o Response to a "REFRESH" request.
o Update the details of an existing event, without rescheduling it.
o Update the status of "Attendees" of an existing event, without rescheduling it.
o Reconfirm an existing event, without rescheduling it.
o Forward a "VEVENT" to another uninvited CU.
o For an existing "VEVENT" calendar component, delegate the role of "Attendee" to another CU.
o For an existing "VEVENT" calendar component, change the role of "Organizer" to another CU.
The "Organizer" originates the "REQUEST". The recipients of the "REQUEST" method are the CUs invited to the event, the "Attendees". "Attendees" use the "REPLY" method to convey attendance status to the "Organizer".
The "UID" and "SEQUENCE" properties are used to distinguish the various uses of the "REQUEST" method. If the "UID" property value in the "REQUEST" is not found on the recipient's calendar, then the "REQUEST" is for a new "VEVENT" calendar component. If the "UID" property value is found on the recipient's calendar, then the "REQUEST" is for a rescheduling, an update, or a reconfirmation of the "VEVENT" calendar component.
For the "REQUEST" method, multiple "VEVENT" components in a single iCalendar object are only permitted for components with the same "UID" property. That is, a series of recurring events may have instance-specific information. In this case, multiple "VEVENT" components are needed to express the entire series.
This method type is an iCalendar object that conforms to the following property constraints:

It will process changes made by the organizer, but it will NOT do the following: <ul> <li>Invite "Attendees" to an event. <li>Reconfirm an existing event, without rescheduling it <li> If those features are desired then extend this class and add them.
