The Schedule
component provides a calendar to manage events, such as Outlook Calendar and iCal. By default, a whole set of events is eagerly provided via the ScheduleModel
class. That means all events are loaded at once on page load. The lazy loading feature helps to improve performance if we have a huge dataset of events or if events take too much time to load. In the lazy loading mode, only events that belong to the displayed timeframe are fetched.
In this recipe, we will implement a small example for the Schedule
component's lazy loading feature.
A basic definition of schedule
would be as shown here:
<p:schedule id="lazySchedule" value="#{scheduleBean.lazyScheduleModel}"/>
The visual output of the component with two randomly generated events will be as shown here:
By default, the month view is displayed, so the user sees a whole month and can switch between months. Assume that we have to load events for 12 months...
