public class Fragment extends WebMarkupContainer implements IQueueRegion
Fragments provide a means to maintain the panels tiny piece of markup. Since it can be anywhere, the component whose markup contains the fragment's markup must be provided (markup provider).

Component.getMarkupSourcingStrategy() returns null, this method will be called. By default
it returns null, which means that a default markup strategy will be attached to the
component.
Please note that markup source strategies are not persisted. Instead they get re-created by calling this method again. That's ok since markup sourcing strategies usually do not maintain a state.

public DequeueContext newDequeueContext()
IQueueRegionDequeueContext that will be used to dequeue children of this region.
Usually containers will create a context with their associated markup by getting it via
MarkupContainer.getAssociatedMarkup(), but components that do not render markup in a
standard way (such as repeaters and borders) may choose to override this method to implement
custom behavior for the dequeueing process.newDequeueContext in interface IQueueRegionnewDequeueContext in class MarkupContainerIQueueRegion.newDequeueContext()Copyright © 2006–2018 Apache Software Foundation. All rights reserved.
