public abstract class AbstractRepeater extends WebMarkupContainer
renderIterator() method. This class will take care of
properly positioning and rewinding its markup stream so before each child renders it points to
the beginning of this component. Each child is rendered by a call to
renderChild(Component). A typical implementation simply does
child.render();.
Note: the children are added during the render phase (in Component.beforeRender() so
most of the specializations of this class should not be used as parents of
FormComponents in stateless pages because the form components
will not be available during the action phase (i.e. at
Form.onSubmit()). Use
RepeatingView in these cases.ENABLE, FLAG_AFTER_RENDERING, FLAG_INITIALIZED, FLAG_PREPARED_FOR_RENDER, FLAG_REMOVING_FROM_HIERARCHY, FLAG_RENDERING, FLAG_RESERVED1, FLAG_RESERVED2, FLAG_RESERVED3, FLAG_RESERVED4, FLAG_RESERVED5, FLAG_RESERVED8, PARENT_PATH, PATH_SEPARATOR, RENDER, RFLAG_CONTAINER_DEQUEING| Constructor and Description |

NOTE: If you override this, you *must* call super.onBeforeRender() within
your implementation.
Because this method is responsible for cascading Component.onBeforeRender() call to its
children it is strongly recommended that super call is made at the end of the override.

MarkupContainerMarkupContainer.queue(Component...). It then delegates the
dequeueing to these children.
Certain components that implement custom markup behaviors (such as repeaters and borders)
override this method to bring dequeueing in line with their custom markup handling.dequeue in class MarkupContainerdequeue - the dequeue context to useCopyright © 2006–2018 Apache Software Foundation. All rights reserved.
