public class ERXFlickrBatchNavigation
- extends ERXComponent
ERXFlickrBatchNavigation is a batch navigation component that provides
pagination that behaves like the paginator on Flickr.com.
Include ERXFlickrBatchNavigation.css in ERExtensions for a default stylesheet
that looks (very) similar to Flickr.
Can also be used for pagination on the parent component, where the objects being paginated may be POJOs in an array,
or where paging all the objects in the allObjects array is not feasible due to memory requirements.
