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.

Bindings

displayGroup	the display group to paginate
displayName	the name of the items that are being display ("photo", "bug", etc)
showPageRange	if true, the page of items on the page is shown, for example "(1-7 of 200 items)"
showBatchSizes	if true, a menu to change the items per page is shown "Show: (10) 20 (100) (All) items per page"
batchSizes	can be either a string or an NSArray of numbers that define the batch sizes to chose from. The number "0" provides an "All" items batch size. For example "10,20,30" or "10,50,100,0"
small	if true, a compressed page count style is used
parentActionName	(if you don't provide a displayGroup) the action to be executed on the parent component to get the next batch of items.
currentBatchIndex	(if you don't provide a displayGroup) used to get and set on the parent component the selected page index
maxNumberOfObjects	(if you don't provide a displayGroup) used to get the total number of objects that are being paginated.
numberOfObjectsPerBatch	(if you don't provide a displayGroup) the number of objects per batch (page)
