public abstract class PaginationController
extends AjaxFormController

Pagination Controller's default implementation assumes that successView points to a JSP that contains a div whose sole contents are a that includes the same JSP as ajaxView. Inside ajaxView is the The most basic implementation only needs to implement populatePaginatedList, setting the list on the default PaginationCommandObject. For more advanced pagination scenarios, such as search strings, filters, or sorting, PaginationControllerObject should be subclassed and formBackingObject overriden. To populate additional elements of the model, override populateStandard and call super.populateStandard.

Method Detail

getPaginationObjectName

public java.lang.String getPaginationObjectName()

setPaginationObjectName

public void setPaginationObjectName(java.lang.String paginationObjectName)

The name by which the PaginationCommandObject will be named for the jsp.

Parameters:

paginationObjectName -

populatePaginatedList

protected abstract void populatePaginatedList(java.util.Map<java.lang.String,java.lang.Object> model,
                                              PaginationCommandObject object)

populatePaginatedList is where the logic to retrieve the list items is implemented. There are two strategies, pulling all items or only pulling the displayed subset. The easiest to implement is to retrieve all items that are in the list and call PaginationCommandObject.setFullList, and the paginatedList will determine what items to display. For expensive retrievals of large lists, only pull the PaginationCommandObject.getPageSize() subset starting at PaginationCommandObject.getStartIndex(). If using setDisplayList, the next button will not display unless PaginationCommandObject.setListSize is called with a number greater then or equal to PaginationCommandObject.getEndIndex()

Parameters:

model -

object -
