Multiple GoodData REST resources return results in the form of pages. Each page contains limited number of records and a URL link to next page (except the last page).
GoodData Java SDK encapsulates this resources as listItem(Page page)
methods:
- paging can be controlled by the
Page
argument - eg.listItem(new PageRequest(10))
lists 10 items per page - the return type is
PageableList<Item>
which represents a page returned from REST resource - the
PageableList
class has methodsboolean hasNextPage()
andPage getNextPage()
which can be used to iterate thru all pages - the paging flow can be simplified using
PageableList
's iterator which transparently loads subsequent pages, so eg. for each loop iterates thru all pages - Java Stream API is supported, so when
PageableList.stream()
is used, it processes all the items including those on subsequent pages - to work only with items on the current page use
list.getCurrentPageItems()
method
