Examples of com.adito.table.Pager

com.adito.table.Pager
Provides an additional layer over a {@link com.adito.table.TableItemModel} that allows the items within themodel to be displayed a page at a time.
The pager also deals with the sorting of the displayed items as well as filtering, leaving the contents of the model alone.

            Pager pager = resourcesForm.getPager();


            int filteredRowCount = pager.getFilteredRowCount();
            final int expectedRowCount = getInitialResourceCount() + 15;
            assertEquals("Should have " + expectedRowCount + " row(s)", expectedRowCount, filteredRowCount);
