Examples of PagerModel

org.apache.beehive.netui.databinding.datagrid.api.pager.PagerModel
The PagerModel is a JavaBean that represents the page state of a data grid. In the default implementation, the page state consists of three pieces of data:
- the current row
- current page
- the href / action used to page through data
This pager model implementation is row based which means that the notion of the current page is based on which row is at the top of a page. Row numbering starts at zero and continues to page size. For example, in a data grid on its first page and with a page size of 10, the rows 0-9 will be displayed. The next page would contain rows 10-11 and so on.

The pager model provides JavaBean-style access to the properties of a pager. In addition, it provides read-only access to information about the row to use in order to navigate to a specific page. To navigate to the previous page, the {@link #getRowForPreviousPage()} will return the row number that will appear at the top of the previouspage. In order to build effective paging UI, it is also often useful to know the absolute page number. As with row numbers, page numbers are zero based. For example, if a data set displayed in a data grid has 30 records and the grid is on page a page displaying rows 10-19, the current page is 1. When displaying this value in UI, it is often useful to display it as:
```
 Page 2 of 3 
```
Random page access can also be accomplished using the {@link #encodeRowForPage(int)} method which will returnthe row number to display when jumping to a specific page in a grid.
