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.
com.erudika.para.utils.Pager
This class deals with pagination. It limits the results for queries in the {@link com.erudika.para.persistence.DAO}and {@link com.erudika.para.search.Search} objects and also counts the total number of results that are returned. @author Alex Bogdanovski [alex@erudika.com]
org.apache.tuscany.das.rdb.Pager
An iterator-like interface to conveniently move through chunks of data. The idea is that a Pager works with a read Command. The read command returns a large amount of data and the client wants to work with chunks of it at a time. So the Pager is created on the command and each call to next returns the next chunk of data. This is done completely disconnected. No cursor is maintained between calls to #next. TODO - This is very preliminary. We need to look at this interface in the context of disonnected scenarios such as a web app. The Pager instance will probably be saved in session so it must be very light and cannot reference a connection. Also, we probably need to define a factory or add a method to set page size.

Pager control. To use this control, subscribe to the PagerUpdatedEvent and access the start and end indexes and refresh your data.
