Class JpaPagination

java.lang.Object
org.europa.together.domain.JpaPagination
public class JpaPagination extends Object
Be always aware, when using listAll() because some database tables with a giant amount of rows will slow down your application dramatically. The JpaPagination is designed to limit your result set. It avoid a slow performing OFFSET and implement instead the seek method.
To secure a correct result set, the results aer by default sorted by the primary key of the database table in an ascending manner. This behavior can be changed.
Its necessary to define the Primary Key from the Domain Object and not from the database table name.
