Class XPojoDataSource

java.lang.Object
  net.xoetrope.data.XDataSource
      net.xoetrope.optional.data.pojo.XPojoDataSource

Direct Known Subclasses:

XPojoHibernateDataSource

public class XPojoDataSource
extends XDataSource

A data source for working with POJOs. When the application is loaded the datasources are instantiated and in the case of a XPojoDataSource the XPojoRoot instance specified by the root element is instantiated and configured. The configuration project involves traversing the class hierarchy and setting up XPojoModel nodes or proxies for each class in the pojo hierarchy. The configuration can specify naming overrides if the names established by reflection are not suitable
