Class Description

EOArrayDataSource is a concrete subclass of EODataSource that can be used to provide enterprise objects to a display group (EODisplayGroup from EOInterface or WODisplayGroup from WebObjects) without having to fetch them from the database. In an EOArrayDataSource, objects are maintained in an in-memory NSArray.

EOArrayDataSource can fetch, insert, and delete objects-operations it performs directly with its array. It can also provide a detail data source.
