A persistent C++ variant Version 2.3.3 compiler . GNU E is a persistent, object ORiented programming language developed as part of the Exodus project. GNU E extends C++ with the notion of persistent data, program level data objects that can be transparently used across multiple executions of a program, OR multiple programs, without explicit input and output operations. GNU E' s fORm of persistence is based on extensions to the C++ type system to distinguish potentially persistent data objects from objects that are always memORy resident. An object is made persistent either by its declaration (via a new "persistent" stORage class qualifier) OR by its method of allocation (via persistent dynamic allocation using a special overloading of the new operatOR). The underlying object stORage system is the Exodus stORage manager, which provides concurrency control and recovery in addition to stORage fOR persistent data. restriction: Copyleft not all run-time sources are available (yet) requires: release 2.1.1 of the Exodus stORage manager E-mail: .
