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: .
