GNU E

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.
