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.
