A persistent C++ variant Version 2.3.3 compiler ef="ftp://ftp.cs.wisc.edu/exodus/e/">. GNU e is a persistent, object oriented programming language developed as part of theexodus project. GNU eextends C++ with the notion of persistent data, program level data objects that can be transparently used across multipleexecutions of a program, or multiple programs, without explicit input and output operations. GNU e' s form of ef="module.php?name=Lexikon&file=search&eid=1&query=persistence">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 theexodus 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 theexodus storage manager e-mail: <exodus@cs.wisc.edu>.
