Some info about Object Euphoria: Object Euphoria is very full-featured and secure--it is also god-awful slow. Some benchmarks: Euphoria Object Euphoria 1,000,000 writes 0.01 s 37.80 s 1,000,000 reads 0.01 s 38.06 s 1,000 routine calls 3.08 s 3.13s These are for Object Euprhoria v1.0 on Recent Contributions-- some simple optimiztions have cut the read and write numbers to about 27 seconds. I will agressively optimize the code and publish v1.1 with benchmarks ASAP. OE will still be slow, and any full-featured OOP system will be. If Rob implements namespaces and structures I can and will write a MUCH faster OOP system. I must mention Rod Jackon's excellent Quartz. Quartz does not provide access control-- all data members are public and can be read/written to directly without using the Quartz routines. (Rod's documentation warns not to do this.) So I don't consider Quartz to be full-featured. But it is fast: benchmarks are 1.54 s,1.05s, and 3.08s for writes, reads, and calls. --Mike Nelson

Features include: JAVA-style OOP with single inheritance and interfaces. Run-time polymorphism. Exception handling is provided for error recovery. Normal, final (cannot be subclassed), and abstract (must be subclassed = to be used) classes. Normal, final (cannot be redefined by subclasses), and abstract (must be = redefined by subclasses) methods. Members, methods, constructors, and destructors may have public, = protected, or private access. Read access and write access for members may be specified separately. Write access for members may be READ_ONLY, allowing a member to be = initialized but not changed later. Object and class members and methods. Objects can only be accessed through the routines provided by Object = Euphoria, direct access is impossible, providing excellent security. Namespaces for classes to avoid name clashes in OOP code. All this in a 45KB include file!
