1. Object Euphoria

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.

Object Euphoria is a comprehensive, Java-like Object Oriented =
Programming (OOP) system.  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!

Let me know what you think about this.

Mike:

Indexed_sequence is type defined in both stdcont.ec and demo.ex

so when the stdcont.ec is included in demo.ex it causes an error

I inadventenly included an old version of stdcont.ec in objecteu.zip--the
new version works correctly.

5. Object Euphoria

------=_NextPart_000_0058_01BF1803.1FAD8FE0
        charset="iso-8859-1"
Content-Transfer-Encoding: quoted-printable

For anybody out there still interested in OOP, I have just completed =
coding Object Euphoria, a very comprehensive Java-model OOP system for =
Euphoria.  Features include:

1.  Java-style classes with single inheritance and interfaces.

2.   Exceptions for error handling--vast improvement over my previous =
submissions in this area.

3.  Object and class members (data) and methods (routines).

4.  Normal, abstract (must be subclassesed to create objects), and final =
(cannot be subclassed) classes.

5.  Normal, abstract (must be overridden), and final (cannot be =
overidden) methods.

6.  Public, protected, and private access for members and methods.

7.  Separate read and write access for members.

8.  Special read-only write access for members to define constants.

9.  Optional constructors and destructors with access control.

10.  All this in a 39K include file!

I am currently doing testing, coding standard classes, writing =
documentation, and working on demo ideas.  I will upload to RDS when I =
have it finished.  I eventually plan to write an Object Euphoria
wrapper for VEL, similar to David Cuny's Llama for Win32.  I may also =
try a preprocessor version of Object Euphoria with dot notation,etc.
