Java template programming

[Mr B.]

Hi gurus

I have a C++ template for handling lists I use. It supports practically any
datatype, sorting, undo, commit, etc etc.....
Is it possible to convert/port/whatever to java, or is there any classes
availble for this
Especially undo and commit are key functionality

TIA
LB

For C++ template like functionality you need to use Java 1.5.

The rest is just code.

Sorry for probably asking an obvious question
If I enter something like this

template < typename AnyData > class GList {

I get a gazillion error messages ( NeBeans 3.6 )

Any help on this ?

Yes, you must write in Java, not C++.
It is a DIFFERENT language. Java is similar to C/C++ at the
statement level, but differs in its object/class model.

Thanks for the link, very usefull...

The examples does not compile, but I checked, and it seems I have java
1.4.xxxx or something, does that mean that I can NOT use templates, the
previous poster said I needed 1.5 ?

And updating is not possible Im afraid !

TIA

Hello Mr. B.

Generics was just added in 1.5. You can download it from Sun's site:
http://java.sun.com/.

The install is very easy.

Let's start with what Java already provides you.

Have you checked the java.util.List interface and the classes
that implement it (ArrayList, LinkedList and Vector). Does your
own list implementation provide anything (besides transaction
support) that is not implemented by those classes?

If no, is it possible for you to implement your transaction
functionality on top of the standars Java lists by using the
"decorator" design pattern?
