UtilProperties Idea - please comment

[Adrian Crum]

I've been working on the UtilProperties class to clean up some of the code, improving the cache
handling algorithm, improve support for i18n, and add support for the new XML properties file format.

I believe we could really improve the performance of OFBiz if we cached FastMap instances instead of
java.util.Properties instances. That would require a slight change in the UtilProperties API -
UtilProperties.getProperties(...) would return a Map instance instead of a Properties instance.

Doing so wouldn't have a large impact on the existing code base - there are only a handful of places
where UtilProperties.getProperties(...) is called. The problem would be legacy installations -
custom code that calls UtilProperties.getProperties(...) would break.

Should I change the existing method signature, or add the new methods and deprecate the old ones?

Adrian,

How about getting FlexibleProperties to implement Map, in addition to Properties?

Jonathon,

Properties extends Map. I ended up having two methods - one that returns a Map in addition to the
original.

I've been using it for nearly a week and everything seems to be working well. I'll post it to Jira
in the next few days.

Adrian,

Method overriding is only possible with different parameters, not with different returns, I believe?

Rather than deprecating one of those 2 methods, might I suggest that you retain just one? One
method that will serve both the old and the new usages.

Here's how it works.

If Properties continues to extend FlexibleProperties, your original method signature works for old
usages. What about the new ones requiring a Map to be returned?

If FlexibleProperties implements Properties, then it can be viewed as a "type of Properties". If
it also implements Map, then it can be cast into a Map!

One class (FlexibleProperties), 2 perspectives. Everybody is happy. :)

Hope that is clear. It's some Java stuff. Check out multiple interfaces for a single class.

Not that you don't know Java (you've certainly done lots for Widget Engine!!). I'm just hoping to
keep the coding as Java-OO as possible. Neat and clean. There are certainly many ways of going
about it.

Oh, I missed this.

Yeah, Properties implements Map. Isn't it possible to get a Properties from method
getProperties(...), and the cast it to a Map?

In FlexibleProperties, override the Hashtable methods in Properties. That is, in
FlexibleProperties, encapsulate one FastMap, and make sure all Map interfaces use that FastMap.

Ignore my post here. See the other one. Even simpler solution.

Jonathon,

Thank you for the ideas. Actually, I ended up getting rid of references to FlexibleProperties - it didn't do anything special and only one other class is using it.

That's a bit destructive.

Last count of usage: Debug, UtilProperties, VelocityViewHandler.

Well, long as it works. :)

No, it's not destructive - the class is still there. It's just that UtilProperties doesn't use it any more.

Oh, ok. I think it's perfectly alright. Have you checked usages of method
UtilProperties.getProperties(...)? Those will need to be changed to expect Map.

If you keep the original getProperties(...), and enhance FlexibleProperties to internally use
FastMap, the change propagation will not be needed.

I've already answered the question I originally posted. The rest of the details will be obvious when I submit the patch. Be patient.

In your original post, you mentioned a concern about breaking legacy codes.

I gave a suggestion that (if I'm not wrong) would fix the concern. Legacy codes will work, nothing
will be broken. Yet, the efficient FastMap will be used. Both ends of spectrum benefit.

I thought you wanted to address that concern.

I'll wait for the patch. :) I'm also currently systematically going through the framework codes.
Nice to see you making enhancements and wrapping up loose ends.
