Subject [jira] [Created] (LANG-702) New component for lang -- summarizer
Date Sun, 29 May 2011 13:15:47 GMT
New component for lang -- summarizer

                 Key: LANG-702
             Project: Commons Lang
          Issue Type: New Feature
          Components: General
    Affects Versions: 3.0
            Reporter: Liviu Tudor
            Priority: Minor
             Fix For: 3.x

Hi, I'm creating this as a patch request but I guess really initially I wanted to verify with
everyone that commons lang is the place for this class hierarchy I'm proposing -- and if not
please suggest whether it would be more appropriate to submit this to collections or one of
the other Commons projects. (Or I accept as well the fact that it might not be good enough
for any of the commons projects in which case please just let me know so I won't try to create
new issues around this in the future.)
Basically I've come across a pattern I find myself using a lot in my applications where I
want a quick (and not so dirty) way of monitoring certain things in the application -- for
instance, I want as a quick healthcheck a page to tell me how many requests we process over
a 1 minute interval or so. While one can implement complex monitoring systems to achieve the
same, a lot of the times, simply the fact that the number of successful transactions per minute
goes down to 50% (after an application upgrade for instance) is a clear indicator to me that
something isn't right so I can start investigating straight away and not wait for our monitoring
systems to kick in one hour later or so and alert us of this. As such I have developed this
component which I have called "Summarizer" (purely as my initial request was just to sum up
some numbers over a period of time and reset it regularly -- but as my javadoc comments state,
of course this doesn't have to be a simple arithmetic sum and can be extended to other operations).
The diff I'm proposing here contains the base class and an example of the class using integers
which just sums them up -- which is as I said the kind of implementation that I have found
myself implementing a lot in my apps. I appreciate that the classes are not completely finished
and there are no unit tests yet -- and that is because as I said at this stage I am trying
to figure out whether this component would fit into the Commons Lang component or it would
be more appropriate to commit this somewhere else.
I would appreciate your input/comments on this so I know whether i'm on the right track on
committing this here or should I move it elsewhere; I accept that perhaps the package names
and the class names are not the best, and am willing to discuss with your main committers
around this -- if this proves to be a valid component for commons. 
If you decide this is a good idea to proceed with then I can start adding unit tests and more
comments/javadocs around it to make this into a usable class hierarchy. 
As suggested by your FAQ's I've created a diff from the root of the folder -- if it helps
more if I just provide the 2 classes I can do so too -- just let me know and I can send you
a zip with the 2 classes alone or so.
Looking forward to your comments on this,
