Re: Some idea on extending Pivot collections

[Bill van Melle <bi...@gmail.com>]

I've used these kinds of operations in C# for a long time, and they're
certainly useful.  C# benefits from using Scala's compact syntax (not to
mention real closures), but I think even in the more verbose Java syntax
your proposals could make a programmer's intentions clearer than the
traditional loop style.  I've been porting some C# code to Pivot recently
and wished I had a few of those mapping methods available to me. So I say go
for it.

p.s. I really wish the Pivot List implemented a few more of the operations
that java.util.List implements.  You note *addAll*, which is often useful;
even more so I'd like *contains*, which I use often enough that I wrote my
own static utility method for it.

Hi all,
just created the issue, for the 2.1 :
https://issues.apache.org/jira/browse/PIVOT-799

Bill (and others), if you have some comment/idea/code please post/attach there.

Thank you,
Sandro
