[lang] Interpolation
Hello,
I'm just taking a quick look at Interpolation.
(1) Does it belong?
I was at first a little surprised to see something so script-like in
[lang]. I guess it does not feel like something that is missing in
java.lang. OTOH, we are just talking about another form of String search
and replace, so it does make sense under that umbrella.
(2) The name Interpolation and interpolate.
I must say that I am a bit turned off by these somewhat mathematical
names. This class is more of String "matcher" or "replacer" thingy. What
does Ant call these things?
Interpolation.interpolate( templateString, valuesMap );
(3) Usage.
I'd like that class to be more flexible in order to do the following for
example:
Interpolation interpolation = new Interpolation();
interpolation.setStartMarker("<");
interpolation.setEndMarker(">");
interpolation.setMap(aMap);
String news = interpolation.interpolate(templateString);
Cheers,
Gary

Interpolation is well understood by Perl programmers. It's probably a
good idea to use a term that many other people already know. Of course,
if it doesn't really do interpolation in the Perl sense of the word an
alternate name would be a good idea to prevent confusion.

Used to be a class in Util, but we didn't want it in Lang. Someone posted
a patch for a similar thing for StringUtils and so I merged it in with the
Util one and added it into Lang awaiting opinion.
It's a pretty basic and common thing I think.

Perl/unix-y script calls it interpolating I think. That's why I've used
that term :)

Sounds interesting. ${..} seems a common default though.
