Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Commons Wiki" for c=
hange notification.

The "Sanity Check of APIs, etc." page has been changed by MattBenson:
http://wiki.apache.org/commons/Sanity%20Check%20of%20APIs%2C%20etc.?action=
=3Ddiff&rev1=3D7&rev2=3D8

     (Same question would apply to -Predicate and -Procedure in addition to=
 -Function) Using a vararg parameter would preclude the binary (and hypothe=
tical ternary, etc.) functors from supporting different strongly typed argu=
ments.  I think it would be a step backward.  MJB

   * '''''EachElement should be able to work on any Iterable. Also I'm not =
sure to understand why its constructor is public.'''''
-    Agreed about the first point; added https://issues.apache.org/jira/bro=
wse/FUNCTOR-13 .  As to why the ctor is public, the javadoc says "This cons=
tructor is public to permit tools that require a JavaBean instance to opera=
te."  Not sure how many tools actually still need this.  Velocity was the p=
rimary suspect for ages; does anyone know if it still needs a bean instance=
? '''UPDATE''' it was quick work to google that Velocity does now support c=
alling static methods, so we can IMO end this practice for current and futu=
re development throughout Commons.

   * '''''Shouldn't Generator implement Iterable?'''''
     It doesn't seem so to me.  It's possible some more expository name cou=
ld be found for Generator.
