Functional programming in Java

From: "andrew cooke" <andrew@...>

Date: Wed, 1 Mar 2006 12:49:18 -0300 (CLST)

I needed a filter for a list.  Rather than reinvent the wheel I downloaded
FunctionalJ - http://functionalj.sourceforge.net/

It's not amazingly elegant (you need to name methods as strings, for
example), but it does the job.  Here's the final code:

  @SuppressWarnings("unchecked")
  public static List<? extends LifetimeAccessControl>
  filterValid(List<? extends LifetimeAccessControl> list) {
    return Functions.filterNot(
      new InstanceFunction(LifetimeAccessControl.class, "isExpired"), list);
  }

Lists only

From: "andrew cooke" <andrew@...>

Date: Fri, 3 Mar 2006 09:17:01 -0300 (CLST)

I forgot to mention that for some crazy reason the library only works on
lists.  Given Java has the generic iterators that are supported by every
collection you'd think that all collection types would be supported.  Very
odd indeed.

[The latest version also supports generics; it also has some new
reflection functionality that might address the "strings" issue I
mentioned above; Frederic's support for this package is very good -

Hi Andrew,

Came across this on your blog:

Indeed, very odd that I did that. I corrected this in version 0.8 - now
the library uses collections. If I overlooked it somewhere please let me
know.

Also other comments or suggestions are always welcome..

Cheers,
Frederic
