[Collections][SUBMIT] PredicateUtils [was TypedList]
Hi all,
Please find attached PredicateUtils.
PredicateUtils is a single class that provides predicate (validating)
implementations of all java and commons collections:
Collection
List
Set, SortedSet
Map, SortedMap
Bag, SortedBag
It also provides useful predicate classes:
True
False
And
Or
Not
instanceof
To avoid polluting the commons package with the 18 classes necessary to
achieve this, they are all implemented as static nested classes within
PredicateUtils. This is similar to how synchronized and unmodifiable
collections work in java.util.Collections. All the classes are created and
used by static factory methods, except True and False which are constants.
Feedback welcome on the implementation, and indications of acceptability for
actual inclusion in commons.
Stephen

Hi,
Thanks for the cvs add.
Please find attached some basic unit tests for List, Set and Map.

Hi Stephen
I've given the code a quick once-over and it looks great. Nice and clean.
I've added into CVS - if anyone has any objections please speak up.
Some JUnit test cases would be nice for this stuff ;-)
