> Project: Commons Functor
> Issue Type: Improvement
> Reporter: Anil K.Kinge
> Assignee: Brent Worden
> Attachments: functors.propertypredicates.new.diff

>
> In my current project I created a set of new Predicates that I call as
> Property Predicates. These predicates can used to filter a collection based
> on property values.
> For example we have :
> Class Foo{
> String name;
> Int age;
> Address address;
> }
> Address{
> String street;
> String zip;
> }
> Collection<Foo> myFoos ;
> And we want to find all the Foo in myFoos with name that starts with A, and
> age > 40 and who are living at Zip 07095 we can create a Predicate like
> follows:
> Predicate p = new PropertyLikePredicate("name","A*")
> .andGreaterThan("age",40)
> .andEquals(address.zip,"07095");
> Note: Like supports wildcards '*' and '?'
> What is even better is that these predicates work with collections too. What
> I mean is if we have :
> FooBar{
> String name;
> Collection<Address> addresses;
> }
> And you want to locate someone with a zip 07095 as part of anyof its'
> addresses all we need is to create a predicate :
> Predicate p = new PropertyEqualsPredicate("addresses[].zip","07095");
> My Predicate chain currently supports the following features:
> 1. andEquals
> 2. orEquals
> 3. andNotEquals
> 4. orNotEquals
> 5. andLike
> 6. orLike
> 7. andGreatorThan
> 8. orGreatorThan
> 9. andGreatorThanOrEquals
> 10. orGreatorThanOrEquals
> 11. andLessThan
> 12. orLessThan
> 13. andLessThanOrEquals
> 14. orLessThanOrEquals
> 15. isNull
> 16. isNotNull
> 17. orNull
> 18. orNotNull
> 19. orNullOrEmpty
> 20. orNotNullOrEmpty
> 21. andNullOrEmpty
> 22. andNotNullOrEmpty
> All features have accompanying testcases. In my opinion this is a powerful
> addition to the functors and I would like to contribute this work to the
> commons-collection.
