Bruno P. Kinoshita commented on FUNCTOR-26:
-------------------------------------------

Hi, after inspecting the patch, I agree with [~scolebourne]. The main class, 
responsible for testing the predicates is PropertyPredicate, which has a 
dependency on [beanutils]. I believe it would make more sense to keep this code 
in [beanutils] and, maybe in the future, use some of the [functor] interfaces. 
Any thoughts on this?

> 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.
