I have a list of objects of class X. X has a unique identifier property
P. Given a value p, I want to see if the list contains an object
where x.P = p. Very simple, I ended up using a for loop to iterate over
the objects in listX, breaking when I found the first occurrence.
Before doing that, however, I tried to find something in Commons that
would do this for me. The closest I could find was
org.apache.commons.collections.CollectionUtils.find(java.util.Collection
collection, Predicate predicate). However, I couldn't find a simple
PropertyPredicate that allowed me to say "look for objects whose
property P is p". That seems like one of the most obvious uses of find,
so I believe I'm just not looking in the right place.
I'd appreciate a pointer to where I can find this. Thanks.
