I've been working on my FeatureCache and I've got a couple of questions
about the FeatureCollection interface.
Three of the methods of the interface return instances of
java.util.Collection. The getFeatures() method and the query() methods
return instances of java.util.List, while the remove() method returns an
instance that implements the java.util.Collection interface. I am wondering
why these three methods don't consistently return instances of
java.util.List or instances of java.util.Collection. Why is the return value
of the remove() method different from the other two methods?
I also noted that there are three methods that perform removal of Feature
objects from the FeatureCollection, but only one of these methods, the
remove(Envelope env) method, returns the Feature objects removed as an
instance of java.util.Collection. The remove(Feature feature) method and the
removeAll(Collection features) method do not return the Features removed. Is
there a reason why this behavior is not consistent?
I'm just curious. It seems the Vivid Solutions team always had reasons for
doing things that aren't readily apparent because of my lack of programming
experience.
Thank you an advance for any clarification.
