Does he actually need a real arraylist, or will something fulfilling a collection interface (Collection, Iterable, or List for example) be ok? Many clojure types do not require any casting at all as long as the java code writes to a collection interface and doesn't expect to be able to mutate the object. (Both of these are good Java idioms: write to interfaces not classes, and copy defensively.)
So if your coworkers code just needs something iterable (for example), you may not need to do any casting at all: just give him the vector. If your coworker's code needs a real ArrayList and can accept no substitutes, (java.util.ArrayList. your-vector) will make an ArrayList copy of a vector's contents. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
