public final class CollectionUtils extends Object
Utility class that simplifies creating collections in Java.
Creating Maps
Map m = map() .e("foo", foo) .e("bar", bar);
Creating Lists
List l = list() .e("foo") .e("bar");
Set s = set() .e("foo") .e("bar");

The Map is used live, which means changes made to it will affect the Properties instance directly.
