I am sadly quite clueless when it comes to Java.
De-compiling the Scala class file to Java gives me the following:
public <T> AtomicDist<T> apply(Seq<Tuple2<Object, Element<T>>> clauses,
Name<T> name, ElementCollection collection) {
return new AtomicDist(name, clauses.toList(), collection);
}
public <T> CompoundDist<T> apply(Seq<Tuple2<Element<Object>,
Element<T>>> clauses, Name<T> name, ElementCollection collection) {
return new CompoundDist(name, clauses.toList(), collection);
}
Generics all over the place. Would this even be callable from Java 1.4?
