Method

ListcastList(Class clazz, Collection c)
This method verifies the content of a list. 
List<T> r = new ArrayList<T>(c.size());
for (Object o : c)
    r.add(clazz.cast(o));
return r;
ListcastList(Class clazz, Collection c)
cast List 
List<T> r = new ArrayList<T>(c.size());
for (Object o : c)
    r.add(clazz.cast(o));
return r;
ListcastList(Class clazz, Collection collection)
Casts a raw Collection to a generic List . 
List<T> genericList = new ArrayList<T>(collection.size());
for (Object object : collection) {
    genericList.add(clazz.cast(object));
return genericList;
ListcastList(Class elementType, List list)
cast List 
if (list == null) {
    return null;
for (Object element : list) {
    if (!elementType.isAssignableFrom(element.getClass())) {
        throw new Exception("List element has invalid type -- expected '" + elementType.getName()
                + "', got: " + element.getClass().getName());
return (List<T>) list;
ListcastList(Class klass, List list)
cast List 
return castList(klass, list, false);
ListcastList(Collection c)

if (c instanceof List)
    return (List<T>) c;
else
    return new ArrayList<T>(c);
ListcastList(final List original)
Convert a list of type List to List if the cast is acceptable for all elements of the input list. 
List<T> result = new ArrayList<T>();
for (E record : original)
    result.add((T) record);
return Collections.unmodifiableList(result);
ListcastList(final Object object)
Cast Object to List . 
return (List<T>) object;
ListcastList(List list, Class clazz)
Casts a list containing elements of class T to a list containing elements of a subclass E. 
return (List<E>) list;
ListcastListElem(List list, V target)
Creates a new list of the objects cast as the type passed as target. 
List<V> result = new ArrayList<V>(list.size());
for (T elem : list) {
    result.add((V) elem);
return result;
