Creates a ClassNode containing the wrapper of a ClassNode of primitive type. Any ClassNode representing a primitive type should be created using the predefined types used in class. The method will check the parameter for known references of ClassNode representing a primitive type. If Reference is found, then a ClassNode will be contained that represents the wrapper class. For example for boolean, the wrapper class is java.lang.Boolean. If the parameter is no primitive type, the redirected ClassNode will be returned @see #make(Class) @see #make(String) @param cn the ClassNode containing a possible primitive type

Iterates over the elements of an iterable collection of items, starting from a specified startIndex, and returns the index values of the items that match the condition specified in the closure. @param self the iteration object over which to iterate @param startIndex start matching from this index @param closure the filter to perform a match on the collection @return a list of numbers corresponding to the index values of all matched objects @since 1.5.2
