Subject [jira] [Created] (LANG-819) EnumUtils.generateBitVector needs a "? extends"
Date Sun, 09 Sep 2012 18:41:07 GMT
Shevek created LANG-819:
---------------------------

             Summary: EnumUtils.generateBitVector needs a "? extends"
                 Key: LANG-819
                 URL: https://issues.apache.org/jira/browse/LANG-819
             Project: Commons Lang
          Issue Type: Bug
    Affects Versions: 3.0.1
            Reporter: Shevek
            Priority: Minor


    public static <E extends Enum<E>> long generateBitVector(Class<E> enumClass,
Iterable<E> values) {

Should be Iterable<? extends E>.

This is because although no subclasses of E can exist, the "? extends" is a common idiom for
marking the collection as readonly, or not "owned" by the current object.
