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.
