Better EnumUtils
----------------
Key: LANG-513
URL: https://issues.apache.org/jira/browse/LANG-513
Project: Commons Lang
Issue Type: Improvement
Affects Versions: 3.0
Reporter: Ivan Bilenjkij
Fix For: 3.0
Parametrize the getEnumMap() method with <E extends Enum<E>>. This narrows
down the argument so that non-enums and {{null}} are rejected at compile time.
Also, at it current state the EnumUtils should never be instantiated.
{code:title=EnumUtils.java} public static Map<String, Enum<?>> getEnumMap(Class
enumClass) {code}
changes to:
{code:title=EnumUtils.java} public static <E extends Enum<E>> Map<String,
Enum<E>> getEnumMap(Class<E> enumClass) {code}
