[jira] Closed: (LANG-290) EnumUtils for JDK 5.0
[ https://issues.apache.org/jira/browse/LANG-290?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Stephen Colebourne closed LANG-290.
-----------------------------------
Resolution: Fixed
Renamed isEnum to isValidEnum.
Don't believe that sizeOf is sufficiently commonly needed, and is easy to access by getting the list/array and calling size/length.
