  • Field Details

    • _valueLookup

      private static final Month[] _valueLookup
      The implementation of the functions to convert to and from calendar values assume that neither the values in java.util.Calendar nor the order of constants in this enumeration will ever change. The _valueLookup array is just a private cache of the enumeration value array to avoid allocating a new one every time we do a lookup.
