@GwtIncompatible
public static Field getField(Enum<?> enumValue)

  - getIfPresent
```
public static <T extends Enum<T>> Optional<T> getIfPresent(Class<T> enumClass,
                                                           String value)
```
    Returns an optional enum constant for the given type, using Enum.valueOf(java.lang.Class<T>, java.lang.String). If the constant does not exist, Optional.absent() is returned. A common use case is for parsing user input or falling back to a default enum constant. For example, Enums.getIfPresent(Country.class, countryInput).or(Country.DEFAULT);

  - stringConverter
```
public static <T extends Enum<T>> Converter<String,T> stringConverter(Class<T> enumClass)
```
    Returns a converter that converts between strings and enum values of type enumClass using Enum.valueOf(Class, String) and Enum.name(). The converter will throw an IllegalArgumentException if the argument is not the name of any enum constant in the specified enum.
