This method creates a copy of the internal storage structure so changes to the returned collection are allowed.
Function<String,E> stringToEnum()
String and converts it into an enum for
this field.
The function should return null if a null value is
specified as input and throw an exception if the value is invalid.
Function<E,String> enumToString()
String.
The function should return null if a null value is
specified as input and throw an exception if the value is invalid.
