Method Detail

getById

public static <I,E extends Enum<E> & IdLookup<I>> E getById(Class<E> clazz,
                                                            I id)

Parameters:

clazz - an Enum class implementing IdLookup<I>

id - an instance of type I

Returns:

the instance e of class clazz such that e.getId().equals( id )

getByCode

public static <S,E extends Enum<E> & CodeLookup<S>> E getByCode(Class<E> clazz,
                                                                S code)

Parameters:

clazz - an Enum class implementing CodeLookup<S>

code - an instance of type S

Returns:

the instance e of class clazz such that e.getCode().equals( code ), unless S is String, in which case equalsIgnoreCase is used instead of equals().

getByIds

public static <I,E extends Enum<E> & IdLookup<I>> List<E> getByIds(Class<E> clazz,
                                                                   List<I> ids)
