Method Detail

valueOfInsensitive

public static <E extends Enum<E>> E valueOfInsensitive(Class<E> klass,
                                                       String text)

valueOf

public static <E extends Enum<E>,T> E valueOf(Class<E> klass,
                                                    IFunction1<? super E,? extends T> represent,
                                                    boolean ignoreNull,
                                                    IFunction1<? super T,? extends T> mangle,
                                                    T value)

Determine which member of an enum matches value.

Type Parameters:

E - The enum type.

T - The value type, and the type used to represent enum elements (e.g. String)

Parameters:

klass - The enum type.

represent - A function to convert enum members to the representation on which we'll try to match them.

ignoreNull - Should enum members whose representation is null be ignored? If so, those members will never be returned by this method.

mangle - A function to mangle representations, both generated by represent and the text. Can be used to implement case insensitive matching for example.

value - The representation to match.

Returns:

The enum member which matched value.

Throws:

IllegalArgumentException - if the enum members are not unique under represent and mangle.

IllegalArgumentException - if the value does not match any enum member.

getEnumClass

public static <E extends Enum<E>> Class<E> getEnumClass(E object)
