Enum Constant Detail

FIRST

public static final Fn2.Singletons FIRST

A static function that always returns the first argument it is given. For type safety, please use Fn2.first() instead of accessing this dirctly.

SECOND

public static final Fn2.Singletons SECOND

A static function that always returns the second argument it is given. For type safety, please use Fn2.second() instead of accessing this dirctly.

Method Detail

values

public static Fn2.Singletons[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Fn2.Singletons c : Fn2.Singletons.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Fn2.Singletons valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
