Method Detail

identity

public static <E> Function<E,E> identity()

Returns the identity function.

toStringFunction

public static Function<java.lang.Object,java.lang.String> toStringFunction()

Returns a function that calls toString() on its argument. The function does not accept nulls; it will throw a NullPointerException when applied to null.

Warning: The returned function may not be consistent with equals (as documented at Function.apply(T)). For example, this function yields different results for the two equal instances ImmutableSet.of(1, 2) and ImmutableSet.of(2, 1).
