Uses of Function in dev.mccue.guava.base

Classes in dev.mccue.guava.base that implement Function

Modifier and Type	Class	Description
class	Converter<A,B>	A function from A to B with an associated reverse function from B to A; used for converting back and forth between different representations of the same information.

Methods in dev.mccue.guava.base that return Function

Modifier and Type	Method	Description
static <A extends @Nullable Object, B extends @Nullable Object, C extends @Nullable Object> Function<A,C>	Functions.compose(Function<B,C> g, Function<A,? extends B> f)	Returns the composition of two functions.
static <E extends @Nullable Object> Function<@Nullable Object,E>	Functions.constant(E value)	Returns a function that ignores its input and always returns value.
static <K extends @Nullable Object, V extends @Nullable Object> Function<K,V>	Functions.forMap(Map<K,? extends V> map, V defaultValue)	Returns a function which performs a map lookup with a default value.
static <K extends @Nullable Object, V extends @Nullable Object> Function<K,V>	Functions.forMap(Map<K,V> map)	Returns a function which performs a map lookup.
static <T extends @Nullable Object> Function<T,Boolean>	Functions.forPredicate(Predicate<T> predicate)	Creates a function that returns the same boolean output as the given predicate for all inputs.
static <F extends @Nullable Object, T extends @Nullable Object> Function<F,T>	Functions.forSupplier(Supplier<T> supplier)	Returns a function that ignores its input and returns the result of supplier.get().
static <E extends @Nullable Object> Function<E,E>	Functions.identity()	Returns the identity function.
static <T extends @Nullable Object> Function<Supplier<T>,T>	Suppliers.supplierFunction()	Returns a function that accepts a supplier and returns the result of invoking Supplier.get() on that supplier.
static Function<Object,String>	Functions.toStringFunction()	A function equivalent to the method reference Object::toString, for users not yet using Java 8.

Methods in dev.mccue.guava.base with parameters of type Function

Modifier and Type	Method	Description
static <A extends @Nullable Object, B extends @Nullable Object, C extends @Nullable Object> Function<A,C>	Functions.compose(Function<B,C> g, Function<A,? extends B> f)	Returns the composition of two functions.
static <A extends @Nullable Object, B extends @Nullable Object> Predicate<A>	Predicates.compose(Predicate<B> predicate, Function<A,? extends B> function)	Returns the composition of a function and a predicate.
static <F extends @Nullable Object, T extends @Nullable Object> Supplier<T>	Suppliers.compose(Function<? super F,T> function, Supplier<F> supplier)	Returns a new supplier which is the composition of the provided function and supplier.
static <A, B> Converter<A,B>	Converter.from(Function<? super A,? extends B> forwardFunction, Function<? super B,? extends A> backwardFunction)	Returns a converter based on separate forward and backward functions.
final <F> Equivalence<F>	Equivalence.onResultOf(Function<? super F,? extends @Nullable T> function)	Returns a new equivalence relation for F which evaluates equivalence by first applying function to the argument, then evaluating using this.
abstract <V> Optional<V>	Optional.transform(Function<? super T,V> function)	If the instance is present, it is transformed with the given Function; otherwise, Optional.absent() is returned.
