Uses of Function in com.google.common.collect

Methods in com.google.common.collect with parameters of type Function

<K,V,E> java.util.concurrent.ConcurrentMap<K,V>	CustomConcurrentHashMap.Builder.buildComputingMap(CustomConcurrentHashMap.ComputingStrategy<K,V,E> strategy, Function<? super K,? extends V> computer) Creates a ConcurrentMap, backed by the given strategy, that supports atomic, on-demand computation of values.
V	CustomConcurrentHashMap.ComputingStrategy.compute(K key, E entry, Function<? super K,? extends V> computer) Computes a value for the given key and stores it in the given entry.
static <K,V> ListMultimap<K,V>	Multimaps.index(java.lang.Iterable<? extends V> values, Function<? super V,? extends K> keyFunction) Creates an index ListMultimap that contains the results of applying a specified function to each item in an Iterable of values.
static <K,V> void	Multimaps.index(java.lang.Iterable<? extends V> values, Function<? super V,? extends K> keyFunction, Multimap<K,V> multimap) Indexes the specified values into a Multimap by applying a specified function to each item in an Iterable of values.
<K,V> java.util.concurrent.ConcurrentMap<K,V>	MapMaker.makeComputingMap(Function<? super K,? extends V> computer) See CustomConcurrentHashMap.Builder.buildComputingMap( CustomConcurrentHashMap.ComputingStrategy, com.google.common.base.Function).
<F> Ordering<F>	Ordering.onResultOf(Function<F,? extends T> function) Returns a new ordering on F which orders elements by first applying a function to them, then comparing those results using this.
static <F,T> java.lang.Iterable<T>	Iterables.transform(java.lang.Iterable<F> fromIterable, Function<? super F,? extends T> function) Returns an iterable that applies function to each element of fromIterable.
static <F,T> java.util.Iterator<T>	Iterators.transform(java.util.Iterator<F> fromIterator, Function<? super F,? extends T> function) Returns an iterator that applies function to each element of fromIterator.
static <F,T> java.util.List<T>	Lists.transform(java.util.List<F> fromList, Function<? super F,? extends T> function) Returns a list that applies function to each element of fromList.
static <K,V1,V2> java.util.Map<K,V2>	Maps.transformValues(java.util.Map<K,V1> fromMap, Function<? super V1,V2> function) Returns a view of a map where each value is transformed by a function.
static <K,V> ImmutableMap<K,V>	Maps.uniqueIndex(java.lang.Iterable<? extends V> values, Function<? super V,K> keyFunction) Returns an immutable map for which the Map.values() are the given elements in the given order, and each key is the product of invoking a supplied function on its corresponding value.
