Uses of Function in com.google.common.collect
 

Methods in com.google.common.collect with parameters of type Function
static
<K,V> ImmutableListMultimap<K,V>
Multimaps.index(Iterable<V> values, Function<? super V,K> keyFunction)
          Creates an index ImmutableMultimap that contains the results of applying a specified function to each item in an Iterable of values.
<K,V> ConcurrentMap<K,V>
MapMaker.makeComputingMap(Function<? super K,? extends V> computingFunction)
          Builds a map that supports atomic, on-demand computation of values.
<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> Collection<T>
Collections2.transform(Collection<F> fromCollection, Function<? super F,T> function)
          Returns a collection that applies function to each element of fromCollection.
static
<F,T> Iterable<T>
Iterables.transform(Iterable<F> fromIterable, Function<? super F,? extends T> function)
          Returns an iterable that applies function to each element of fromIterable.
static
<F,T> Iterator<T>
Iterators.transform(Iterator<F> fromIterator, Function<? super F,? extends T> function)
          Returns an iterator that applies function to each element of fromIterator.
static
<F,T> List<T>
Lists.transform(List<F> fromList, Function<? super F,? extends T> function)
          Returns a list that applies function to each element of fromList.
static
<K,V1,V2> Map<K,V2>
Maps.transformValues(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(Iterable<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.
