flip

public com.gs.collections.api.multimap.sortedset.ImmutableSortedSetMultimap<V,K> flip()

Description copied from interface: com.gs.collections.api.map.MapIterable

Given a map from Domain -> Range return a multimap from Range -> Domain. We chose the name 'flip' rather than 'invert' or 'transpose' since this method does not have the property of applying twice returns the original.

Since the keys in the input are unique, the values in the output are unique, so the return type should be a SetMultimap. However since SetMultimap and SortedSetMultimap don't inherit from one another, SetMultimap here does not allow SortedMapIterable to have a SortedSetMultimap return. Thus we compromise and call this Multimap, even though all implementations will be a SetMultimap or SortedSetMultimap.

public com.gs.collections.api.tuple.Pair<K,V> detect(com.gs.collections.api.block.predicate.Predicate2<? super K,? super V> predicate)

Description copied from interface: com.gs.collections.api.map.MapIterable

Return the first key and value of the map for which the predicate evaluates to true when they are given as arguments. The predicate will only be evaluated until such pair is found or until all of the keys and values of the map have been used as arguments. That is, there may be keys and values of the map that are never used as arguments to the predicate. The result is null if predicate does not evaluate to true for any key/value combination.

e.g.
 peopleByCity.detect(new Predicate2<City, Person>()
 {
     public boolean accept(City city, Person person)

flatCollect

public <R> com.gs.collections.api.list.ImmutableList<R> flatCollect(com.gs.collections.api.block.function.Function<? super V,? extends java.lang.Iterable<R>> function)

Description copied from interface: com.gs.collections.api.RichIterable

flatCollect is a special case of RichIterable.collect(Function). With collect, when the Function returns a collection, the result is a collection of collections. flatCollect outputs a single "flattened" collection instead. This method is commonly called flatMap.

Consider the following example where we have a Person class, and each Person has a list of Address objects. Take the following Function:

 Function<Person, List<Address>> addressFunction = new Function<Person, List<Address>>() {
     public List<Address> valueOf(Person person) {
         return person.getAddresses();
     }
 };
 MutableList<Person> people = ...;
 

Using collect returns a collection of collections of addresses.

 MutableList<List<Address>> addresses = people.collect(addressFunction);
 

Using flatCollect returns a single flattened list of addresses.

 MutableList<Address> addresses = people.flatCollect(addressFunction);
