Description copied from interface:SortedBag

asUnmodifiable
Description copied from interface:MutableSortedBag
Returns an unmodifiable view of the set.- Specified by:
asUnmodifiable
in interfaceMutableCollection<T>
- Specified by:
asUnmodifiable
in interfaceMutableSortedBag<T>
- Returns:
- an unmodifiable view of this set
- See Also:
Collections.unmodifiableCollection(Collection)
-
asSynchronized
Description copied from interface:MutableCollection
Returns a synchronized wrapper backed by this collection. This is the equivalent of usingCollections.synchronizedCollection(this)
only with a return type that supports the full iteration protocols available onMutableCollection
. The preferred way of iterating over a synchronized collection is to use the internal iteration methods which are properly synchronized internally.MutableCollection synchedCollection = collection.asSynchronized(); ... synchedCollection.forEach(each -> ... ); synchedCollection.select(each -> ... ); synchedCollection.collect(each -> ... );
If you want to iterate using an imperative style, you must protect external iterators using a synchronized block. This includes explicit iterators as well as JDK 5 style for loops.- Specified by:
asSynchronized

- Specified by:

- Returns:
- a synchronized view of this collection.

collectIf
public <V> MutableList<V> collectIf(Predicate<? super T> predicate, Function<? super T,? extends V> function)Description copied from interface:RichIterable
Returns a new collection with the results of applying the specified function on each element of the source collection, but only for those elements which return true upon evaluation of the predicate. This is the the optimized equivalent of calling iterable.select(predicate).collect(function).Example using a Java 8 lambda and method reference:
RichIterable<String> strings = Lists.mutable.with(1, 2, 3).collectIf(e -> e != null, Object::toString);
Example using Predicates factory:
RichIterable<String> strings = Lists.mutable.with(1, 2, 3).collectIf(Predicates.notNull(), Functions.getToString());

flatCollect
Description copied from interface:RichIterable
flatCollect
is a special case ofRichIterable.collect(Function)
. Withcollect
, when theFunction
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 eachPerson
has a list ofAddress
objects. Take the followingFunction
:Function<Person, List<Address>> addressFunction = Person::getAddresses; RichIterable<Person> people = ...;
Usingcollect
returns a collection of collections of addresses.RichIterable<List<Address>> addresses = people.collect(addressFunction);
UsingflatCollect
returns a single flattened list of addresses.RichIterable<Address> addresses = people.flatCollect(addressFunction);
