collect

public <V> UnifiedSet<V> collect(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. This method is also commonly called transform or map.

Example using a Java 8 lambda expression:

RichIterable<String> names =
    people.collect(person -> person.getFirstName() + " " + person.getLastName());

Specified by:

flatCollect

public <V> UnifiedSet<V> flatCollect(Function<? super T, ? extends Iterable<V>> function)

Description copied from interface: 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 = Person::getAddresses;
RichIterable<Person> people = ...;

Using collect returns a collection of collections of addresses.

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

Using flatCollect returns a single flattened list of addresses.

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

Specified by:

flatCollect in interface MutableCollection<T>

Specified by:

flatCollect in interface MutableSet<T>

Specified by:

flatCollect in interface RichIterable<T>

Specified by:

collectWith

public <P,A> UnifiedSet<A> collectWith(Function2<? super T, ? super P, ? extends A> function,
 P parameter)

Description copied from interface: RichIterable

Same as RichIterable.collect(Function) with a Function2 and specified parameter which is passed to the block.

Example using a Java 8 lambda expression:

RichIterable<Integer> integers =
    Lists.mutable.with(1, 2, 3).collectWith((each, parameter) -> each + parameter, Integer.valueOf(1));

Specified by:

collectWith in interface MutableCollection<T>

Specified by:

collectWith in interface MutableSet<T>

Specified by:

collectWith in interface RichIterable<T>

Specified by:

parameter - A parameter to pass in for evaluation of the second argument P in function

Returns:

A new RichIterable that contains the transformed elements returned by Function2.value(Object, Object)

See Also:

• RichIterable.collect(Function)

collectIf

public <V> UnifiedSet<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 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());

detect

public T detect(Predicate<? super T> predicate)

Description copied from interface: RichIterable

Returns the first element of the iterable for which the predicate evaluates to true or null in the case where no element returns true. This method is commonly called find.

Person person =
    people.detect(person -> person.getFirstName().equals("John") && person.getLastName().equals("Smith"));

Specified by:

detect in interface RichIterable<T>

Overrides:

detect in class AbstractRichIterable<T>

detectOptional

public Optional<T> detectOptional(Predicate<? super T> predicate)

anySatisfyWith

public <P> boolean anySatisfyWith(Predicate2<? super T, ? super P> predicate,

noneSatisfyWith

public <P> boolean noneSatisfyWith(Predicate2<? super T, ? super P> predicate,

 Function3<? super IV, ? super T, ? super P, ? extends IV> function,
 P parameter)

Description copied from interface: MutableCollection

Returns the final result of evaluating function using each element of the iterable, the previous evaluation result and the parameters.

The parameter value is always used as the third parameter to the function call.

Specified by:

Overrides:

asUnmodifiable

public MutableSet<T> asUnmodifiable()

Description copied from interface: MutableCollection

Returns an unmodifiable view of this collection. This is the equivalent of using Collections.unmodifiableCollection(this) with a return type that supports the full iteration protocols available on MutableCollection. Methods which would mutate the underlying collection will throw UnsupportedOperationExceptions.

Specified by:

asUnmodifiable in interface MutableCollection<T>

Specified by:

asUnmodifiable in interface MutableSet<T>

Returns:

an unmodifiable view of this collection.

See Also:

• Collections.unmodifiableCollection(Collection)

asSynchronized

public MutableSet<T> asSynchronized()

Description copied from interface: MutableCollection

Returns a synchronized wrapper backed by this collection. This is the equivalent of using Collections.synchronizedCollection(this) only with a return type that supports the full iteration protocols available on MutableCollection. 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 in interface MutableCollection<T>

Specified by:

asSynchronized in interface MutableSet<T>

Returns:

a synchronized view of this collection.
