with

default MutableSortedBag<T> with(T element)

Description copied from interface: MutableCollection

This method allows mutable and fixed size collections the ability to add elements to their existing elements. In order to support fixed size a new instance of a collection would have to be returned taking the elements of the original collection and appending the new element to form the new collection. In the case of mutable collections, the original collection is modified, and is returned. In order to use this method properly with mutable and fixed size collections the following approach must be taken:

 MutableCollection<String> list = list.with("1");
 list = list.with("2");
 return list;
 

In the case of FixedSizeCollection a new instance of MutableCollection will be returned by with, and any variables that previously referenced the original collection will need to be redirected to reference the new instance. For other MutableCollection types you will replace the reference to collection with the same collection, since the instance will return "this" after calling add on itself.

Specified by:

with in interface MutableBagIterable<T>

Specified by:

with in interface MutableCollection<T>

• Collection.add(Object)

without

default MutableSortedBag<T> without(T element)

Description copied from interface: MutableCollection

This method allows mutable and fixed size collections the ability to remove elements from their existing elements. In order to support fixed size a new instance of a collection would have to be returned containing the elements that would be left from the original collection after calling remove. In the case of mutable collections, the original collection is modified, and is returned. In order to use this method properly with mutable and fixed size collections the following approach must be taken:

 MutableCollection<String> list = list.without("1");
 list = list.without("2");
 return list;
 

In the case of FixedSizeCollection a new instance of MutableCollection will be returned by without, and any variables that previously referenced the original collection will need to be redirected to reference the new instance. For other MutableCollection types you will replace the reference to collection with the same collection, since the instance will return "this" after calling remove on itself.

• Collection.remove(Object)

withAll

default MutableSortedBag<T> withAll(Iterable<? extends T> elements)

Description copied from interface: MutableCollection

This method allows mutable and fixed size collections the ability to add multiple elements to their existing elements. In order to support fixed size a new instance of a collection would have to be returned taking the elements of the original collection and appending the new elements to form the new collection. In the case of mutable collections, the original collection is modified, and is returned. In order to use this method properly with mutable and fixed size collections the following approach must be taken:

 MutableCollection<String> list = list.withAll(FastList.newListWith("1", "2"));
 

In the case of FixedSizeCollection a new instance of MutableCollection will be returned by withAll, and any variables that previously referenced the original collection will need to be redirected to reference the new instance. For other MutableCollection types you will replace the reference to collection with the same collection, since the instance will return "this" after calling addAll on itself.

Specified by:

withAll in interface MutableBagIterable<T>

Specified by:

withAll in interface MutableCollection<T>

See Also:

• Collection.addAll(Collection)

withoutAll

default MutableSortedBag<T> withoutAll(Iterable<? extends T> elements)

Description copied from interface: MutableCollection

This method allows mutable and fixed size collections the ability to remove multiple elements from their existing elements. In order to support fixed size a new instance of a collection would have to be returned containing the elements that would be left from the original collection after calling removeAll. In the case of mutable collections, the original collection is modified, and is returned. In order to use this method properly with mutable and fixed size collections the following approach must be taken:

 MutableCollection<String> list = list.withoutAll(FastList.newListWith("1", "2"));
 

In the case of FixedSizeCollection a new instance of MutableCollection will be returned by withoutAll, and any variables that previously referenced the original collection will need to be redirected to reference the new instance. For other MutableCollection types you will replace the reference to collection with the same collection, since the instance will return "this" after calling removeAll on itself.

withoutAll in interface MutableCollection<T>

• Collection.removeAll(Collection)

newEmpty

MutableSortedBag<T> newEmpty()

Description copied from interface: MutableCollection

Creates a new empty mutable version of the same collection type. For example, if this instance is a FastList, this method will return a new empty FastList. If the class of this instance is immutable or fixed size (i.e. SingletonList) then a mutable alternative to the class will be provided.

Specified by:

newEmpty in interface MutableCollection<T>

clone

MutableSortedBag<T> clone()

asUnmodifiable

MutableSortedBag<T> asUnmodifiable()

Returns an unmodifiable view of the set.

Specified by:

asUnmodifiable in interface MutableCollection<T>

Returns:

an unmodifiable view of this set

See Also:

• Collections.unmodifiableCollection(Collection)

asSynchronized

MutableSortedBag<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>

Returns:

a synchronized view of this collection.

See Also:

• Collections.synchronizedCollection(Collection)

tap

MutableSortedBag<T> tap(Procedure<? super T> procedure)

Description copied from interface: RichIterable

Executes the Procedure for each element in the iterable and returns this.

Example using a Java 8 lambda expression:

 RichIterable<Person> tapped =
     people.tap(person -> LOGGER.info(person.getName()));
 

Example using an anonymous inner class:

 RichIterable<Person> tapped =
     people.tap(new Procedure<Person>()
     {
         public void value(Person person)
         {
             LOGGER.info(person.getName());

     people.select(person -> person.getAddress().getCity().equals("London"));

flatCollect

<V> MutableList<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);

 Multimap<String, Person> peopleByLastName =
