Method Details
-
of
This method will take a MutableSortedBag and wrap it directly in a UnmodifiableSortedBag. -
asUnmodifiable
Description copied from interface:MutableCollection
Returns an unmodifiable view of this collection. This is the equivalent of usingCollections.unmodifiableCollection(this)
with a return type that supports the full iteration protocols available onMutableCollection
. Methods which would mutate the underlying collection will throw UnsupportedOperationExceptions.- Specified by:
asUnmodifiable
in interfaceMutableCollection<T>
- Specified by:
asUnmodifiable
in interfaceMutableSortedBag<T>
- Overrides:
asUnmodifiable
in classAbstractUnmodifiableMutableCollection<T>
- Returns:
- an unmodifiable view of this collection.
- 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
in interfaceMutableCollection<T>
- Specified by:

flatCollect
Description copied from interface:MutableCollection
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);
Co-variant example for MutableCollection:Function<Person, List<Address>> addressFunction = Person::getAddresses; MutableCollection<Person> people = ...; MutableCollection<List<Address>> addresses = people.collect(addressFunction); MutableCollection<Address> addresses = people.flatCollect(addressFunction);

with
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 ofFixedSizeCollection
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:

Description copied from interface:MutableCollection

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 ofFixedSizeCollection
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.- Specified by:

withAll
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 ofFixedSizeCollection
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.
