[Kotlin] Collection hierachy

read-only interface (Mutable이 붙지 않은 것들)- element의 값을 변경 불가

mutable interface (Mutable이 붙은 것들)- element의 값을 변경 가능( 삭제,변경,추가)

 

interface Iterable<out T>

Classes that inherit from this interface can be represented as a sequence of elements that can be iterated over.

https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-iterable/

 

interface Collection<out E> : Iterable<E>

A generic collection of elements. Methods in this interface support only read-only access to the collection;

read/write access is supported through the MutableCollection interface.

https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-collection/

 

interface MutableIterable<out T> : Iterable<T>

Classes that inherit from this interface can be represented as a sequence of elements that can be iterated over and that supports removing elements during iteration.

https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-mutable-iterable/

 

interface MutableCollection<E> : Collection<E>, MutableIterable<E>

A generic collection of elements that supports adding and removing elements.

https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-mutable-collection/#kotlin.collections.MutableCollection

 

interface List<out E> : Collection<E>

A generic ordered collection of elements. Methods in this interface support only read-only access to the list; read/write access is supported through the MutableList interface.

https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-list/#kotlin.collections.List

 

interface Set<out E> : Collection<E>

A generic unordered collection of elements that does not support duplicate elements. Methods in this interface support only read-only access to the set; read/write access is supported through the MutableSet interface.

https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-set/#kotlin.collections.Set

 

interface MutableList<E> : List<E>, MutableCollection<E>

A generic ordered collection of elements that supports adding and removing elements.

https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-mutable-list/#kotlin.collections.MutableList

 

interface MutableSet<E> : Set<E>, MutableCollection<E>

A generic unordered collection of elements that does not support duplicate elements, and supports adding and removing elements.

https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-mutable-set/#kotlin.collections.MutableSet

 

interface Map<K, out V>

A collection that holds pairs of objects (keys and values) and supports efficiently retrieving the value corresponding to each key. Map keys are unique; the map holds only one value for each key. Methods in this interface support only read-only access to the map; read-write access is supported through the MutableMap interface.

https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-map/#kotlin.collections.Map

 

interface MutableMap<K, V> : Map<K, V>

A modifiable collection that holds pairs of objects (keys and values) and supports efficiently retrieving the value corresponding to each key. Map keys are unique; the map holds only one value for each key.

https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-mutable-map/#kotlin.collections.MutableMap
