UnmodifiableListView class

An unmodifiable List view of another List.

The source of the elements may be a List or any Iterable with efficient Iterable.length and Iterable.elementAt.

Inheritance

• Object

inherited

Returns an unmodifiable Map view of this.

clear() → void

inherited

This operation is not supported by an unmodifiable list.

contains(Object element) → bool

inherited

Returns true if the collection contains an element equal to element.

elementAt(int index) → E

inherited

every(bool test(E element)) → bool

inherited

Checks whether every element of this iterable satisfies test.

expand<T>(Iterable<T> f(E element)) → Iterable<T>

firstWhere(bool test(E element), { E orElse() }) → E

inherited

Returns the first element that satisfies the given predicate test.

fold<T>(T initialValue, T combine(T previousValue, E element)) → T

inherited

Reduces a collection to a single value by iteratively combining each element of the collection with an existing value

forEach(void action(E element)) → void

inherited

Applies the function f to each element of this collection in iteration order.

getRange(int start, int end) → Iterable<E>

inherited

lastIndexOf(Object element, [ int startIndex ]) → int

inherited

Returns the last index in the list a of the given element, starting the search at index startIndex to 0. Returns -1 if element is not found.

lastWhere(bool test(E element), { E orElse() }) → E

inherited

Returns the last element that satisfies the given predicate test.

map<T>(T f(E element)) → Iterable<T>

inherited

Returns a new lazy Iterable with elements that are created by calling f on each element of this Iterable in iteration order.

noSuchMethod(Invocation invocation) → dynamic

inherited

Invoked when a non-existent method or property is accessed.

reduce(E combine(E previousValue, E element)) → E

inherited
