Base class for implementing Iterable.

This class implements all methods of Iterable except Iterable.iterator in terms of iterator.

Inheritance

Static Methods

iterableToFullString(Iterable iterable, [ String leftDelimiter = '(', String rightDelimiter = ')' ]) String

Converts an Iterable to a string.

iterableToShortString(Iterable iterable, [ String leftDelimiter = '(', String rightDelimiter = ')' ]) String

Convert an Iterable to a string like IterableBase.toString.

Constructors

Properties

first → E

Returns the first element.

read-only, inherited
hashCode int

The hash code for this object.

read-only, inherited
isEmpty bool

Returns true if there are no elements in this collection.

read-only, inherited
isNotEmpty bool

Returns true if there is at least one element in this collection.

read-only, inherited
iterator Iterator<E>

Returns a new Iterator that allows iterating the elements of this Iterable.

read-only, inherited
last → E

Returns the last element.

read-only, inherited
length int

Returns the number of elements in this.

read-only, inherited
runtimeType Type

A representation of the runtime type of the object.

read-only, inherited
single → E

Checks that this iterable has only one element, and returns that element.

read-only, inherited

Operators

operator ==(other) bool

The equality operator.

inherited

Methods

any(bool f(E element)) bool

Checks whether any element of this iterable satisfies test.

inherited
contains(Object element) bool

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

inherited
elementAt(int index) → E

Returns the indexth element.

inherited
every(bool f(E element)) bool

Checks whether every element of this iterable satisfies test.

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

Expands each element of this Iterable into zero or more elements.

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

Returns the first element that satisfies the given predicate test.

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

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

inherited
forEach(void f(E element)) → void

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

inherited
join([String separator = "" ]) String

Converts each element to a String and concatenates the strings.

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

Returns the last element that satisfies the given predicate test.

inherited
map<T>(T f(E e)) Iterable<T>

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

inherited
noSuchMethod(Invocation invocation) → dynamic

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

inherited
reduce(E combine(E value, E element)) → E

Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.

inherited
singleWhere(bool test(E element)) → E

Returns the single element that satisfies test.

inherited
skip(int count) Iterable<E>

Returns an Iterable that provides all but the first count elements.

inherited
skipWhile(bool test(E value)) Iterable<E>

Returns an Iterable that skips leading elements while test is satisfied.

inherited
take(int count) Iterable<E>

Returns a lazy iterable of the count first elements of this iterable.

inherited
takeWhile(bool test(E value)) Iterable<E>

Returns a lazy iterable of the leading elements satisfying test.

inherited
toList({bool growable: true }) List<E>

Creates a List containing the elements of this Iterable.

inherited
toSet() Set<E>

Creates a Set containing the same elements as this iterable.

inherited
toString() String

Returns a string representation of (some of) the elements of this.

inherited
where(bool test(E element)) Iterable<E>

Returns a new lazy Iterable with all elements that satisfy the predicate test.
