Base class for implementing Iterable.

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

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.

Properties

E first
read-only, inherited
Returns the first element.
bool isEmpty
read-only, inherited
Returns true if there are no elements in this collection.
bool isNotEmpty
read-only, inherited
Returns true if there is at least one element in this collection.
Iterator<E> iterator
read-only, inherited
Returns a new Iterator that allows iterating the elements of this Iterable.
E last
read-only, inherited
Returns the last element.
int length
read-only, inherited
Returns the number of elements in this.
E single
read-only, inherited
Checks that this iterable has only one element, and returns that element.

Constructors

IterableBase()
const

Methods

any(bool f(E element)) → bool
inherited
Checks whether any element of this iterable satisfies test.
contains(Object element) → bool
inherited
Returns true if the collection contains an element equal to element.
elementAt(int index) → E
inherited
Returns the indexth element.
every(bool f(E element)) → bool
inherited
Checks whether every element of this iterable satisfies test.
expand(Iterable f(E element)) → Iterable
inherited
Expands each element of this Iterableinto zero or more elements.
firstWhere(bool test(E element), {E orElse()}) → E
inherited
Returns the first element that satisfies the given predicate test.
fold(initialValue, dynamic combine(previousValue, E element)) → dynamic
inherited
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
forEach(void f(E element)) → void
inherited
Applies the function f to each element of this collection in iteration order.
join([String separator = ""]) → String
inherited
Converts each element to a String and concatenates the strings.
lastWhere(bool test(E element), {E orElse()}) → E
inherited
Returns the last element that satisfies the given predicate test.
map(dynamic f(E element)) → Iterable
inherited
Returns a new lazy Iterable with elements that are created by calling f on each element of this Iterable in iteration order.
reduce(E combine(E value, E element)) → E
inherited
Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
singleWhere(bool test(E element)) → E
inherited
Returns the single element that satisfies test.
skip(int n) → Iterable<E>
inherited
Returns an Iterable that provides all but the first count elements.
skipWhile(bool test(E value)) → Iterable<E>
inherited
Returns an Iterable that skips leading elements while test is satisfied.
take(int n) → Iterable<E>
inherited
Returns a lazy iterable of the count first elements of this iterable.
takeWhile(bool test(E value)) → Iterable<E>
inherited
Returns a lazy iterable of the leading elements satisfying test.
toList({bool growable: true}) → List<E>
inherited
Creates a List containing the elements of this Iterable.
toSet() → Set<E>
inherited
Creates a Set containing the same elements as this iterable.
toString() → String
inherited
Returns a string representation of (some of) the elements of this.
where(bool f(E element)) → Iterable<E>
inherited
Returns a new lazy Iterable with all elements that satisfy the predicate test.
