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
Iterableto a string. -
iterableToShortString(
Iterable iterable, [ String leftDelimiter = '(', String rightDelimiter = ')' ]) → String -
Convert an
Iterableto a string like IterableBase.toString.
Constructors
- IterableBase()
-
const
Properties
- first → E
-
Returns the first element.
read-only, inherited - hashCode → int
-
Get a hash code for this object.
read-only, inherited - isEmpty → bool
-
Returns
trueif 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
Iteratorthat allows iterating the elements of thisIterable.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.

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
fto 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
fon each element of thisIterablein 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
countelements.inherited -
skipWhile(
bool test(E value)) → Iterable<E> -
Returns an
Iterablethat skips leading elements whiletestis satisfied.inherited -
take(
int count) → Iterable<E> -
Returns a lazy iterable of the
countfirst 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.inherited
