InfiniteIterable<T> class
A base class for Iterable
s of infinite length that throws
UnsupportedError
for methods that would require the Iterable to
terminate.

Methods
-
any(
bool test(T element)) → bool -
Checks whether any element of this iterable satisfies
test
. [...]inherited -
cast<
R> () → Iterable< R> -
Provides a view of this iterable as an iterable of
R
instances. [...]inherited -
contains(

Returns true if the collection contains an element equal to
element
. [...]inherited -
elementAt(
int index) → T -
Returns the
index
th element. [...]inherited -
every(
bool test(T element)) → bool -
Checks whether every element of this iterable satisfies
test
. [...]override -
expand<
T> (Iterable< T> f(T element)) → Iterable<T> -
Expands each element of this
Iterable
into zero or more elements. [...]inherited -
firstWhere(
bool test(T element), {T orElse()}) → T -
Returns the first element that satisfies the given predicate
test
. [...]inherited -
fold<
T1> (T1 initialValue, T1 combine(T1 previousValue, T element)) → T1 -
Reduces a collection to a single value by iteratively combining each
element of the collection with an existing value [...]
override
-
followedBy(
Iterable< T> other) → Iterable<T> -
Returns the lazy concatenation of this iterable and
other
. [...]inherited -
forEach(
void f(T element)) → void -
Applies the function
f
to each element of this collection in iteration order.override -
join(
[String separator = '']) → String -
Converts each element to a
String
and concatenates the strings. [...]override -
lastWhere(
bool test(T value), {T orElse()}) → T -
Returns the last element that satisfies the given predicate
test
. [...]override -
map<
T> (T f(T e)) → Iterable< T> -
Returns a new lazy
Iterable
with elements that are created by callingf
on each element of thisIterable
in iteration order. [...]inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed. [...]
inherited
-
reduce(
T combine(T value, T element)) → T -
Reduces a collection to a single value by iteratively combining elements
of the collection using the provided function. [...]
override
-
singleWhere(
bool test(T value), {T orElse()}) → T -
Returns the single element that satisfies
test
. [...]override -
skip(
int count) → Iterable< T> -
Returns an
Iterable
that provides all but the firstcount
elements. [...]inherited -
skipWhile(
bool test(T value)) → Iterable< T> -
Returns an
Iterable
that skips leading elements whiletest
is satisfied. [...]inherited -
take(
int count) → Iterable< T> -
Returns a lazy iterable of the
count
first elements of this iterable. [...]inherited -

List
containing the elements of thisIterable
. [...]override -
toSet(
) → Set< T> -
Creates a
Set
containing the same elements as this iterable. [...]override -
toString(
) → String -
