no setterinherited
Methods
-
add(
V value) → bool -
Adds
value
to the set.inherited -
addAll(
Iterable< V> elements) → void -
Adds all
elements
to this set.inherited -
any(
bool test(V element)) → bool -
Checks whether any element of this iterable satisfies
test
.inherited -
cast<
T> () → Set< T> -
A view of this iterable as an iterable of
R
instances.override -
clear(
) → void -
Removes all elements from the set.
inherited
-
contains(
Object? element) → bool -
Whether the collection contains an element equal to
element
.inherited -
containsAll(
Iterable< Object?> other) → bool -
Whether this set contains all the elements of
other
.inherited -
difference(
Set< Object?> other) → Set<V> -
Creates a new set with the elements of this that are not in
other
.inherited -
elementAt(
int index) → V -
Returns the
index
th element.inherited -
every(
bool test(V element)) → bool -
Checks whether every element of this iterable satisfies
test
.inherited -
expand<
T> (Iterable< T> toElements(V element)) → Iterable<T> -
Expands each element of this Iterable into zero or more elements.
inherited
-
firstWhere(
bool test(V element), {V orElse()?}) → V -
The first element that satisfies the given predicate
test
.inherited -
fold<
T> (T initialValue, T combine(T previousValue, V element)) → T -
Reduces a collection to a single value by iteratively combining each
element of the collection with an existing value
inherited
-
followedBy(
Iterable< V> other) → Iterable<V> -
Creates the lazy concatenation of this iterable and
other
.inherited -
forEach(
void action(V element)) → void -
Invokes
action
on each element of this iterable in iteration order.inherited -
fromIterator(
V anchor, {bool reversed = false, bool inclusive = true}) → TreeIterator< V> -
Returns a TreeIterator that starts at
anchor
. By default, the iterator includes the anchor with the first movement; setinclusive
to false if you want to exclude the anchor. Setreversed
to true to change the direction of of moveNext and movePrevious. -
intersection(
Set< Object?> other) → Set<V> -
Creates a new set which is the intersection between this set and
other
.inherited -
join(
[String separator = ""]) → String -
Converts each element to a String and concatenates the strings.
inherited
-
lastWhere(
bool test(V element), {V orElse()?}) → V -
The last element that satisfies the given predicate
test
.inherited -
lookup(
Object? object) → V? -
If an object equal to
object
is in the set, return it.inherited -
map<
T> (T toElement(V e)) → Iterable< T> -
The current elements of this iterable modified by
toElement
.inherited -
nearest(
V object, {TreeSearch nearestOption = TreeSearch.NEAREST}) → V -
Search the tree for the matching
object
or thenearestOption
if missing. See TreeSearch. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
reduce(
V combine(V value, V element)) → V -
Reduces a collection to a single value by iteratively combining elements
of the collection using the provided function.
inherited
-
remove(
Object? value) → bool -
Removes
value
from the set.inherited -
removeAll(
Iterable< Object?> elements) → void -
Removes each element of
elements
from this set.inherited -
removeWhere(
bool test(V element)) → void -
Removes all elements of this set that satisfy
test
.inherited -
retainAll(
Iterable< Object?> elements) → void -
Removes all elements of this set that are not elements in
elements
.inherited -
retainWhere(
bool test(V element)) → void -
Removes all elements of this set that fail to satisfy
test
.inherited -
singleWhere(
bool test(V element), {V orElse()?}) → V -
The single element that satisfies
test
.inherited -
skip(
int count) → Iterable< V> -
