Constructors

EqualitySet(Equality<E> equality)
Creates a set with equality based on equality.
EqualitySet.from(Equality<E> equality, Iterable<E> other)
Creates a set with equality based on equality that contains all elements in other. [...]

Properties

Methods

add(E value) → bool
Adds value to the set. [...]
inherited
addAll(Iterable<E> elements) → void
Adds all elements to this Set. [...]
inherited
any(bool test(E element)) → bool

inherited
cast<T>() → Set<T>
Provides a view of this set as a set of R instances. [...]
inherited
clear() → void
Removes all elements in the set.
inherited
contains(Object element) → bool

inherited
containsAll(Iterable<Object> other) → bool
Returns whether this Set contains all the elements of other.
inherited
difference(Set<Object> other) → Set<E>
Returns a new set with the elements of this that are not in other. [...]
inherited
elementAt(int index) → E
Returns the indexth element. [...]
inherited
every(bool test(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
followedBy(Iterable<E> other) → Iterable<E>
Returns the lazy concatentation of this iterable and other. [...]
inherited
forEach(void f(E element)) → void
Applies the function f to each element of this collection in iteration order.
inherited
intersection(Set<Object> other) → Set<E>
Returns 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(E element), { E orElse() }) → E
Returns the last element that satisfies the given predicate test. [...]
inherited
lookup(Object element) → E
If an object equal to object is in the set, return it. [...]
inherited
map<T>(T f(E element)) → 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
remove(Object value) → bool
Removes value from the set. Returns true if value was in the set. Returns false otherwise. The method has no effect if value value was not in the set.
inherited
removeAll(Iterable<Object> elements) → void

inherited
removeWhere(bool test(E element)) → void

inherited
retype<T>() → Set<T>
inherited
singleWhere(bool test(E element), { E orElse() }) → E
