Methods

any(bool test(Identifier element)) → bool
Checks whether any element of this iterable satisfies test.
inherited
cast<R>() → Iterable<R>
A view of this iterable as an iterable of R instances.
inherited
contains(Object? element) → bool
Whether the collection contains an element equal to element.
inherited
elementAt(int index) → Identifier
Returns the indexth element.
inherited
every(bool test(Identifier element)) → bool
Checks whether every element of this iterable satisfies test.
inherited
expand<T>(Iterable<T> toElements(Identifier element)) → Iterable<T>
Expands each element of this Iterable into zero or more elements.
inherited
findIn(ResourceCollection collection) → Resource?
Finds the referenced resource in the collection.
firstWhere(bool test(Identifier element), {Identifier orElse()?}) → Identifier
The first element that satisfies the given predicate test.
inherited
fold<T>(T initialValue, T combine(T previousValue, Identifier element)) → T
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
inherited
followedBy(Iterable<Identifier> other) → Iterable<Identifier>
Creates the lazy concatenation of this iterable and other.
inherited
forEach(void action(Identifier element)) → void
Invokes action on each element of this iterable in iteration order.
inherited
join([String separator = ""]) → String

inherited
lastWhere(bool test(Identifier element), {Identifier orElse()?}) → Identifier
The last element that satisfies the given predicate test.
inherited
map<T>(T toElement(Identifier e)) → Iterable<T>
The current elements of this iterable modified by toElement.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
reduce(Identifier combine(Identifier value, Identifier element)) → Identifier
Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
inherited
singleWhere(bool test(Identifier element), {Identifier orElse()?}) → Identifier
The single element that satisfies test.
inherited
skip(int count) → Iterable<Identifier>
Creates an Iterable that provides all but the first count elements.
inherited
skipWhile(bool test(Identifier value)) → Iterable<Identifier>

inherited
take(int count) → Iterable<Identifier>

inherited
toJson() → Map<String, dynamic>
override
toList({bool growable = true}) → List<Identifier>

inherited
toString() → String
Returns a string representation of (some of) the elements of this.
inherited
where(bool test(Identifier element)) → Iterable<Identifier>
