Methods

any(bool test(Path<V, num> 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) → Path<V, num>
Returns the indexth element.
inherited
every(bool test(Path<V, num> element)) → bool
Checks whether every element of this iterable satisfies test.
inherited
expand<T>(Iterable<T> toElements(Path<V, num> element)) → Iterable<T>
Expands each element of this Iterable into zero or more elements.
inherited
firstWhere(bool test(Path<V, num> element), {Path<V, num> orElse()?}) → Path<V, num>
The first element that satisfies the given predicate test.
inherited
fold<T>(T initialValue, T combine(T previousValue, Path<V, num> element)) → T
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
inherited
followedBy(Iterable<Path<V, num>> other) → Iterable<Path<V, num>>
Creates the lazy concatenation of this iterable and other.
inherited
forEach(void action(Path<V, num> element)) → void
Invokes action on each element of this iterable in iteration order.
inherited
join([String separator = ""]) → String
Converts each element to a String and concatenates the strings.
inherited
lastWhere(bool test(Path<V, num> element), {Path<V, num> orElse()?}) → Path<V, num>
The last element that satisfies the given predicate test.
inherited
map<T>(T toElement(Path<V, num> 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(Path<V, num> combine(Path<V, num> value, Path<V, num> element)) → Path<V, num>
Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
inherited
singleWhere(bool test(Path<V, num> element), {Path<V, num> orElse()?}) → Path<V, num>
The single element that satisfies test.
inherited
skip(int count) → Iterable<Path<V, num>>
Creates an Iterable that provides all but the first count elements.
inherited
skipWhile(bool test(Path<V, num> value)) → Iterable<Path<V, num>>
Creates an Iterable that skips leading elements while test is satisfied.
inherited
take(int count) → Iterable<Path<V, num>>
Creates a lazy iterable of the count first elements of this iterable.
inherited
takeWhile(bool test(Path<V, num> value)) → Iterable<Path<V, num>>
Creates a lazy iterable of the leading elements satisfying test.
inherited
toList({bool growable = true}) → List<Path<V, num>>
Creates a List containing the elements of this Iterable.
inherited
toSet() → Set<Path<V, num>>
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(Path<V, num> element)) → Iterable<Path<V, num>>
Creates a new lazy Iterable with all elements that satisfy the predicate test.
inherited
whereType<T>() → Iterable<T>
Creates a new lazy Iterable with all elements that have type T.
