Methods
-
distinct([dynamic keySelector(TValue)?])
→ Iterable<TValue>
-
Returns a subset of this Iterable containing every element whose key is
not equal to the key of any previous element.
-
firstOrNullWhere(bool selector(TValue))
→ TValue?
-
Returns the first element of the iterable which matches the selector,
null if none matches the selector or the iterable is empty.
-
groupBy<TKey>(TKey selector(TValue))
→ Map<TKey, List<TValue>>
-
Groups elements of this
iterable by comparing the selector result.
-
mapIndexed<TResult>(TResult toElement(TValue, int))
→ Iterable<TResult>
-
Returns an Iterable containing the results of all elements processed
by the
toElement function.
-
max([dynamic selector(TValue)?])
→ TValue
-
Finds the element with the largest value selected by the selector function.
-
min([dynamic selector(TValue)?])
→ TValue
-
Finds the element with the smallest value selected by the selector function.
-
sequenceEquals(Iterable<TValue> other)
→ bool
-
Deep equality check.
-
split(bool selector(TValue))
→ Tuple<List<TValue>, List<TValue>>
-
Splits the collection into two subsets.
-
whereIs<TCast>()
→ Iterable<TCast>
-
Returns an Iterable containing all elements that are assignable to
TCast while also casting those elements to that type.
-
zip<TOther>(Iterable<TOther> other)
→ Iterable<Tuple<TValue?, TOther?>>
-
Merges every element of this Iterable with the corresponding element
of
other into a Tuple.
