Iterables<E> extension

Provides functions for transforming Iterables to other collections.

Functions that rely on the ordering of elements are non-deterministic if an iterable is unordered, i.e. HashSet.

Properties

indexed → Iterable<(int, E)>: Available on Iterable<E>, provided by the Iterables extension
Returns a lazy iterable with records that contain an iteration index and element.
no setter

associate<R>({required Select<E, R> by}) → Map<R, E>: Available on Iterable<E>, provided by the Iterables extension
Returns a map that associates values returned by by with elements in this iterable.
distinct({required Select<E, Object?> by}) → Iterable<E>: Available on Iterable<E>, provided by the Iterables extension
Returns a lazy iterable with only distinct elements.
toMap<K, V>((K, V) create(E element)) → Map<K, V>: Available on Iterable<E>, provided by the Iterables extension
Returns a modifiable map using create to produce entries from elements in this iterable.
toUnmodifiableList() → List<E>: Available on Iterable<E>, provided by the Iterables extension
Transforms this iterable into an unmodifiable List.
toUnmodifiableMap<K, V>((K, V) create(E element)) → Map<K, V>: Available on Iterable<E>, provided by the Iterables extension
Returns an unmodifiable map using create to produce entries from elements in this iterable.
toUnmodifiableSet() → Set<E>: Available on Iterable<E>, provided by the Iterables extension
Transforms this iterable into an unmodifiable Set.
