Satisfied Interfaces: Category, Cloneable<Clone>, Collection<Element>, Container, ContainerWithFirstElement<Element,Null>, Correspondence<Key,Item>, FixedSized<Element>, Iterable<Element>, List<Element>, None<Element>, Ranged<Index,Span>, Sized

A sequence with no elements. The type of the expression {}.

Attributes
clone	Source Code shared actual Empty clone Returns an `Empty`.
coalesced	Source Code shared actual Empty coalesced The non-null elements of this `Iterable`, in their original order. For null elements of the original `Iterable`, there is no entry in the resulting iterable object.
first	Source Code shared actual Nothing first The first element. Should produce `null` if the container is empty, that is, for any instance for which `empty` evaluates to `true`.
iterator	Source Code shared actual Iterator<Element> iterator Returns an iterator that is already exhausted.
last	Source Code shared actual Nothing last The last element. Should produce `null` if the container is empty, that is, for any instance for which `empty` evaluates to `true`.
lastIndex	Source Code shared actual Nothing lastIndex Returns `null`.
reversed	Source Code shared actual Empty reversed Returns an `Empty`.
sequence	Source Code shared actual Empty sequence Returns an `Empty`.
size	Source Code shared actual Integer size Returns 0.
string	Source Code shared actual String string Returns a string description of the empty List: `{}`.

Methods
any	Source Code shared actual Boolean any(Boolean selecting(Bottom element)) Return `true` if at least one element satisfies the predicate function.
by	Source Code shared actual Empty by(Integer step) Produce an `Iterable` containing every `step`th element of this iterable object. If the step size is `1`, the `Iterable` contains the same elements as this iterable object. The step size must be greater than zero. The expression (0..10).by(3) results in an iterable object with the elements `0`, `3`, `6`, and `9` in that order.
collect	Source Code shared actual Empty collect<Result>(Result collecting(Bottom element)) A sequence containing the results of applying the given mapping to the elements of this container. An eager counterpart to `map()`.
contains	Source Code shared actual Boolean contains(Object element) Returns `false` for any given element.
count	Source Code shared actual Integer count(Boolean selecting(Bottom element)) Returns 0 for any given predicate.
defines	Source Code shared actual Boolean defines(Integer index) Determines if there is a value defined for the given key.
every	Source Code shared actual Boolean every(Boolean selecting(Bottom element)) Return `true` if all elements satisfy the predicate function.
filter	Source Code shared actual Empty filter(Boolean selecting(Bottom element)) An `Iterable` containing the elements of this container that satisfy the given predicate.
find	Source Code shared actual Nothing find(Boolean selecting(Bottom element)) The first element which satisfies the given predicate, if any, or `null` otherwise.
fold	Source Code shared actual Result fold<Result>(Result initial, Result accumulating(Result partial, Bottom element)) The result of applying the accumulating function to each element of this container in turn.
item	Source Code shared actual Nothing item(Integer index) Returns `null` for any given index.
map	Source Code shared actual Empty map<Result>(Result collecting(Bottom element)) An `Iterable` containing the results of applying the given mapping to the elements of to this container.
segment	Source Code shared actual Empty segment(Integer from, Integer length) Returns an `Empty` for any given segment.
select	Source Code shared actual Empty select(Boolean selecting(Bottom element)) A sequence containing the elements of this container that satisfy the given predicate. An eager counterpart to `filter()`.
skipping	Source Code shared actual Empty skipping(Integer skip) Produce an `Iterable` containing the elements of this iterable object, after skipping the first `skip` elements. If this iterable object does not contain more elements than the specified number of elements, the `Iterable` contains no elements.
sort	Source Code shared actual Empty sort(Comparison? comparing(Bottom a, Bottom b)) A sequence containing the elements of this container, sorted according to a function imposing a partial order upon the elements. For convenience, the functions `byIncreasing()` and `byDecreasing()` produce a suitable comparison function: "Hello World!".sort(byIncreasing((Character c) c.lowercased)) This operation is eager by nature.
span	Source Code shared actual Empty span(Integer from, Integer? to) Returns an `Empty` for any given span.
taking	Source Code shared actual Empty taking(Integer take) Produce an `Iterable` containing the first `take` elements of this iterable object. If the specified number of elements is larger than the number of elements of this iterable object, the `Iterable` contains the same elements as this iterable object.
withLeading	Source Code shared actual Sequence<Element> withLeading<Other>(Other other) Returns a new `List` that starts with the specified element, followed by the elements of this `List`.
withTrailing	Source Code shared actual Sequence<Element> withTrailing<Other>(Other other) Returns a new `List` that contains the specified element appended to the end of this `List`s' elements.
