protocol Sliceable A collection from which a sub-range of elements (a "slice") can be efficiently extracted. Inheritance CollectionType, SequenceType, _CollectionType, _SequenceType, _Sequence_Type, _Sliceable View Protocol Hierarchy → Associated Types SubSlice : _Sliceable The collection type that represents a sub-range of elements. Though it can't currently be enforced by the type system, the SubSlice type in a concrete implementation of Sliceable should also be Sliceable. Generator : GeneratorType A type that provides the sequence's iteration interface and encapsulates its iteration state. Index : ForwardIndexType A type that represents a valid position in the collection. Valid indices consist of the position of every element and a "past the end" position that's not valid for use as a subscript. _Element A type that represents a valid position in the collection. Valid indices consist of the position of every element and a "past the end" position that's not valid for use as a subscript. Import import Swift Instance Variables var endIndex: Index Required The collection's "past the end" position. endIndex is not a valid argument to subscript, and is always reachable from startIndex by zero or more applications of successor(). Declaration var endIndex: Index { get } Declared In _CollectionType var startIndex: Index Required The position of the first element in a non-empty collection. Identical to endIndex in an empty collection. Declaration var startIndex: Index { get } Declared In _CollectionType Subscripts subscript(_: Range<Self.Index>) Required Declaration subscript(bounds: Range<Self.Index>) -> SubSlice { get } subscript(_: Self.Index) Required Declaration subscript(position: Self.Index) -> Self.Generator.Element { get } Declared In CollectionType subscript(_: Index) Required Declaration subscript(_i: Index) -> _Element { get } Declared In _CollectionType Instance Methods func generate() Required Return a generator over the elements of this sequence. Complexity: O(1) Declaration func generate() -> Generator Declared In SequenceType, _Sequence_Type
