IndexingGenerator

struct IndexingGenerator<C : _CollectionType>

A generator for an arbitrary collection. Provided C conforms to the other requirements of CollectionType, IndexingGenerator<C> can be used as the result of C's generate() method. For example:

struct MyCollection : CollectionType {
  struct Index : ForwardIndexType { *implementation hidden* }
  subscript(i: Index) -> MyElement { *implementation hidden* }
  func generate() -> **IndexingGenerator<MyCollection>** {
    return IndexingGenerator(self)
  }
}

Initializers

init(_:)

Create a generator over the given collection

Declaration

init(_ seq: C)

Instance Methods

func generate()

Return a generator over the elements of this sequence.

Complexity: O(1)

Declaration

func generate() -> IndexingGenerator<C>

mutating func next()

Advance to the next element and return it, or nil if no next element exists.

Requires: no preceding call to self.next() has returned nil.

Declaration

mutating func next() -> C._Element?
