struct FlattenCollectionIndex<BaseElements : CollectionType where BaseElements.Generator.Element : CollectionType> A position in a FlattenCollection. Inheritance Equatable, ForwardIndexType, _Incrementable View Protocol Hierarchy → Import import Swift Instance Methods func advancedBy(_:) Returns the result of advancing self by n positions. Returns: - If n > 0, the result of applying successor to self n times. - If n < 0, the result of applying predecessor to self -n times. - Otherwise, self. Requires: n >= 0 if only conforming to ForwardIndexType Complexity: - O(1) if conforming to RandomAccessIndexType - O(abs(n)) otherwise Declaration func advancedBy(n: FlattenCollectionIndex<BaseElements>.Distance) -> FlattenCollectionIndex<BaseElements> Declared In ForwardIndexType func advancedBy(_:limit:) Returns the result of advancing self by n positions, or until it equals limit. Returns: - If n > 0, the result of applying successor to self n times but not past limit. - If n < 0, the result of applying predecessor to self -n times but not past limit. - Otherwise, self. Requires: n >= 0 if only conforming to ForwardIndexType. Complexity: - O(1) if conforming to RandomAccessIndexType - O(abs(n)) otherwise Declaration func advancedBy(n: FlattenCollectionIndex<BaseElements>.Distance, limit: FlattenCollectionIndex<BaseElements>) -> FlattenCollectionIndex<BaseElements> Declared In ForwardIndexType func distanceTo(_:) Measure the distance between self and end. Requires: - start and end are part of the same sequence when conforming to RandomAccessSequenceType. - end is reachable from self by incrementation otherwise. Complexity: - O(1) if conforming to RandomAccessIndexType - O(n) otherwise, where n is the function's result. Declaration func distanceTo(end: FlattenCollectionIndex<BaseElements>) -> FlattenCollectionIndex<BaseElements>.Distance Declared In ForwardIndexType func successor() Returns the next consecutive value after self. Requires: The next value is representable. Declaration func successor() -> FlattenCollectionIndex<BaseElements>
