struct AnyColumnSlice

A type-erased column slice.

Members (16)

get · iOS 15.0+

startIndex

TypeScript

get startIndex(): number

Swift declaration

var startIndex: Int { get }

The index of the initial element in the column slice.

get · iOS 15.0+

description

TypeScript

get description(): string

Swift declaration

var description: String { get }

A text representation of the column slice.

get · iOS 15.0+

customMirror

TypeScript

get customMirror(): SDKHandle

Swift declaration

var customMirror: Mirror { get }

A mirror that reflects the column slice.

get · iOS 15.0+

missingCount

TypeScript

get missingCount(): number

Swift declaration

var missingCount: Int { get }

The number of missing elements in the column slice.

get · iOS 15.0+

debugDescription

TypeScript

get debugDescription(): string

Swift declaration

var debugDescription: String { get }

A text representation of the column slice suitable for debugging.

get · iOS 15.0+

name

TypeScript

get name(): string

Swift declaration

var name: String { get set }

The name of the slice's parent column.

set · iOS 15.0+

name

TypeScript

set name(value: string)

Swift declaration

var name: String { get set }

The name of the slice's parent column.

get · iOS 15.0+

count

TypeScript

get count(): number

Swift declaration

var count: Int { get }

The number of elements in the column slice.

method · iOS 15.0+

index

TypeScript

indexAfter(i: number): number

Swift declaration

func index(after i: Int) -> Int

Returns the index immediately after an element index. - Parameter i: A valid index to an element in the column slice.

method · iOS 15.0+

index

TypeScript

indexBefore(i: number): number

Swift declaration

func index(before i: Int) -> Int

Returns the index immediately before an element index. - Parameter i: A valid index to an element in the column slice.

method · iOS 15.0+

isNil

TypeScript

isNil(index: number): boolean

Swift declaration

func isNil(at index: Int) -> Bool

Returns a Boolean that indicates whether the element at the index is missing. - Parameter index: An index.

method · iOS 15.0+

summary

TypeScript

summary(): AnyCategoricalSummary

Swift declaration

func summary() -> AnyCategoricalSummary

Generates a categorical summary of the column slice's elements. The method tries to cast the the untyped column slice to a typed column slice before summarizing. Generating a summary for a typed column is faster and more efficient than for an untyped column.

method · iOS 15.0+

distinct

TypeScript

distinct(): AnyColumnSlice

Swift declaration

func distinct() -> AnyColumnSlice

Generates a column slice that contains unique elements. The method only adds the first of multiple elements with the same value --- the element with the smallest index --- to the slice. - Returns: A type-erased column slice.

get · iOS 15.0+

endIndex

TypeScript

get endIndex(): number

Swift declaration

var endIndex: Int { get }

The index of the final element in the column slice.

subscript · iOS 15.0+

subscript

TypeScript

subscript(range: SDKHandle): AnyColumnSlice

Swift declaration

subscript(range: Range<Int>) -> AnyColumnSlice { get set }

Accesses a contiguous range of elements. - Parameter range: A range of valid indices in the column slice.

subscript · iOS 15.0+

subscript

TypeScript

subscript88042(position: number): (unknown) | null

Swift declaration

subscript(position: Int) -> Any? { get set }

Accesses an element at an index. - Parameter position: A valid index to an element in the column slice.
