CMBlockBuffer.Flags

struct · iOS 13.0+ · SDK 27.1

struct Flags

Flags controlling behaviors and features of `CMBlockBuffer` APIs.

Members (6)

get · iOS 13.0+

alwaysCopyData

TypeScript
get alwaysCopyData(): CMBlockBuffer_Flags
Swift declaration
static let alwaysCopyData: CMBlockBuffer.Flags

Used with `makeContiguous()` to cause it to always produce an allocated copy of the desired data.

get · iOS 13.0+

assureMemoryNow

TypeScript
get assureMemoryNow(): CMBlockBuffer_Flags
Swift declaration
static let assureMemoryNow: CMBlockBuffer.Flags

When passed to routines that accept block allocators, causes the memory block to be allocated immediately.

get · iOS 13.0+

dontOptimizeDepth

TypeScript
get dontOptimizeDepth(): CMBlockBuffer_Flags
Swift declaration
static let dontOptimizeDepth: CMBlockBuffer.Flags

Passed to `append(bufferReference:flags:)` and `init(bufferReference:flags:)` to suppress reference depth optimization.

get · iOS 13.0+

permitEmptyReference

TypeScript
get permitEmptyReference(): CMBlockBuffer_Flags
Swift declaration
static let permitEmptyReference: CMBlockBuffer.Flags

Passed to `append(bufferReference:flags:)` and `init(bufferReference:flags:)` to allow references into a `CMBlockBuffer` that may not yet be populated.

init · iOS 13.0+

init

TypeScript
init(rawValue: number): CMBlockBuffer_Flags
Swift declaration
init(rawValue: UInt32)

Creates a new option set from the given raw value. This initializer always succeeds, even if the value passed as `rawValue` exceeds the static properties declared as part of the option set. This example creates an instance of `ShippingOptions` with a raw value beyond the highest element, with a bit mask that effectively contains all the declared static members. let extraOptions = ShippingOptions(rawValue: 255) print(extraOptions.isStrictSuperset(of: .all)) // Prints "true" - Parameter rawValue: The raw value of the option set to create. Each bit of `rawValue` potentially represents an element of the option set, though raw values may include bits that are not defined as distinct values of the `OptionSet` type.

rawValue

TypeScript
getRawValue($self: CMBlockBuffer_Flags): number
Swift declaration
let rawValue: UInt32

The corresponding value of the raw type. A new instance initialized with `rawValue` will be equivalent to this instance. For example: enum PaperSize: String { case A4, A5, Letter, Legal } let selectedSize = PaperSize.Letter print(selectedSize.rawValue) // Prints "Letter" print(selectedSize == PaperSize(rawValue: selectedSize.rawValue)!) // Prints "true"
