static initContentTypeExportingImporting(contentType: _UniformTypeIdentifiers_UTType, exporting: ((arg0: string) => Promise<ArrayBuffer>), importing: ((arg0: ArrayBuffer) => Promise<string>)): DataRepresentation<string>

Swift declaration

init(contentType: UTType, exporting: @escaping @Sendable (Item) async throws -> Data, importing: @escaping @Sendable (Data) async throws -> Item)

Creates a representation that allows transporting an item as binary data. - Parameters: - contentType: A uniform type identifier that best describes the item. - exporting: A closure that provides a data representation of the given item. - importing: A closure that instantiates the item with given binary data.

static initExportedContentTypeExporting(exportedContentType: _UniformTypeIdentifiers_UTType, exporting: ((arg0: string) => Promise<ArrayBuffer>)): DataRepresentation<string>

Swift declaration

init(exportedContentType: UTType, exporting: @escaping @Sendable (Item) async throws -> Data)

Creates a representation that allows exporting an item as binary data. - Parameters: - exportedContentType: A uniform type identifier that best describes the item. - exporting: A closure that provides a data representation of the given item.

Swift declaration

init(importedContentType: UTType, importing: @escaping @Sendable (Data) async throws -> Item)

Creates a representation that allows importing an item as binary data. - Parameters: - importedContentType: A uniform type identifier that best describes the item. - importing: A closure that instantiates the item with given binary data

Swift declaration

init(contentType: UTType, shouldAttemptToOpenInPlace: Bool = false, exporting: @escaping @Sendable (Item) async throws -> SentTransferredFile, importing: @escaping @Sendable (ReceivedTransferredFile) async throws -> Item)

Creates a transfer representation for importing and exporting transferable items as files. - Parameters: - contentType: A uniform type identifier that best describes the item. - shouldAttemptToOpenInPlace: A Boolean value that indicates whether the receiver gains access to the original item on disk and can edit it, or to a copy made by the system. - exporting: A closure that provides a file representation of the given item. - importing: A closure that instantiates the item with given file promise. The file referred to by the ``ReceivedTransferredFile/file`` property of the ``ReceivedTransferredFile`` instance is only guaranteed to exist within the `importing` closure. If you need the file to be around for a longer period, make a copy in the `importing` closure.

static initExportedContentTypeShouldAllowToOpenInPlaceExporting(exportedContentType: _UniformTypeIdentifiers_UTType, shouldAllowToOpenInPlace: boolean, exporting: ((arg0: string) => Promise<SentTransferredFile>)): FileRepresentation<string>

Swift declaration

init(exportedContentType: UTType, shouldAllowToOpenInPlace: Bool = false, exporting: @escaping @Sendable (Item) async throws -> SentTransferredFile)

Creates a transfer representation for exporting transferable items as files. - Parameters: - exportedContentType: A uniform type identifier for the file `URL`, returned by the `exporting` closure. - shouldAllowToOpenInPlace: A Boolean value that indicates whether the receiver can try to gain access to the original item on disk and can edit it. If `false`, the receiver only has access to a copy of the file made by the system. - exporting: A closure that provides a file representation of the given item.

static initImportedContentTypeShouldAttemptToOpenInPlaceImporting(importedContentType: _UniformTypeIdentifiers_UTType, shouldAttemptToOpenInPlace: boolean, importing: ((arg0: ReceivedTransferredFile) => Promise<string>)): FileRepresentation<string>

Swift declaration

init(importedContentType: UTType, shouldAttemptToOpenInPlace: Bool = false, importing: @escaping @Sendable (ReceivedTransferredFile) async throws -> Item)

Creates a transfer representation for importing transferable items as files. - Parameters: - importedContentType: A uniform type identifier for the file promise, returned by the `exporting` closure. - shouldAttemptToOpenInPlace: A Boolean value that indicates whether the receiver wants to gain access to the original item on disk and can edit it. If `false`, the receiver only has access to a copy of the file made by the system. - importing: A closure that creates the item with given file promise. The file referred to by the `file` property of the `ReceivedTransferredFile` is only guaranteed to exist within the `importing` closure. If you need the file to be around for a longer period, make a copy in the `importing` closure.
