        public boolean hasItemConformingToTypeIdentifier​(java.lang.String typeIdentifier)
        Returns YES if the item provider has at least one item that conforms to the supplied type identifier.

      • initWithContentsOfURL

        public NSItemProvider initWithContentsOfURL​(NSURL fileURL)
        Initialize an NSItemProvider with load handlers for the given file URL, and the file content. A type identifier is inferred from the file extension.

      • initWithItemTypeIdentifier

        public NSItemProvider initWithItemTypeIdentifier​(NSSecureCoding item,
                                                 java.lang.String typeIdentifier)
        Initialize an NSItemProvider with an object assigned to a single UTI. `item` is retained.

      • loadItemForTypeIdentifierOptionsCompletionHandler

        public void loadItemForTypeIdentifierOptionsCompletionHandler​(java.lang.String typeIdentifier,
                                                              NSDictionary<?,​?> options,

        Loads the best matching item for a type identifier. The returned object depends on the class specified for the completion handler's `item` parameter. See the table above for coercion rules.

      • loadPreviewImageWithOptionsCompletionHandler

        public void loadPreviewImageWithOptionsCompletionHandler​(NSDictionary<?,​?> options,
                                                         NSItemProvider.Block_loadPreviewImageWithOptionsCompletionHandler completionHandler)
        Loads the preview image for this item by either calling the supplied preview block or falling back to a QuickLook-based handler. This method, like loadItemForTypeIdentifier:options:completionHandler:, supports implicit type coercion for the item parameter of the completion block. Allowed value classes are: NSData, NSURL, UIImage/NSImage.

      • registeredTypeIdentifiers

        public NSArray<java.lang.String> registeredTypeIdentifiers()
        Returns the list of registered type identifiers, in the order they were registered.

      • hasRepresentationConformingToTypeIdentifierFileOptions

        public boolean hasRepresentationConformingToTypeIdentifierFileOptions​(java.lang.String typeIdentifier,
                                                                      long fileOptions)

      • initWithObject

        public NSItemProvider initWithObject​(NSItemProviderWriting object)
        Instantiate an NSItemProvider by querying an object for its eligible type identifiers via the NSItemProviderWriting protocol.

      • loadFileRepresentationForTypeIdentifierCompletionHandler

        public NSProgress loadFileRepresentationForTypeIdentifierCompletionHandler​(java.lang.String typeIdentifier,
                                                                           NSItemProvider.Block_loadFileRepresentationForTypeIdentifierCompletionHandler completionHandler)
        Writes a copy of the data to a temporary file. This file will be deleted when the completion handler returns. Your program should copy or move the file within the completion handler.

      • loadInPlaceFileRepresentationForTypeIdentifierCompletionHandler

        public NSProgress loadInPlaceFileRepresentationForTypeIdentifierCompletionHandler​(java.lang.String typeIdentifier,
                                                                                  NSItemProvider.Block_loadInPlaceFileRepresentationForTypeIdentifierCompletionHandler completionHandler)
        Open the original file in place, if possible. If a file is not available for opening in place, a copy of the file is written to a temporary location, and `isInPlace` is set to NO. Your program may then copy or move the file, or the system will delete this file at some point in the future.

      • preferredPresentationSize

        public CGSize preferredPresentationSize()
        Estimated presentation size, in points. CGSizeZero value indicates this information is not available.

      • previewImageHandler

        public NSItemProvider.Block_previewImageHandler_ret previewImageHandler()
        Sets a custom preview image handler block for this item provider. The returned item should preferably be NSData or a file NSURL.

      • registerFileRepresentationForTypeIdentifierFileOptionsVisibilityLoadHandler

        public void registerFileRepresentationForTypeIdentifierFileOptionsVisibilityLoadHandler​(java.lang.String typeIdentifier,
                                                                                        long fileOptions,
                                                                                        long visibility,

        Registers a file-backed representation. Set `coordinated` to YES if the returned file must be accessed using NSFileCoordinator. If `NSItemProviderFileOptionOpenInPlace` is not provided, the file provided will be copied before the load handler returns.

      • setPreviewImageHandler

        public void setPreviewImageHandler​(NSItemProvider.Block_setPreviewImageHandler value)
        Sets a custom preview image handler block for this item provider. The returned item should preferably be NSData or a file NSURL.
