apple.linkpresentation.LPMetadataProvider

All Implemented Interfaces:

NSObject

public class LPMetadataProvider
extends NSObject

An LPMetadataProvider object retrieves metadata for a given URL.

An instance of LPMetadataProvider can only be asked to retrieve metadata once; a new instance should be created for each request.

A client must have the com.apple.security.network.client entitlement in order to be able to use LPMetadataProvider for remote URLs.

automaticallyNotifiesObserversForKey

public static boolean automaticallyNotifiesObserversForKey(java.lang.String key)

cancel

public void cancel()

Cancel a metadata request.

If the request had not already completed, the completion handler will be invoked with the error code `LPErrorMetadataFetchCancelled`.

cancelPreviousPerformRequestsWithTarget

public static void cancelPreviousPerformRequestsWithTarget(java.lang.Object aTarget)

cancelPreviousPerformRequestsWithTargetSelectorObject

public static void cancelPreviousPerformRequestsWithTargetSelectorObject(java.lang.Object aTarget,
                                                                         org.moe.natj.objc.SEL aSelector,

resolveInstanceMethod

public static boolean resolveInstanceMethod(org.moe.natj.objc.SEL sel)

setShouldFetchSubresources

public void setShouldFetchSubresources(boolean value)

A boolean value indicating whether LPMetadataProvider should download secondary resources specified by the metadata, like the icon, image, or video. If shouldFetchSubresources is set to `NO`, the returned LPLinkMetadata object will consist only of metadata retrieved from the main resource.

The default value is `YES`.

setTimeout

public void setTimeout(double value)

The time interval after which the request will automatically fail if it has not already completed.

If the timeout is reached, no metadata is returned; the completion handler will be invoked with the error code `LPErrorMetadataFetchTimedOut`.

The default timeout is 30 seconds.

setVersion_static

public static void setVersion_static(long aVersion)

shouldFetchSubresources

public boolean shouldFetchSubresources()

A boolean value indicating whether LPMetadataProvider should download secondary resources specified by the metadata, like the icon, image, or video. If shouldFetchSubresources is set to `NO`, the returned LPLinkMetadata object will consist only of metadata retrieved from the main resource.

The default value is `YES`.

startFetchingMetadataForURLCompletionHandler

public void startFetchingMetadataForURLCompletionHandler(NSURL URL,
                                                         LPMetadataProvider.Block_startFetchingMetadataForURLCompletionHandler completionHandler)

Fetch metadata for the given URL.

The completion handler will be called on a non-main queue.

File URLs returned in the resultant LPLinkMetadata will be deleted when the completion handler returns.

An exception will be thrown if this is called more than once on a particular LPMetadataProvider instance.

superclass_static

public static org.moe.natj.objc.Class superclass_static()

timeout

public double timeout()

The time interval after which the request will automatically fail if it has not already completed.

If the timeout is reached, no metadata is returned; the completion handler will be invoked with the error code `LPErrorMetadataFetchTimedOut`.

The default timeout is 30 seconds.

version_static

public static long version_static()

startFetchingMetadataForRequestCompletionHandler

public void startFetchingMetadataForRequestCompletionHandler(NSURLRequest request,
                                                             LPMetadataProvider.Block_startFetchingMetadataForRequestCompletionHandler completionHandler)

Fetch metadata for the given NSURLRequest.

The completion handler will be called on a non-main queue.

File URLs returned in the resultant LPLinkMetadata will be deleted when the completion handler returns.

An exception will be thrown if this is called more than once on a particular LPMetadataProvider instance.
