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.

    A boolean value indicating whether LPMetadataProvider should download secondary resources specified by the metadata, like the icon, image, or video.

  - 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.

```
    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.

  - timeout
```
public double timeout()
