Method Details

publishToStreaming

boolean publishToStreaming()

Checks if streaming is enabled for the current tenant.

Returns:

whether streaming is enabled for the current tenant

distribute

Job distribute(String channelId,
 MediaPackage mediapackage,
 Set<String> elementIds)
        throws DistributionException,
MediaPackageException

Throws:

DistributionException

MediaPackageException

retract

Job retract(String channelId,
 MediaPackage mediaPackage,
 Set<String> elementIds)
     throws DistributionException

Throws:

DistributionException

distributeSync

List<MediaPackageElement> distributeSync(String channelId,
 MediaPackage mediapackage,
 Set<String> elementIds)
                                  throws DistributionException

Distributes the given elements synchronously. This should be used rarely since load balancing will be unavailable. However, since the dispatching logic is bypassed, synchronous execution is much faster. It is useful in interactive scenarios where you synchronously wait for job execution anyway and you don't want to make the user waiting for too long.

Parameters:

channelId - The channel to retract from.

mediapackage - A media package holding the elements to retract.

elementIds - The IDs of the elements to retract.

Returns:

The distributed elements.

Throws:

DistributionException - In case distribution fails.

retractSync

List<MediaPackageElement> retractSync(String channelId,
 MediaPackage mediaPackage,
 Set<String> elementIds)
                               throws DistributionException

Retracts the given elements synchronously. This should be used rarely since load balancing will be unavailable. However, since the dispatching logic is bypassed, synchronous execution is much faster. It is useful in interactive scenarios where you synchronously wait for job execution anyway and you don't want to make the user waiting for too long.

Parameters:

channelId - The channel to retract from.

mediaPackage - A media package holding the elements to retract.

elementIds - The IDs of the elements to retract.

Returns:

The retracted elements.

Throws:

DistributionException - In case retraction fails.
