org.opencastproject.workflow.api.AbstractWorkflowOperationHandler

org.opencastproject.workflow.handler.assetmanager.SelectVersionWorkflowOperationHandler

All Implemented Interfaces:

WorkflowOperationHandler

public class SelectVersionWorkflowOperationHandler
extends AbstractWorkflowOperationHandler

Replaces the media package in the current workflow with a previous version from the asset manager. There are two ways to choose the version: by version number or a combination of source-flavors and no-tags (choose the latest version where elements with source-flavor do not have the tags specified in no-tags. This operation should be the first one in a workflow executed from the archive because it REPLACES the media package used by the current workflow.

Method Details

start

public WorkflowOperationResult start(WorkflowInstance workflowInstance,
 JobContext context)
                              throws WorkflowOperationException

Description copied from class: AbstractWorkflowOperationHandler

Runs the workflow operation on this WorkflowInstance. If the execution fails for some reason, this must throw a WorkflowOperationException in order to handle the problem gracefully. Runtime exceptions will cause the entire workflow instance to fail.

Specified by:

start in interface WorkflowOperationHandler

Specified by:

start in class AbstractWorkflowOperationHandler

Parameters:

workflowInstance - the workflow instance

context - the job context

Returns:

the WorkflowOperationResult containing a potentially modified MediaPackage and whether to put the workflow instance into a wait state.

Throws:

WorkflowOperationException - If the workflow operation fails to execute properly, and the default error handling should be invoked.
