                              throws WorkflowOperationException

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.
