Method Details

start

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

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

jobContext - 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.

protected void setCropService(CropService cropService)

Callback for declarative services configuration that will introduce us to the crop service. Implementation assumes that the reference is configured as being static.

Parameters:

Callback for declarative services configuration that will introduce us to the local workspace service. Implementation assumes that the reference is configured as being static.

Parameters:

workspace - an instance of the workspace

setServiceRegistry

public void setServiceRegistry(ServiceRegistry serviceRegistry)

Description copied from class: AbstractWorkflowOperationHandler

Sets the service registry. This method is here as a convenience for developers that need the registry to do job waiting.

Overrides:

Parameters:

serviceRegistry - the service registry
