Parameters:

workflowName - The workflow name

Returns:

the any object with the definition

Throws:

ProcessingException - error reading the definition.

public void synchronizeWorkflowDefinition(java.lang.String workflowName,
                                 boolean isDeleted)
                                   throws ProcessingException

Description copied from interface: WorkflowProcessor

reload the workflow definition from persistence and deploy it, or undeploy it. This can be called to notify the processor that the definition has been changed by someone else, e.g. another cluster node.

Specified by:
