This enum contains the possible error levels that can be passed to the pdg.WorkItem.addAttrib API function.
Errors are converted to Python exceptions. This is the default behavior.
No exceptions or warnings are reported. A value of
None is returned when a failure occurs.
Errors are displayed as warnings on the node that owns the work item, but will not cause an exception in Python code. A value of
None is also returned when a failure occurs.
