Source Code for Module AccessEngine.AEDevice.AEOutput.AEOutputError

 1  ''' 
 2  Defines a hierarchy of L{AEOutput} exceptions that are raised when some device 
 3  operation fails. A hierarchy of exceptions is used rather than a single  
 4  exception with various error codes to support the catching of a particular  
 5  subtree of the hierarchy, a single kind of exception, or all exceptions.
