Class: Failure Twisted-0.17.4/twisted/python/failure.py

A basic abstraction for an error that has occurred.

This is necessary because Python's built-in error mechanisms are inconvenient for asynchronous communication.

Methods   
__getstate__
__init__
__repr__
getBriefTraceback
getErrorMessage
printBriefTraceback
printDetailedTraceback
printTraceback
trap
  __getstate__ 
__getstate__ ( self )

Avoid pickling objects in the traceback.

  __init__ 
__init__ (
        self,
        exc_value=None,
        exc_type=None,
        exc_tb=None,
        )

Initialize me with an explanation of the error.

By default, this will use the current exception (sys.exc_info()). However, if you want to specify a particular kind of failure, you can pass an exception as an argument.

  __repr__ 
__repr__ ( self )

  getBriefTraceback 
getBriefTraceback ( self )

  getErrorMessage 
getErrorMessage ( self )

  printBriefTraceback 
printBriefTraceback ( self,  file=None )

Print a traceback as densely as possible.

  printDetailedTraceback 
printDetailedTraceback ( self,  file=None )

Print a traceback with detailed locals and globals information.

  printTraceback 
printTraceback ( self,  file=None )

Emulate Python's standard error reporting mechanism.

  trap 
trap ( self,  *errorTypes )

Trap this failure if its type is in a predetermined list.

This allows you to trap a Failure in an error callback. It will be automatically re-raised if it is not a type that you expect.

Exceptions   
self
