class twisted.internet.defer.FirstError(Exception): (source)

First error to occur in a DeferredList if fireOnOneErrback is set.

Instance Variable	subFailure	The `Failure` that occurred.
Instance Variable	index	The index of the `Deferred` in the `DeferredList` where it happened.
Method	__init__	Undocumented
Method	__repr__	The repr of `FirstError` instances includes the repr of the wrapped failure's exception and the index of the `FirstError`.
Method	__str__	The str of `FirstError` instances includes the str of the entire wrapped failure (including its traceback and exception) and the index of the `FirstError`.
Method	__cmp__	No summary

subFailure = (source)

The Failure that occurred.

(type: Failure)

index = (source)

The index of the Deferred in the DeferredList where it happened.

(type: int)

def __init__(self, failure, index): (source)

def __repr__(self): (source)

The repr of FirstError instances includes the repr of the wrapped failure's exception and the index of the FirstError.

Returns Undocumented (type: str)

def __str__(self): (source)

The str of FirstError instances includes the str of the entire wrapped failure (including its traceback and exception) and the index of the FirstError.

Returns Undocumented (type: str)

def __cmp__(self, other): (source)

Comparison between FirstError and other FirstError instances is defined as the comparison of the index and sub-failure of each instance. FirstError instances don't compare equal to anything that isn't a FirstError instance.
