12. Annotate exceptions

sasmodels.exception

Utility to add annotations to python exceptions.

exception sasmodels.exception.WindowsError

Bases: Exception

Fake WindowsException when not on Windows.

__cause__

__class__

alias of type

__context__

__delattr__(name, /)

Implement delattr(self, name).

__dict__ = mappingproxy({'__module__': 'sasmodels.exception', '__firstlineno__': 10, '__doc__': '\nFake WindowsException when not on Windows.\n', '__static_attributes__': (), '__weakref__': <attribute '__weakref__' of 'WindowsError' objects>, '__annotations_cache__': {}})

__dir__()

Default dir() implementation.

__doc__ = '\nFake WindowsException when not on Windows.\n'

__eq__(value, /)

Return self==value.

__firstlineno__ = 10

__format__(format_spec, /)

Default object formatter.

Return str(self) if format_spec is empty. Raise TypeError otherwise.

__ge__(value, /)

Return self>=value.

__getattribute__(name, /)

Return getattr(self, name).

__getstate__()

Helper for pickle.

__gt__(value, /)

Return self>value.

__hash__()

Return hash(self).

__init__(*args, **kwargs)

classmethod __init_subclass__()

This method is called when a class is subclassed.

The default implementation does nothing. It may be overridden to extend subclasses.

__le__(value, /)

Return self<=value.

__lt__(value, /)

Return self<value.

__module__ = 'sasmodels.exception'

__ne__(value, /)

Return self!=value.

classmethod __new__(*args, **kwargs)

__reduce__()

Helper for pickle.

__reduce_ex__(protocol, /)

Helper for pickle.

__repr__()

Return repr(self).

__setattr__(name, value, /)

Implement setattr(self, name, value).

__setstate__(state, /)

__sizeof__()

Size of object in memory, in bytes.

__static_attributes__ = ()

__str__()

Return str(self).

classmethod __subclasshook__(object, /)

Abstract classes can override this to customize issubclass().

This is invoked early on by abc.ABCMeta.__subclasscheck__(). It should return True, False or NotImplemented. If it returns NotImplemented, the normal algorithm is used. Otherwise, it overrides the normal algorithm (and the outcome is cached).

__suppress_context__

__traceback__

__weakref__

list of weak references to the object

add_note(note, /)

Add a note to the exception

args

with_traceback(tb, /)

Set self.__traceback__ to tb and return self.

sasmodels.exception.annotate_exception(msg, exc=None)

Add an annotation to the current exception, which can then be forwarded to the caller using a bare “raise” statement to raise the annotated exception. If the exception exc is provided, then that exception is the one that is annotated, otherwise sys.exc_info is used.

Example:

>>> D = {}
>>> try:
...    print(D['hello'])
... except:
...    annotate_exception("while accessing 'D'")
...    raise
Traceback (most recent call last):
    ...
KeyError: "hello while accessing 'D'"
