class heat.engine.clients.client_plugin.ExceptionFilter(should_ignore_ex)

Bases: object

A context manager that prevents some exceptions from being raised.

For backwards compatibility, these objects can also be called with the exception value as an argument - any non-matching exception will be re-raised from this call. We attempt but cannot guarantee to keep the same traceback; the context manager method is preferred for this reason except in cases where the ignored exception affects control flow.

Use this class as a decorator for a function that returns whether a given exception should be ignored. e.g.

>>> @ExceptionFilter
>>> def ignore_assertions(ex):
...     return isinstance(ex, AssertionError)

and then use it as a context manager:

>>> with ignore_assertions:
...     assert False

or call it:

>>> try:
...     assert False
... except Exception as ex:
...     ignore_assertions(ex)
