def filter(self, category=Warning, message="", module=None):
            """
            Add a new suppressing filter or apply it if the state is entered.
            Parameters
            ----------
            category : class, optional
                Warning class to filter
            message : string, optional
                Regular expression matching the warning message.
            module : module, optional
                Module to filter for. Note that the module (and its file)
                must match exactly and cannot be a submodule. This may make
                it unreliable for external modules.
            Notes
            -----
            When added within a context, filters are only added inside
            the context and will be forgotten when the context is exited.
