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.
