A Dereference actor that always fails. This can be used as a fallback actor in the Dereference bus. Concretely, it accepts any action in its test phase, but rejects all actions in its run phase. If lenient mode is enabled, the rejection will be silenced.

This module is part of the Comunica framework, and should only be used by developers that want to build their own query engine.
