Method Detail

apply

Proof.State[] apply(Proof.State current,
                    Proof.State head)
             throws wybs.lang.NameResolver.ResolutionError

Apply a given rule to a given state, producing one (or more) potentially updated states. If the rule does not apply or produces no additional information, then the original state is returned untouched.

Parameters:

current - The current state of truth. That is, everything which is known to be true at this point.

head - The current tip of the proof branch. This maybe some distance in the future from the current state, and identifies truths which have yet to be processed.

Returns:

One or more states representing the remaining states to be discharged

Throws:

wybs.lang.NameResolver.ResolutionError
