Abstract Value Members

  1. abstract def apply(check: CheckingCallback)(tm1: Term, tm2: Term, tp: Option[Term])(implicit stack: Stack, history: History): Option[Continue[Boolean]]

    check

    provides callbacks to the currently solved system of judgments

    tm1

    the first term

    tm2

    the second term

    tp

    their type if known

    stack

    their context

    history

    the history so far

    returns

    Some(cont) continuation function to apply the rule None if this rule is not applicable

  5. def applicable(tm1: Term, tm2: Term): Boolean

    returns

    true if the rule is applicable to tm1 == tm2 This method should fail quickly if possible; the apply method may still fail even it this returned true.
