8. def all(s: Strategy): Strategy

   Traversal to all children.

   Traversal to all children. Construct a strategy that applies s to all term children of the subject term. If s succeeds on all of the children, then succeed, forming a new term from the constructor of the original term and the result of s for each child. If s fails on any child, fail. If there are no children, succeed. If s succeeds on all children producing the same terms (by eq for references and by == for other values), then the overall strategy returns the subject term. This operation works on finite Rewritable, Product, Map and Traversable values, checked for in that order. Children of a Rewritable (resp. Product, collection) value are processed in the order returned by the value's deconstruct (resp. productElement, foreach) method. s is evaluated at most once.

    Traversal to a single child. Construct a strategy that applies s to the ith child of the subject term (counting from one). If s succeeds on the ith child producing t, then succeed, forming a new term that is the same as the original term except that the ith child is now t. If s fails on the ith child or the subject term does not have an ith child, then fail. child(i, s) is equivalent to Stratego's i(s) operator. If s succeeds on the ith child producing the same term (by eq for references and by == for other values), then the overall strategy returns the subject term. This operation works for instances of Product or finite Seq values. s is evaluated at most once.

103. def restorealways(s: Strategy, rest: Strategy): Strategy

     Construct a strategy that applies s, then applies the restoring action rest regardless of the success or failure of s.

     Construct a strategy that applies s, then applies the restoring action rest regardless of the success or failure of s. The whole strategy preserves the success or failure of s. Typically useful if s performs side effects that should be restored always, e.g., when maintaining scope information.

     Define a rewrite rule using a partial function f.

     Define a rewrite rule using a partial function f. If the function is defined at the current term, then the strategy succeeds with the return value of the function applied to the current term. Otherwise the strategy fails.

109. def rulefs(f: ==>[Any, Strategy]): Strategy

     Define a rewrite rule using a function f that returns a strategy.

     Define a rewrite rule using a function f that returns a strategy. The rule applies the function to the subject term to get a strategy which is then applied again to the subject term. In other words, the function is only used for effects such as pattern matching. The whole thing also fails if f is not defined at the term in the first place.

112. def some(s: Strategy): Strategy

     Traversal to as many children as possible, but at least one.

     Traversal to as many children as possible, but at least one. Construct a strategy that applies s to the term children of the subject term. If s succeeds on any of the children, then succeed, forming a new term from the constructor of the original term and the result of s for each succeeding child, with other children unchanged. In the event that the strategy fails on all children, then fail. If there are no children, fail. If s succeeds on children producing the same terms (by eq for references and by == for other values), then the overall strategy returns the subject term. This operation works on instances of finite Rewritable, Product, Map and Traversable values, checked for in that order. Children of a Rewritable (resp. Product, collection) value are processed in the order returned by the value's deconstruct (resp. productElement, foreach) method. s is evaluated at most once.
