Member predicate Express::RouteHandlerExpr::getAMatchingAncestor

Gets a route handler that precedes this one (not necessarily immediately), may handle same request method, and matches on the same path or a prefix.

If the preceding handler’s path cannot be determined, it is assumed to match.

Note that this predicate is not complete: path globs such as '*' are not currently handled, and relative paths of subrouters are not modelled. In particular, if an outer router installs a route handler r1 on a path that matches the path of a route handler r2 installed on a subrouter, r1 will not be recognized as an ancestor of r2.
