protected function RouteCompiler::getPathWithoutDefaults

Returns the path of the route, without placeholders with a default value.

When computing the path outline and fit, we want to skip default-value placeholders. If we didn't, the path would never match. Note that this only works for placeholders at the end of the path. Infix placeholders with default values don't make sense anyway, so that should not be a problem.

Parameters

\Symfony\Component\Routing\Route $route: The route to have the placeholders removed from.

Return value

string The path string, stripped of placeholders that have default values.

  // Remove placeholders with default values from the outline, so that they
  // will still match.
