   *   An associative array of parameters to replace in the route path,

   *   values.

   *   Example:
   *   [
   *     'parameter1' => 'value1',

   *   @endcode
   *   This will transform a route path such as
   *   '/route/path/{parameter1}{parameter2}' into '/route/path/value1'.

   * @return string
   *   The generated path with all placeholders either replaced by their
   *   corresponding values or removed if no matching parameter exists.
