public static function RouteCompiler::compile

public static RouteCompiler::compile(Route $route)

Compiles the current route instance.

Because so much of the parent class is private, we need to call the parent class's compile() method and then dissect its return value to build our new compiled object. If upstream gets refactored so we can subclass more easily then this may not be necessary.

Parameters

\Symfony\Component\Routing\Route $route: A Route instance.

Return value

\Drupal\Core\Routing\CompiledRoute A CompiledRoute instance.

Overrides RouteCompiler::compile

File

core/lib/Drupal/Core/Routing/RouteCompiler.php, line 33

Class

RouteCompiler

Compiler to generate derived information from a Route necessary for matching.

Namespace

Drupal\Core\Routing

Code

public static function compile(Route $route) {

  $symfony_compiled = parent::compile($route);

  // The Drupal-specific compiled information.
  $stripped_path = static::getPathWithoutDefaults($route);
  $fit = static::getFit($stripped_path);
  $pattern_outline = static::getPatternOutline($stripped_path);
  // We count the number of parts including any optional trailing parts. This
  // allows the RouteProvider to filter candidate routes more efficiently.
  $num_parts = count(explode('/', trim($route->getPath(), '/')));

  return new CompiledRoute(
  $fit, 
  $pattern_outline, 
  $num_parts, 
  // These are the Symfony compiled parts.
