The code registry engine.
Drupal maintains an internal registry of all functions or classes in the system, allowing it to lazy-load code files as needed (reducing the amount of code that must be parsed on each request).
|drupal_autoload_class||includes/bootstrap.inc||Confirm that a class is available.|
|drupal_autoload_interface||includes/bootstrap.inc||Confirm that an interface is available.|
|registry_get_parsed_files||includes/registry.inc||Return the list of files in registry_file|
|registry_rebuild||includes/bootstrap.inc||Rescan all enabled modules and rebuild the registry.|
|registry_update||includes/bootstrap.inc||Update the registry based on the latest files listed in the database.|
|_registry_check_code||includes/bootstrap.inc||Helper to check for a resource in the registry.|
|_registry_parse_file||includes/registry.inc||Parse a file and save its function and class listings.|
|_registry_parse_files||includes/registry.inc||Parse all files that have changed since the registry was last built, and save their function and class listings.|
