  27. * Autoloader checking if the class is really defined in the file found.
  28. *
  29. * The ClassLoader will wrap all registered autoloaders
  30. * and will throw an exception if a file is found but does
  31. * not declare the class.
  32. *
  33. * It can also patch classes to turn docblocks into actual return types.
  34. * This behavior is controlled by the SYMFONY_PATCH_TYPE_DECLARATIONS env var,
  35. * which is a url-encoded array with the follow parameters:
  36. * - "force": any value enables deprecation notices - can be any of:
  37. * - "phpdoc" to patch only docblock annotations
  38. * - "2" to add all possible return types
  39. * - "1" to add return types but only to tests/final/internal/private methods
  40. * - "php": the target version of PHP - e.g. "7.1" doesn't generate "object" types
  41. * - "deprecations": "1" to trigger a deprecation notice when a child class misses a
  42. * return type while the parent declares an "@return" annotation
  43. *
  44. * Note that patching doesn't care about any coding style so you'd better to run
  45. * php-cs-fixer after, with rules "phpdoc_trim_consecutive_blank_line_separation"
  46. * and "no_superfluous_phpdoc_tags" enabled typically.
