  21. * Autoloader checking if the class is really defined in the file found.

  23. * The ClassLoader will wrap all registered autoloaders
  24. * and will throw an exception if a file is found but does
  25. * not declare the class.
  26. *
  27. * It can also patch classes to turn docblocks into actual return types.
  28. * This behavior is controlled by the SYMFONY_PATCH_TYPE_DECLARATIONS env var,
  29. * which is a url-encoded array with the follow parameters:
  30. * - "force": any value enables deprecation notices - can be any of:
  31. * - "docblock" to patch only docblock annotations
  32. * - "object" to turn union types to the "object" type when possible (not recommended)
  33. * - "1" to add all possible return types including magic methods
  34. * - "0" to add possible return types excluding magic methods
  35. * - "php": the target version of PHP - e.g. "7.1" doesn't generate "object" types
  36. * - "deprecations": "1" to trigger a deprecation notice when a child class misses a
  37. * return type while the parent declares an "@return" annotation
  38. *
  39. * Note that patching doesn't care about any coding style so you'd better to run
  40. * php-cs-fixer after, with rules "phpdoc_trim_consecutive_blank_line_separation"
  41. * and "no_superfluous_phpdoc_tags" enabled typically.
